Yeah, I bared all the wires going into the power distribution box and into the ECM.
found no breaks, but did find a “funky” looking fusable link so replaced it. No help. The power wire that goes into the ECM is red with a white stripe. But the wire out of the Power distribution box that is red with white stripe is hot all the time. That is where I made the splice and ran a wire over to the dead wire at the ECM. The truck runs like a champ.
Still don’t know what went wrong.
