    My Detroit has been one of those with the white smoke at startup. Well today I did something different. And only one small puff of smoke at startup. I hit the fuel before turning the Key. Then hit it while turning it over. Fired right up, ran perfect. And that one small puff of white smoke.
    Buddy of mine told me to try this yesterday. That they had lots of them do this when cold. But if he did the above. Almost no smoke and ran great. Mine also stumbled some at times when first started. Then smooth out and run good. But today no stumble, idled perfect and no embarrassing smoke. :eek:
    Will try it the next 5 or 6 days. And see how it works out then. 23 degrees this am and it worked. Hope it keeps working.:D

    If you think that's embarrassing, you should see my 3406e fire up when it's below freezing. Personally I love that smell!

    We have a FedEx terminal behind the tank wash I park at. I fill their entire parking lot with smoke if it's cold and the wind blows out of the West. :D

    Thanks guys, I don't mind a little smoke. But this truck is King. As in Block out the view for a few minutes.:mad: This am it was still smoking. Not as bad,but still bad. It being a weed burner makes it look bad for sure. Will try to get a Video next week of liftoff. ;)

    I have some 10K Resistors on the way. Going to try one of those tied in the white wire. Read a few that did that, issue gone. And buddy of mine told me Friday he has done a bunch like that.
    He was out of them also, so ordered us a bunch. Got 100 for what a 3 pack here would have cost. Then had to pay shipping. Because where in the middle of no where.

    Never take anything you say for granted. LOL Unplugged it and almost no smoke. And get this, Fuel gauge is crazy from Empty to showing what it should.
    With the IAT unplugged, it showed 3/4 Tank 350 gallons. So looks like that is tied into the fuel gauge also..
    And ran a new Coax cable for the CB. In the Overhead, and now feedback from Both window motor, Blower mower, Both Mirrors. Guess I will take and redo that job also.

    Thanks for that unplug ideal. 10K Diodes should be in next week. Will use one on the white wire. And later on when I get the truck ready for the road. Will have all the info on the ECM checked. I bet being its a IV and it had a III they did not set the stuff right for the engine.
