    Do you have any idea, how I can have lost both fuel and oil pressure overnight. All I did was clearing the codes on the dashboard in the morning. Day before truck was running perfect for 80 km

    Fuel pressure is back. Only oil pressure is still at zero. Last time the dealer mechanic played with some wiring and the power feed fuse. Can it be something else

    Oil pressure sensor is below the high pressure pump in the block. Maybe there is loose connection.

    The instrument panel gets all the engine data through the j1939 data link. Does the tachometer and the engine temp gauge work?

    Don't run the engine until you know that there is oil pressure.
    Hook up a gauge to it somewhere to check the pressure.

    Just so you, if the engine cannot make base oil pressure, the high pressure oil pump won't get oil either and it will never run. One good thing about these. No oil pressure, no start.
