2002 7.3 Long Cold Start and White Smoke Help!!!

[mrwizard116]

Hey guys I'm needing some help here, this is the first Powerstroke I have ever owned so please bear with me. I have been around diesels most of my life, my father had 2 Kenworths and 2 Freightliners, 2 with Detroits, 1 with a Cat and 1 a Cummins. This Powerstroke is a different beast I'm sure you can all agree. I have taken a video of this mornings cold start, at 34 degrees, it should have started ok but this is ongoing, every morning no matter if it's 34 or 45 it's the same thing. Hard start with lots of white smoke. Sometimes throughout the day I go over the 2000 RPM range it feels like it's stumbling a bit. Is the engine just tired? Do I need to replace things? Hopefully from the video you guys can help me diagnose this problem. 2002 Ford F350 Cold Start Hard Start and White Smoke Need Help!!! - YouTube

Sounds like you batteries are strong and the gp system is good it sounds like it has a bad cps. You changed the gpr? Maybe test it to be sure its working correctly.

Ok just watched the entire video. Could be your uvch they like to work themselves loose and create rough idle and starting conditions the cps wouldn't let you start it if it was bad but it could still be a suspect. Those injectors sound beat up.

Yes it has the new GPR and a new Fuel Pressure Regulator. CPS as in Camshaft Position Sensor or Crankshaft? I have a great local diesel shop if I can't get the answer here, but I don't have a lot of money to throw parts at it. The guy who had it before had the valve covers off and said there was some issues in the harness on the passenger side. Didn't say what issues they were, it starts fine when warm, it's only the first start of the day that I'm having trouble with.

Camshaft. Check both batteries and voltage to gpr. Check the hpop and the icp sensor I would start there its easy stuff when was the last oil change make sure the oil in the hpop is clean and up to level.

Unplug the icp and try and start it if she fires up your icp is bad

I will unplug the ICP in the AM and video it to see if starts. I just serviced the truck with Rotella T 15w40, I don't think the guy who had it before took great care of it, so we can rule out old oil. I'm clueless as how to check the HPOP if you could give me some insight on that.

Do a cylinder contribution test, you most likely have at least one injector that will fail that test.

Also the colder it gets outside the harder it will be to start. Eventually you will have to plug in the block heater to start it in the morning even when it is 45 degrees outside. All the whitesmoke is unburnt fuel that is cold.

Living in Michigan I know about cold starts.

Just trying to rule things out. Hpop has a plug on the top drivers side just under the powerstroke plastic cover on top of the motor I believe the oil should be about an inch from the top. I agree with the above post you have at least one bad injector. I still wouldn't rule out the cps.

45 is warm you shouldn't have to plug these trucks in until 15 or below. I never plug my truck in until it gets to 10 she fires right up with remote start at 10 no problem.
