I cant find the Injector Diagram I'm looking for, but shows Ground distribution, connectors fuse and relay. Duck duck search wasn't too helpful tonite.
A Subscrption or a factory cd manual would be helpful to you. I'll post if I find it. You want to verify power to PCM, and grounds for PCM/injectors. You can test some wiring with above link, especially to/from injectors. If those OK you need new PCM.
