So I was going to start my car up for the first time open header before I mount the turbo. Started programming the PCM and it error'd out.

Now it wont prime the pump...well will for like 0.5 seconds then shut off.
Also tunercat or datamaster will not read or write it.

I tried it in another car with the same issue?

Who canI send this to to fix it? Or can i pull it apart and fix it myself?

ITS A 94-95 OBD1

Sounds like you lost the PCM. Thats a bummer. I have gone to Andrew with AKM cables in the past. He's a good guy. If you go that route, have him socket the boards when he repairs it, that way if you ever lose it again, it's a lot easier to fix. You wont be able to fix it yourself unelss you had the right chip de-soldering tools and chip burner. Sounds like your best bet at this point is to send it off and start putting up the turbo while your waiting. I would verify you have good grounds and have good system voltage. Those are the 2 big hitters for frying the pcm. Being that you've been putting things back together, you might have gotten bit by one of those two.

Yea I think when I turned it on I didn't have the battery cable tightened and I wiggled it while it was programming...so that prob did it. My pcm was socketed my buddy said as it was his.
I got one comming from a guy on ls1tech. But ill prob send mine in as a spare just incase.
I guess ill finish my turbo setup this week and start it when I'm done. Hopefully next weekend

If it's already socketed, you might be able to just buy both the chips pre-flashed with a stock program from Andrew and put them in yourself. There is a "T" and "E" chip and each one goes in a specific board in the pcm, so you'd need to make sure your putting them in the right board, but it's easy. You just need to be careful pulling the old ones out making sure not to damage the sockets or pulling the sockets off the board. It is possible to pull some of the sockets soldered legs off the board. Just a suggestion for you. Might make the process easier.
