There should be a couple of grounds to the car's ECM. Where are they? This last week my Trans Am died and I am not getting any codes from the computer at all. I have power to the starter fine.

I have a feeling that I may have an electrical short somewhere. The battery has been draining pretty quickly. Last week when the car died, I was able to get it going again. I am not sure what happened, but everything was fine. Now I cannot get anything.

I thought it was the ECM that had fried, so I repinned the harness for a 730 ECM (which I have two of them), and neither of them are giving me a code 12 either. I am at the point now that I am pretty sure its an electrical issue.
