Thanks Ed, that's great info.

 

I got my DME and swapped it out.

It is great to have such a vast amount of knowledge on this forum. I hope I can help someone on this forum some day to return the favor. I do help people on the H1 Hummer forums. I am actually a decent mechanic when it comes to that vehicle; they are opposite ends of the spectrum. 0-60 in twenty seconds.

 

Actually, this thread may help someone. Knowing now that you found a ground issue, it will be a reminder of a simple and free troubleshooting step.
