Thread: No spark

Fellas I have a 04 GTP Comp G. Only mod is a ZZP PCM.

One day wife driving to work and the car dies. It would not re-start (would crank/no spark). After sitting a bit it would fire right back up. It will drive approx. 15 minutes and dies again.

I've replaced the crank sensor, coils, ignition control module, etc.. It had an aftermarket alarm, it has been totally removed. What else can I go looking at? I've emailed ZZP, maybe I can sort something with testing the PCM.

The only thing you need for spark is the crank sensor, wiring harness, icm, coils, wires, and plugs. Basic ignition is very simple on these cars. If you have no spark, something is wrong with one of those.

Try swapping the stock ECM back in and see if it stays running.
