    On the smoke deal those DB2 pumps did tend to get tired/worn and sticky in the advance bore. The tendency was more toward a blue/white smoke coming off idle. Getting the lift pump working is an important first step.

    Wastegates on these models tend to stick closed if anything. The fact that it moves at all is a sign that all is well. Boost gauge mandatory for diagnosis.
    Ok thank you. I just order a new LP harness to see if that gets things moving. I’ll looked in to a boost gauge as well

    I didn't realize how bad my 6.5L was blowing white smoke upon start up until putting in new glow plugs. It had slowly gotten worse over time without me really noticing, but now there's very little white smoke at startup with the new plugs.

    New glow plugs install. White smoke it’s not a problem anymore. The glow plug harness will need replace
