1981 Grand Prix lj v6 no start

I bet it is the ignition module also. It doesn't take much to fry that thing.

in the op's first post he says he has gas and spark, if the module is fried there would be no spark

Could be very intermittent or weak spark. I had this problem on one of mine

it's been my experience that the module either works or is doesn't, a weak coil can give weak spark

OP is MIA hope all is well

Maybe the no start drove him to seek therapy 🤣

Appreciate all the input. I haven't been on or even messed with the car for a while. Got my hands on it again the other day I unplugged the pcm and it started right up. Now question is do I need the pcm to run the car daily? Or can it run just fine without it?

it will run full rich without the computer. and for future reference, it's an ecm. all it does is control fuel mixture, timing advance, and torque converter lockup.

I unplugged the 4wire connector to the distributor and it starts, I plug it in and it won't start why is that . I'm assuming it's the computer, correct me if I'm wrong please
