Well, I have been trying to get a new or remanufactured ECM for my car to fix the problem I have with no signal to injector 1. Now I have a new problem. The ECM has either been changed before or came with the wrong one from the factory. I am betting on the former. It has the wrong ECM. Nobody will swap it, so I have no choice but to pay dealer price for a new once, since there appear to be none in junk yards that I can find.
