Why Won't My Car Start?
When your engine cranks only won't start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most mutual causes are issues in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter). However, the source may besides exist a mechanical fault (for example, a leaking valve), or faulty components in other systems.
What "crank-no-get-go" doesn't generally mean is a trouble with the starter. If the engine cranks normally, you don't take a starting problem.
Your machine engine needs fuel, pinch, and a spark to start.

If it isn't cranking correct (the engine rotates slowly or doesn't rotate, or yous hear weird noises or goose egg when y'all try to beginning the engine), cheque this other practical guide to troubleshooting the starting arrangement.
Any you do, avoid cranking the engine repeatedly with the hope that the engine will fire upward. You may drain your battery of power and damage the starter motor in the procedure. Instead, endeavor to use the charge left in your battery to locate the fault. In this article, I offer the post-obit:
- Quick Diagnostic Tests
- Exercise You Have Spark?
- Is Fuel Reaching the Cylinders?
- Do You Have Proper Compression?
- Other Possible Components That May Cause a No-Start Condition
This guide volition showtime requite you vi quick things you can check, and so three systems to troubleshoot—the spark, the fuel, the compression—using some simple and quick diagnostics. So, for more assist, you'll run into a listing of components in related systems that can be associated with a no-start condition.
Scanning your machine calculator memory should exist one of your first diagnostic procedures.

1. 6 Quick Checks (Check These Commencement)
When trying to notice out why your car doesn't want to commencement, keep in mind these possibilities.
Fuel
For example, make certain at that place'southward actually fuel in the tank.
Browse the Computer Retentiveness
The computer in modernistic vehicles monitors and controls a adept number of sensors and actuators. Browse your estimator retentivity for trouble codes before you lot do anything else. Fifty-fifty if the cheque engine calorie-free hasn't come on, you may find a awaiting code that can guide you lot in your diagnosis. False input or lack of input from sensors similar the crankshaft position sensor (CKP) or camshaft position sensor (CPS) tin prevent the engine from starting. Besides, a bad throttle position sensor (TPS) may cut off the spark to the cylinders.
Battery
If the engine cranks slowly, yous may be dealing with a discharged battery, loose or corroded bombardment terminals, or starting system wires
Starting Organisation
Bug with the starter motor or circuit can foreclose the engine from starting. You may want to check the circuit voltage driblet or accept the starter motor checked. Pay special attention to unusual racket when cranking.
Security Organisation
Many modern vehicles come equipped with an engine immobilizer as an anti-theft security system. The car's security system may have made an fault that disabled the fuel or ignition organisation or the fleck in the primal may have failed. To troubleshoot a built-in security organization, consult your car possessor's transmission or consult with the shop that installed your alert system.

2. Do You lot Accept Spark?
Outset, you want to cheque that a good spark is reaching the cylinders. You can exercise this test without a spark tester, but it's better to utilize one because a weak spark as well every bit a missing spark can prevent your engine from starting. If possible, apply an adjustable tester so that y'all tin can test for 40KV, 30KV, and 10KV spark.
- Select an easy-to-achieve spark plug and unplug the spark plug wire, or coil wire, or coil on plug (COP).
- Gear up the spark tester to 40KV, and plug information technology in at the cease of the spark plug wire or gyre wire. Hook the spark tester to engine ground. To basis the tester, use an unpainted bracket or bolt on the engine. Notation: If yous are not using a spark tester, grab the wire with a pair of insulated pliers and place the tip of the wire nearly half an inch from the footing (engine cake, bracket, cylinder caput). Y'all still need a helper to crank the engine for you. The rest of the test is the aforementioned. You'll be able to test for the presence of spark but not its force.
- While watching the spark tester, take an assistant creepo the engine.
- You should encounter a bright spark jumping the gap in the spark tester.
If you don't see a spark, repeat the exam. This time, adapt the spark tester to 30KV. If you even so don't see a spark, repeat the test and set the tester to 10KV. If this fourth dimension you see a spark or no spark, you accept a trouble with the ignition system. Consult your vehicle repair manual for your particular model for further diagnosis. Depending on your particular model, you lot may have a problem with an ignition coil, benefactor, ignition module, igniter, or some other related component.
Other Spark Checks You Should Do
- On systems with a distributor: Bank check that the benefactor cap isn't loose; audit the distributor cap for moisture, cracks, carbon traces, or some other damage; there could be faulty distributor components.
- If you oasis't replaced the spark plug wires in more than than three years, your wires may be worn.
- Also, check your auto possessor'southward transmission or vehicle repair manual for the interval schedule for the spark plugs. You lot may need to service (gap cheque and adjustment) or supersede the plugs.
- If you installed new spark plugs and your car refused to outset right after, double-check that you installed the right plugs for your vehicle model, and the plugs have the correct gap. Use a wire feeler gauge to check and adjust the gap.
Fuel injectors may clog and prevent your engine from starting.

