U need to check the following
1) fuel pump relay (check it if it's broken)
2) fuel pump (check it if it works - u must hear a click sound)
3) Coils (check its resistance using ohmmeter)
4) sparkplug wires (check it from corrosion)
good luck

Check for spark, you can get a tester at any parts store, the problem may be crank sensor. also check for fuel, there should be a small scrader valve located on the fuelrail that if you remaove the plastic cap and push will squirt fuel (USE RAG and WEAR SAFTEY GLASSES) Fuel is flamable after all.

My 2002 pt cruiser will not start. Seems to fire but won't start. Found some wires not attached to anything. Is there a kill switch somewhere.


What do you mean by seams to fire but won't Start ? When you turn the key to start what happens ? Does the starter spin the engine ? If so this would be a engine cranks , now if it does spin the engine an the engine doesn't start an run this is call an cranks no start condition .Now on the other hand if the starter doesn't spin the engine when you turn the key to start ,then this is referred to as a no crank - no start . There are very different diagnostic steps for each of these conditions . Your best bet is to have your vehicle diagnosed by a qualified technician .

I have a new battery but the car will still not fire.


Fire ? explain ! When you turn the key to the start position does the engine (starter ) do anything ,spin the engine ? If not ,that is what is referred to as a no crank - no start condition , now if the engine cranks over (spins ) but doesn't start , this is a cranks no start condition . Now which is yours doing or not doing ?

If the neutral saftey switch is bad or anything related, would it cause the car not get any fire


Explain fire ? Ignition spark , engine turning over when key is moved to the start position . It depends on the make vehicle . Back in the old days voltage from the ignition switch when placed in the start position would go through the park neutral switch to the S terminal on the starter solenoid . Causing the starter to spin the engine over . Then the ignition system would have the job of firing the spark plugs causing the air fuel mixture to ignite causing the engine to start an run . Do you have a no- crank no start condition . Sometimes I don't know what you rookies mean , I have been fixing vehicles for over thirty years an you rookies don't talk the same automotive language automotive Technicians talk.

My car cranks but does not start. Is this a starter problem? Is there any way I can check to see if it is the starter that is bad?


If the engine turns over (spins) when you turn the key , your starter is working, if the car doesn't start (run) you will need to check for spark and fuel pressure.

My 1985 720 pickup with a z24 engine will seldom start when it is warm with the ignition switch. It will spin over very well but will not start. I can push it and it starts immediately. It seems as if...


When your engine is CRANKED the voltage/curent feed to the starter is very high that the IGNITION SYSTEM DOES NOT GET THE REQUIRED VOLTAGE.
When the car is pushed it will start immediately as the full voltage is applied on the coil for a good spark.
So you must check the battery, the battery terminals, the ground connections and the starter motor.
If the starter motor has worn out bushes/brushes/pinion then it will drain more current as the starter is turned.
Since there is no firing it is only evident that there will be flooding. So remove plugs and flush out before the engine is cranked.

I have a 1998 Nissan Frontier. It will not start. I have check fuses and starter and battery. Have power but won't start. Cannot locate the Starter Relay Switch. Where exactly is it located?


Does the starter crank the engine over? Saying your truck won't start could mean that the starter spins be the engine won't fire. If the starter is not spinning is it at least clicking?

Vehicle Won't Start


The solution to this problem was simple, embarrasing and frustrating. The dome light was left on, and discharged the battery....enough to prevent the ignition from firing apparently. I did not suspect this, because the starter would turn the engine over very well, for a long time, and would do this repeatedly. In all my experience, I have never seen an engine spin that well and not start. According to the dealer, the voltage was too low for the ignition to work. While I do not know the exact threshhold where the voltage is too low to crank, I could have detected the condition by checking the voltage at the battery while cranking. It should have been significantly below 12 volts, indicating a low battery. The tow truck driver who picked it up simply used a portable battery to jump it off and cranked it with no problem. The symptom of the starter continuing to run after releasing the key is new technology with computerized controls, and is normal nowdays. You don't really notice this because the engine usually fires so quickly that it is undetectable.
