    Thats just a cecu programming fault. Means nothing. Can you see engine hours on the dash?
    Type of truck? Year? S/n?

    Did you get the motor washed? [big no no in my book!]

    Pull the wiring harness off the ecm [tge OEM harness], pull up the wiring diagram for your motor off cummins quickserve . Com

    See which pins are for 12v ecm power supply, test the "holes" in the wiring harness plug with a multi-meter for voltage with the key on.

    If no power then, you need to restore power some how

    Turbos seized in the full closed position restricting exhuast flow so it wont start. Pull the vgt actuator and check travel of the vgt. Probably needs new turbo and possible actuator. Not common, not unhead of for this failure to happen. Usually has no codes as well. We have seen a dozen or so of them.
