I say the GP's are not the problem. I have started my truck in the winter in Idaho w/o waiting for the GP's... I would say you may not be building enough ICP when cold. The white grayish smoke is clean unburnt Diesel that did not have a chance to flash burn in the hot exhaust. It could also be a compound situation.. Worn Injectors, tired HPOP and compression.

I have the same deal as you're describing. My '02 has progressively been getting rougher and rougher in the cold mornings. I have a Inj code floating around as well as a leaky IPR and a questionable ICP at start time. I have had a scanner on it in the mornings and it seems like it needs a few turns to get everything in order. I am replacing the IPR next weekend due to the leak. I am also going to look at the Adrenaline HPOP and a set of singles soon.

How many miles do you have on her?

I take it you mean a slow crank? If so, how old are your batts? These motors can do funny things when the batts are on their last leg.
Best,

If you have access to a scanner, you can look at ICP during cranking. But, based on the fact you see white smoke rolling out of your tailpipe during cranking, your injectors must be working which means you must have enough oil pressure.

It may be your GP's.. Do you have any dtc's or have you hooked a scanner up to see what comes out?