3. Is Fuel Reaching the Cylinders?
After checking for spark, you lot need to cheque that the engine is getting fuel.
How to Check a Carburetor or Throttle Torso Injection (TBI) System
- Take the lid off the air filter box and open the throttle plate (carburetor). On TBI systems, watch the fuel injector.
- Ask an banana to creepo the engine and see if fuel is being fed into the unit.
- If you don't see fuel existence injected, your problem is in the fuel organisation. Brand sure of the following:
- yous have enough fuel in the tank,
- the fuel pump is working,
- the fuel filter is not chock-full (consult your automobile owner's transmission or repair transmission for the service schedule),
- the fuel pressure level regulator is working properly
- the fuel injectors are non chock-full.
How to Check a Multiport Fuel Injection System
- First, make sure the fuel pump is working. Momentarily remove the fuel filler cap.
- Inquire an assistant to plough the ignition primal to the On position, simply don't start the engine.
- Every bit your assistant turns the key, listen closely through the filler neck of the fuel tank. You lot should hear the whirring sound of the fuel pump motor being energized for two or three seconds. If you hear the audio, at least you know the pump is getting power; continue with the side by side pace. Otherwise, yous may be dealing with a faulty fuel pump or relay, a blown fuse, an electrical open up or another problem in the fuel pump circuit.
- Detach the air cleaner assembly from the throttle body.
- Open up the throttle plate and spray some starting fluid into the throttle body.
- Creepo the engine.
- If the engine still doesn't seem like it wants to start, probably fuel is getting into the cylinders and your problems prevarication somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Bank check for a chock-full fuel filter, or a bad fuel pressure regulator. Consult your vehicle repair manual, if necessary.
- If the incoming fuel line that goes to the fuel injectors has a test port (Schrader valve—a valve similar to the ane on your tires), utilize a pocket-size screwdriver to printing on the valve. Be ready with a shop rag to catch the fuel.
- Turn the ignition key to the On position for two or three seconds then turn it off. Repeat the step 2 more times to prime the line with fuel.
- And so, press the valve with the screwdriver while catching the fuel with the shop rag. Fuel should squirt out through the valve. Instead, if a dribble of fuel comes out or no fuel, then check for a clogged fuel filter, a bad fuel pump, or a leaking fuel pressure regulator.
- If fuel squirts through the valve, plug a fuel pressure gauge to the exam fitting valve and turn the ignition central to the On position and read the gauge. And so have an assistant crank the engine and read the gauge.
- Compare your gauge readings to the pressure level specification listed in your vehicle repair transmission.
- If the pressure is lower than specification, your problem lies in the fuel system, mayhap a faulty fuel pump, clogging fuel filter, or bad fuel pressure regulator. Detach the vacuum hose from the top of the fuel pressure level regulator. If the line is moisture and smells similar fuel, replace the fuel pressure regulator.
- If the pressure is inside specifications, you tin unplug a fuel injector electrical connector and plug in a nod light to the harness connector (yous may loan a set up of nod lights from your local auto parts store).
- Enquire your banana to crank the engine, while you lookout man the nod low-cal.
- If the nod light flashes while the engine is being cranked, you can at least assume that the injectors are receiving the pulse signal from the computer. If not, you need to check for a blown fuse or bad relay in the fuel injection organisation, a trouble with the figurer control, or problems with input sensors (for example the crankshaft or camshaft position sensors). Scan your figurer for trouble codes. Refer to the list of related components below.
Some Cars Automatically Shut off the Fuel Pump After a Crash
Some models, like many Ford vehicles, take a fuel pump switch (inertia switch), that automatically cuts power to the fuel pump when involved in an accident. If your engine refused to offset subsequently an accident or after a vehicle struck yours in a parking lot, bank check for an inertia switch. The switch helps forbid your car from catching on fire if an accident occurs. Check your machine owner's manual or vehicle repair transmission to locate the switch. Yous can pop the button dorsum in manually.

