Swap in a known good ECM and report back.

I believe it a wiring harness problem you said you have some pin problems.

Took some offline advice and changed the crank sensor.

save that part the only relationship it has to your problem is its 2 feet from the ignition module

Rebuilt Delco pcm from rock auto is in, problem solved!

No idea how that was possible, never hit bad pcm on the tree with any parts. But hey, now I have a few "known working" parts laying around

I let it run for 10 minutes or so with no codes, we'll see how it runs when I have the time to take it out for a spin.

Thanks for the help everyone, this forum is great.

Make sure to take it for a long drive. The pcm in mine always failed after the car was driven 20-30 miles. Hopefully your issue has been resolved.

Took it for a drive tonight, maybe 30 or 40 minutes. Didn't get a CEL and the car ran great.
