Nope not sure how to check the PCM , but i will if i can get instructions how to do it. and if it is the PCM does it have to be programed or just installed since its the OBD1 ?

Thanks

Ehh...not sure about that. I've never had to mess around with OBD1. Someone else on here might know though.

If I had read these codes from my truck I would concentrate on finding out all I could about 513. The PCM has a kind of power conditioner that steps up signal voltage from most of your sensors so that they can be processed by the computer part your PCM. I don't know if that signal conditioner is a separate part, or if that is even the problem. That's just speculation on my part. But after that 513 code is resolved, I wonder how many of those other faults go away?