4. Practice You lot Have Proper Compression?
Compression in the cylinder heats up the air-fuel mixture and helps the spark ignite the mixture and so the combustion takes place. During the combustion process, though, there should be no air leaks. Otherwise, the cylinder will have poor combustion, or it will not happen.
The most common source of air (combustion) leak is a jumped timing belt or chain that allows air to escape through a valve; information technology tin can besides happen considering of a burned valve, worn-out compression rings, or a blown caput gasket.
A timing chugalug or chain synchronizes the camshaft to crankshaft rotation. Afterwards miles of service, it wears downward, becomes damaged, or breaks. And so machine manufacturers suggest replacing a timing belt every 5 years. A timing chain may have a wider service schedule interval. Replacing the belt or chain at the suggested interval can prevent serious engine mechanical issues. Consult your vehicle repair manual.
On some vehicle models, it is like shooting fish in a barrel to remove the timing cover to check if the belt or chain is notwithstanding in identify. If information technology is, you may exist able to visually inspect the belt or chain condition, and then cheque that it hasn't jumped. Follow the instructions in your vehicle repair transmission.
Likewise, you tin can bank check compression pressure using a compression guess. If you have a gasoline engine, you screw the gauge into a spark plug hole; on diesel engines, spiral the guess in place of a glow plug or injector nozzle. Follow the instructions in your vehicle repair manual.
Gasoline engine pinch ranges from 130 to 180 pounds per square inch (psi); diesel engine pinch may range from 250 to 400 psi.
A failed EGR valve can prevent your engine from starting.

5. Other Components That May Crusade a No-Kickoff Condition
Faults in other systems, not simply ignition, fuel, or pinch problems, can forestall your engine from starting. A system component itself may be faulty, or there may be a trouble with its wire connector or harness. Y'all may need to expand your diagnostic process to the components below.
Computers in mod vehicles monitor many of these components (commonly in emission-related systems) and can set trouble codes when problems ascend. And then don't forget to browse your reckoner.
1. EGR
The exhaust gas recirculation (EGR) valve introduces a measured corporeality of exhaust gases into the intake manifold to get re-burned. This helps lower engine temperature and harmful emissions. Just the valve can fail and stick either open up or airtight. When the valve sticks open up it may prevent your engine from starting. Other symptoms of a stuck-open EGR valve include rough idle and stalling.
2. Cold Injector
Some vehicle models employ a cold-start injector. Information technology operates every bit a regular injector, merely simply works when the engine is common cold. The injector may have its own thermo switch or may be commanded by the system control module. If either the switch or the computer circuit fails, yous may accept a difficult time starting the engine during cold months. Consult your vehicle repair manual, if necessary.
3. MAP
The manifold accented pressure level (MAP) sensor compares the barometric (atmospheric) pressure to the intake manifold vacuum. When the sensor fails, it tin can preclude your engine from starting. Not all vehicles utilize this sensor. Consult your vehicle repair manual.
4. MAF
The mass airflow (MAF) sensor tells the computer the amount (the density) of the air inbound the engine. A mutual MAF problem is a dirt or foreign affair blocking the sensing element, preventing the sensor from working. Or the sensor itself may fail after miles of service. You can clean and test the sensor at home.
5. ECT
The computer uses the engine coolant temperature (ECT) sensor to know how much fuel the engine needs and when to enter closed loop operation (that is, when the engine has reached operating temperature). Depending on your particular model, a bad ECT sensor can upset ignition timing or the operation of the transmission or cooling fan. Consult your vehicle repair manual, if necessary.
6. Canister Vent Valve
The canister vent valve is part of the evaporative emissions control (EVAP) system. The EVAP system temporarily stores harmful fuel vapors into a canister to forestall their release into the temper. When atmospheric condition are appropriate, the computer routes the fuel vapors out of the canister through a canister vent valve and into the intake manifold for burning. A faulty valve, though, can forestall the engine from starting. Consult your vehicle repair transmission for the procedure to test the valve.
seven. TPS
The throttle position sensor (TPS) monitors the position of the throttle valve. Information technology sends a voltage signal to the computer. The reckoner uses this information to regulate the air-fuel mixture according to engine needs. On some vehicle models, a worn-out, declining or bad TPS volition preclude your engine from starting at all.
8. Vacuum Leaks
Vacuum leaks are non uncommon, and they are the source of many engine functioning problems, including failure to offset. Depending on where the fault is located, vacuum leaks can be hard to notice. But major vacuum leaks that tin make the engine hard to start may happen in the power booster vacuum hose, EGR valve, another chief vacuum hose, or a diddled head or intake manifold gasket.
nine. Carburetor
If you have an one-time vehicle model with a carburetor, double-check that the fuel level is properly adjusted. If the carburetor is flooded, y'all'll probably perceive a strong fuel scent under the hood. A petty pull a fast one on y'all can utilize is to fully depress the accelerator and try to beginning the engine. If the engine doesn't start, wait for a few minutes and effort once again.
When your engine cranks only fails to start, it can be difficult to fix if yous don't know where to brainstorm troubleshooting. This guide not just tells you where to start only helps yous build your diagnostic strategy. And reminds you lot of some elementary but piece of cake to forget places to look into. So well-nigh of the time, using just this guide you'll exist able to zero in on the problem.

