    The problem was found. The constant battery hot wire was corroded and weakened about a foot from the exam inside the harness. It would hold enough current to light a test light but, not enough to power the ecm.

    I had my fuel pressure checked and it was marking zero, not sure how I was running though. Had the fuel pump replaced for $187 from Peterbilt, and now the pressure reads 90.
