Need a little diesel help in Gwinnett
Anyone willing to help me diagnose what's wrong with my 6.0?
It seems electrical.
Background on me:
I design/install/support automotive controls for a living... but for GAS motors. Diesel is a new & foreign game for me.
Truck is sitting at our shop in Suwanee right now. Runs like a bat outta hell on 8 cylinders, or it runs on 6 cylinders and can't get out of its own way, based on its own whimsy. I have an EDGE Insight CTS, and troubelshooting tools like scope and DMM, but not specific diesel tools.
Many things have been suggested, but I'd like to attempt to properly diagnose instead of just throwing parts at it.
One possibility seems to be a logic failure in the FICM. If someone had a FICM I could test in my truck, or test my FICM in your truck, that would be pretty awesome.
