    You cannot reset codes without a proper scan tool.
    Ok, not interested in climbing up the wrong tree. I would get all the codes cleared, then run it so it logs fresh codes and go from there.

    Need find someone who has servicemaxx or NED software to hook up to your truck. Will have a better idea of exactly what’s going on. I.e run test, see live data, verify active and inactive codes.

    Truck was scanned and cleared. No codes come back except ac codes which is odd. Anyhow Fuel pressure to the rail averaged 74 psi and called for vs delivered rail pressure is right on par. Only fishy thing is throttle position remains at 0% during live scan no matter pedal position, but the engine does rev up and down by the pedal, it will run no longer than about 10~20 seconds before shut down. It'll fire right up and sound healthy. Just will not stay running. I have no clue what to do next.

    I've seen exhaust, air to air, or the intake heater grids so plugged it will starve the engine of air.

    I have started it with no intake tube on, it nearly sucked my hand in the throttle body at an idle. I could feel some air from the turbo but not like my supercharged cars at an idle
