    You are correct about possibility harness problem
    But when I change injector
    Harness good for year time and then start do the problem
    Fuel mileage on truck good
    No oil no coolant consumption

    Unplug ECU and see if you got oil in it. Very simple job and you would eliminate one thing.

    I don’t now about connector at cylinder head on this engine
    Wires going from head to computer without any more connection
    If I am correct
    Engine d12d
