    Any ideas on how to fix a truck that starts like this first thing in the morning?

    This is not the actual truck. Just a video I found while trying to find a cure for a truck that does the same thing. It is 35 here this morning and it cranked just like that one above. After about a minute of idle and some foot pedal action it clears up to a light smoke and then you run it down the road and it clears up perfect.

    Rebel this is the same truck I PM you about several months ago. The people have never come to pay bill. This truck has been out of framed and new bull gear, reman head, new injectors, etc.. Ran overhead 3 times. Pulled front cover off to check timing. New timing sensors. I do not know the history on truck or ECM.
    After it gets running for a few minutes everything is clear.

    White smoke can be from low compression, air in the fuel, poor injector spray problems, or low fuel preasure. A Detroit has a cold mode program and should start very easy compared to most every other engine. We found some engines, N14's, started better when on cold mode that when not.
    Just a thought!

    Check your oil temperature sensor...if its going bad it'll throw out white smoke like you're describing. Also the intake air temperature sensor can do the same because it also affects cold starts just like the oil temp. sensor. What I usually do after an overhaul is change all the sensors so you know that you're on a clean slate. Those two sensors should solve your issues. Hope this helps.