I've noticed that the fuel and oil estimate doesn't motion and the air conditioning doesn't come on when the key is turned to start information technology. But the other gauges work and the radio works. Do yous take any clue what this could be?
Answer: Make sure you're getting spark and fuel. Cheque to see if there are whatsoever trouble codes you can download from the computer. As well, check for fuel pressure and compression.
Question: 1995 Dodge Dakota V6 two cycle drive, cranks only won't offset. No power to pump or ignition. What could be wrong?
Answer: Check the ignition relay. If this fails, it can impact ability to the ignition coil and fuel pump.
Question: My 2000 Chevy suburban 1500 was working fine today, but subsequently in the day I tried turning on the motorcar and information technology just cranked without starting. The lights, radio, wipers etc. work fine just the car won't get-go. I've even tried jumping the battery motorcar but yet won't kickoff, merely crank. Any communication on that?
Answer: The nearly mutual on a crank-nostart status are the ignition and fuel systems. Make sure you got skilful spark and cheque for fuel pressure. Yous may endeavor spraying starting fluid in the throttle while cranking. If information technology sounds like the engine wants to take hold of, probably the fuel system is at mistake.
Question: My 2002 Honda Accord cranks but won't start, and I've already replaced the fuel pump, spark plugs and wires, distributor cap and rotor. And the starter has also been replaced. Any ideas?
Answer: Brand sure you are getting a adept spark. Effort spraying a bit of starting fluid through the throttle plate and crank the engine. If it seems like the engine wants to catch, the problem is in the fuel system. Supercede the fuel filter, if necessary. Check for fuel pressure. The problem could be the fuel pressure regulator or a worn pump.
Question: I'm using a Toyota Brevis 1JZ engine. It's been diagnosed several times, and information technology was reporting throttle motor malfunction. I changed the throttle trunk. Information technology starts one fourth dimension so fails and then it keeps on cranking. Y'all change the throttle body, it repeats the aforementioned process. The spark and pinch is at that place. What could be the problem?
Answer: Check the electric connectors for the throttle control system. Some other possibility is a trouble with the throttle control system actuator, or the harness (open or short).
Question: Why does my Chevy Utility Bakkie backlash when trying to start?
Answer: Check the ignition system and ignition timing.
Question: I have a 2000 Honda Civic that cranks merely sometimes doesn't start. It starts after 30 minutes or won't start later on several hours. It also shut-off while I was driving, I changed the spark plugs and the battery is not dead. Also checked and there is fuel going into the cylinders and didn't seem to observe and whatsoever diddled fuses. Any thoughts?
Answer: The problem could be in the fuel system simply information technology can be hard to diagnose if it is intermittent. You lot may have a leaking fuel injector.
Also, in that location could exist a bad ground or loose wire that is causing too much resistance in the circuit, preventing the engine to showtime until it cools. These other posts may assistance.

Question: I take a 1998 Chevy 1998 K2500 4x4 truck. I've replaced plugs, plug wires, benefactor and new bombardment, fuel filters, fresh fuel. Fuel force per unit area checks out. Engine cranks merely won't start until the whine of fuel pump slightly changes tone. Then it volition start on next attempt. Exercise you think its the fuel pump, even though pressure checks out OK?
Answer: Spray some starting fluid in the throttle body and endeavour starting the engine. If information technology catches for a second or two, then there could be a problem with the fuel pump.
Question: My 2006 Honda Accord has a hard time starting. I have to really press on the gas hard to go it to beginning. What could be the problem?
Answer: In that location could be a problem in the fuel system; check for fuel pressure when trying to starting time. You may have good spark if you lot're able to run the car once information technology starts, but the pump may be weak or worn as well.
Question: I have a 1995 BMW 740 that wont start. If I put starting fluid in the intake, it tries to get-go. If I bypass fuel relay, information technology comes on, merely not with key. Information technology cranks just will not start. What could be the problem?
Answer: Make sure yous don't have a chock-full fuel filter first. This will preclude fuel from reaching the injectors. And so, bank check if the fuel pump kicks in when yous plough the key On. Remove the key completely and then insert the key and turn it On. You lot should here the pump coming 'alive'. If not, try using another relay, or remove the relay and exam information technology. If the pump isn't working, check if yous take whatsoever fuel pressure. There could be a leaking fuel pressure level regulator or a worn, weak pump. You can check fuel pressure through the test (Schrader) valve. These other posts may help:

