No Spark During Hot Restart

[karl95gt]

I'm a newbie to this forum but I've read pretty extensively through it. Here is my issue:


I've been having an issue with my car for hot re-starts. Last night, I drove the car pretty hard, and I went to go move it to a different spot in the driveway, and it wouldn't start. I got my tester out of the toolbox and found I had to spark at the plugs. This only happens during a hot restart....and is becoming extremely frustrating.

Here is what has been replaced:
Coil
Cap, Rotor, Wires and plugs
Ignition Module (the one on the fenderwell)
PIP Module (early last year sometime -- I forget when)

I've heard it could be the dizzy, but I thought the only electronic gizmo in it was the PIP module....is this true???? Would it be worth to get an aftermarket distributor (MSD, ACCEL, Crane???)

Any help would be appreciated.

If you have spark, the PIP is fine.

When it's hot, if you floor the gas pedal (while AND ONLY WHILE) cranking, does it start?

I'd check for fuel pressure when it's hot and wont start. Also check a plug and see if it's wet.

Good luck.

I think he had a typo because the title says no spark during restart. I was going to say the module but you already replaced it. Did you replace it because of this problem and it still does it? When were all those parts replaced because you may have gotten a bad part from the store. Also, check for current from each of those components when you are having the problem. If your getting power to the distributor then your module is fine. Are you getting power to the coil? If not, then the coil is fine. If it stops at the coil then its bad. It should be fairly easy to track the flow of power and see where it stops.

Thanks Smock (is it Scot?) - I think you're right. I had trouble makin sense of the post in the first place (I had just awoken).

Go through the steps and line of thinking that Smock prescribes and you will find the issue.

The PIP is very likely, as are TFI's. I dont trust parts store parts for poop, so those having been replaced means almost nill.

The quick test: if you have no spark and no injector pulsing, look at the PIP.

If you have no spark but DO have injector pulsing, the PIP should be fine.

Then look at the negative input at the ignition coil. As Smock said, if it's there, the TFI is doing what it should be. If that's ok but the coil doesnt have output, look at the coil.

If this is confusing, we can write out a step by step list that goes in order (we shotgunned it a little bit here).

Good luck.
