Ok so I hooked up a power programmer to my 96 caprice lt1 and my daughter pulled the cord from DLC to soon and my car wouldn't start so I called my friend who had an extra pcm so I tried to program that one but it wouldn't let me so is there a way to reset my old pcm or is it done all together

It's probably toast, but give it one more try after it's had power disconnected for >30 min or so.

IIRC if you are using a Power Programmer, it memorizes the VIN on your PCM that isn't working right now, hence why it wouldn't program the other PCM, hopefully your original is ok, or you will be out a programmer and a PCM