Question: I have a 98 Chevy Blazer. I have a new bombardment, new plugs, new wires, new fuel filter and information technology still won't commencement when information technology's cold. Once information technology runs, then information technology's practiced. But after virtually viii hours, it is really difficult to offset once more. Why would my Chevy Blazer have trouble starting?
Answer: You lot may want to bank check the starter circuit voltage drop. Too, the starter may already have some wear, making it harder to crank the engine. This postal service might help yous:

As well, continue in mind that when cold, the fuel doesn't evaporate as hands, and the oil tends to be thicker. This makes it harder to kickoff the engine. And, an quondam engine won't have as proficient compression as a newer model, which compounds the problem.
Question: I have a 1999 Nissan Primera model. I went and washed the automobile and it could not start. A mechanic checked and realized that water had entered the ECU. I bought a new one, programmed it, and had it installed. The automobile could still non start. They removed the spark plugs and the cylinders were flooded with petrol. What could be the possible cause of this?
Answer: Make sure the ignition system is producing a good spark; otherwise the computer is injecting fuel that is not getting burned. Too, there could exist a problem with the injection system. If you didn't experience this problem prior to replacing the computer, check these two systems showtime.
Question: I have a 2003 Chrysler Town and Land that will creepo merely it won't turn over. I have already changed out the battery and fuel pump. How can I diagnose the problem with my Chrysler?
Respond: Brand certain you accept good spark and practiced fuel pressure level when cranking. If both check out OK, test the compression.
Question: My 1995 GMC Yukon won't start after I rebuilt the TBI. Could information technology exist flooded?
Answer: Cheque the fuel injectors are working. Double check that the TBI was properly torqued when installed and a new gasket, if necessary. This could exist a faulty fuel system or a vacuum leak. Other possibilities are problems with the throttle position sensor (TPS) and IAC (idle air controller.). Y'all can test the TPS using a digital multimeter:

Examination the IAC using direct bombardment voltage, and have a look at the ports for buildup.
Question: I have a 1992 Subaru Legacy wagon, and my vehicle cranks over but won't commencement. I've replaced the temp sensor, crank sensor, fuel pump and strainer, ringlet, spark plugs, and battery. Nevertheless, it won't start. I've checked compression and fuel. Everything checks out. What could it be?
Answer: Make sure to bank check for problem codes using a code reader. If engine compression and fuel pressure and volume check out, test the spark using an adjustable spark plug tester. Minimum, you should become around 30K V. Check the specs for your model in the vehicle repair manual.
Question: I have a 2014 Ford F150. The auto cranks but won't get-go. I tin disconnect the battery cable and reconnect and it will start, but might not adjacent time. Any ideas what the problem might exist?
Answer: At that place could be a trouble with the engine or starting organization grounds. Possibly these other posts volition help:

Question: I have a 2004 Ford Ranger Border that cranks fine every morning, only after I drive information technology to piece of work and it sits for a few hours, I take to crank it at to the lowest degree twice before it will start up. What could be the problem?
Answer: The engine coolant temperature sensor may be failing, not sending the correct signal when the engine is warmer. But, this can also be a trouble with fuel pressure or a leaking injector. Pace on the gas when cranking the engine. if it starts you may have a leaking injector or pressure level regulator. Otherwise, try some starting fluid. If it helps, the problem could be with the force per unit area regulator.
Question: Have a 350 Chevy, all ready to start, just gas isn't getting to the plugs. What can be the problem?
Answer: Check for fuel pressure. A bad regulator or some other fault in the organisation can preclude fuel from reaching the engine.
Question: I have a 1991 Nissan 300zx. Information technology shut off while I was driving, and it won't kickoff. It was leaking water beforehand. I made frequent stops to refill it, but it cut off and now that it's back it will not turn over. It doesn't leak anything until I crank it, and it's the fuel I believe, only it'southward blackness in color. I have no idea what it could be. What should I practice?
Answer: From your description, there might be an oil leak. Check the oil level. You need to locate the source of the leak. Have a look under the machine and come across if you can see traces of the leak around the oil pan or engine.
Question: My Toyota 1KD engine cranks simply information technology can't offset. What could be the trouble?
Respond: Follow the steps in the beginning department in the postal service to get an idea what system is causing the problem first (ignition, fuel, compression). Then have information technology from there.
