Have you tested each wire with a spark tester (available at a parts store for around $10) to verify a lack of spark? there are resistance reading for the primary and secondary circuits in the coils that are pretty accurate testing. but that info may only be available from a repair manual. however, you could remove the coils and test all in comparison to each other. no spark from ALL wires would suggest a possible bad crank or cam sensor, or even a bad ignition module

Ignition trouble shoot


Hey Ron,
AN internal combustion engine requires three (3) things to run...assuming the internals are good.
1. Adequate compression >120PSI
2. A properly timed spark
3. A proper fuel/air ratio

Start with one, and eliminate one at a time(make sure it works) - ..(this is the way a professional would trouble shoot an engine).

Pontiac g6 starting problems


Let's get this straight , in mechanic terms that we can under stand . The engine turns over when you turn the key to the start position ,but will not start an run ! Is this correct ? More then likely fuel or spark but could be a clogged air filter if you never replaced it before ! Pull a plug wire or coil if your vehicle has coil on plug ignition system , use a spark tester an crank the engine . Is there spark ? Spray carburetor cleaner into the throttle plate an crank the engine , does it try to start ? if not fuel pump problem or electrical .

Your best bet would be to take your vehicle to a qualified repair shop ! Wouldn't want you to get hurt or cause any damage to your vehicle from not knowing how to trouble shoot a no start problem . Your vehicle is very complex , computers an electrical circuits for various sensors .

Sometimes car shuts off while driving and then comes back on the next day


You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, fuel pump, or a list of other things.

I recently installed a new ignition coil to my 1996 dodge neon .. I was having issues starting the vehicle. Once it was started, it ran beautifully. But it seems when the car sits idle and not running for...


Seems like a resistor or wire leading to the ignition coil may be at fault.

There's a primary and secondary coil in an ignition coil. And, if the coil isn't getting power, then there's no way for the secondary coil to deliver the spark to the spark plugs.

You may want to take it to an auto electric shop if you have trouble tracing why the wire doesn't have power at the primary coils of the ignition coil.
