Some of this if from a previous post, but it is evolving. (1995 Buick Lesabre 3.8L)

I replaced the knock sensor and cleaned connection in response to P0325, but code still persists. I then removed coil packs and ICM, cleaned the very minimal dirt present, and coated with dielectric grease and replaced. First the car stalled while driving, and won't restart unless it sits several minutes, now won't restart at all. Sometimes it will catch for a few seconds, then die.

Will a bad ignition control module cause no spark? Or will a bad engine control module ECM / PCM cause no spark? Thanks.

Previous post and evolving info could be very relevant. Please link us at least.

I'd help, but I'm tired and not up to the game of searching out your previous posts to try and figure out what'* already been done/tried/suggested/diagnosed as good/bad.

There'* many causes of no spark.

What is that code you listed?
