It seemed like it was better for awhile then it happened again. But at the same time the car has done that before without replacing parts. It will randomly work for a few days without issue or even weeks. Then come back again. It did do that when I replaced the icm once and I thought I had fixed it. Then the second time it seemed like maybe it did for a day or two but then same thing. Its so intermittent that I really cant tell. I have another junkyard ICM that I havent used yet but I also have been running the car randomly in my driveway to keep the battery good (already killed one battery and now have a new one) and not had any issues with it dying so I wouldnt know by replacing it right away, then again if it happens again I wouldnt know if its because yet another faulty junkyard part. A new one is $250+ and I dont know of any reliable online parts stores that are safe, it seems all the ones on ebay are un-reliable parts. Its only $10 at the junkyard.
So I guess now my question is. If there is no spark (once I have this established as I believe this to be the problem if not fuel pressure that I have no way to test especially when randomly only dead for 10 minutes) is this the only possibility? Is there any other thing that could cause this issue? Could the computer cut the engine off for any reason without popping a code? Or could the computer (pcm whatever its called) overheat? I must establish im no master mechanic by any means im self-haynes/chilton taught with minor help here and there. I would just like to know all my possibilities.
If its no spark is the ignition control module only possibility?
If its bad fuel pressure is fuel pump able to die only when hot and then only work again 10 minutes later? Or can the pressure regulator have that issue?
Im down to these are the only 2 possibilities and im pretty sure its spark but wont know more till later but the issue isnt just gone so id like to stop poking in the dark and know the only possibilities
