Problems with 95 LT1 T/A The car was running fine. I drove it around the block and halfway through the drive it just backfired and died. Hasn't started since. Had a guy check it out and he said the PCM was bad. Is there any way I can check this for verification? What can I do and how would I know if the PCM is really bad? Any help would be greatly appreciated.

Sounds like what happened when my opti died. As far as the pcm couldnt you find someone else with the same car and swap the pcm's and see if it runs. Dont know about that but i dont see why that wouldnt work. Maybe someone else will chime in with some better advice.

I was kinda thinking the same thing. I really appreciate all of the info guys. Keep'em coming. I would love to swap PCM's with someone local but unfortunately everybody I know personally has all swapped over to LS1 cars. I used to have a 97 T/A and started having Opti problems a 64,000 miles. I went through 7 opti's in 2 1/2 weeks before I quit having problems. I think it may be the prob but not sure.

ya sounds like the opti died... i was driving down our main street here and i witnessed first hand a opti disaster as a 94 Z28 trailing brown smoke and fuel for 10-20 feet behind it backfired (flames 10 feet back out the pipes) guy pulled off the road i pulled off to make sure everything was ok... couldnt get his car to restart

lol. PCM failure is the fall back diagnosis for all idiots who have no idea what they are doing and only want to make themselves not appear to be complete morons.

I fully understand what you are saying. I talked to the guy who checked it out and and the reason they are saying PCM failure is because they cannot get any codes on the car. They hooked up to the OBD1 port and have absolutely nothing coming out of it. That's why I asked if there was a particular way to verify if the PCM was bad or not.

here in lies the problem. 95 doesn't have an OBDI port. The 95 uses a 16 pin OBDI ALDL, with an OBDI control system. Odds are that they did it wrong.
The best way to prove that the PCM is ok, is to run the tests that I posted and get the car running. During which, when you do find the problem, it will rule out PCM failure.
