So another update, shop is still having a hard time.
They’re trying to get my ECM connected to a scan tool, and the ECM seems to not want to communicate with their tool. Odd right?
The ALDL port did work I was always able to use a paper clip to get codes.
Think the ECM is going bad?
By using a paper clip, did you deform the terminals enough that the shop’s ALDL mating plug isn’t making good electrical connection?
I won’t say it’s likely, but I’ll say it’s possible… depending on the size of paper clip you used, of course.
There’s nothing wrong with exchanging the ECM with another one, all that’s lost is some money and some time. I don’t think that the problem lies there, but I’ve been wrong before.
I think you’ve got some other things that need to be taken care of first that are obvious, such as the ground between the frame, the firewall and the engine.
Reflect on the story I told you in my earlier post. I’ve seen lots of people beat their heads against electrical problems and come up empty-handed. Many people just aren’t very good at debugging such things, lacking either the tools or the experience.
