Maybe change your fuel filter? Where u from only do it when its cold out?

05's were notorious for injector issues, for whatever reason; above included.

Although... I do remember a reflash that came out years ago that helped with the symptoms. How stock is the truck? Has the ECM been flashed at all since the truck was new? Might try an update....

You're not losing any coolant right?

I thought about this too. OP, does the white smoke burn your eyes like partially burned fuel, or does it wreak of scalded coolant? Like D_I said, has the coolant level dropped?

No coolant loss, new tubes and washers and everything torqued to specs

What did you torque the connector tubes to?

What did you tighten first, the connector tubes or the injector hold downs?

Did you vacuum out the injector bores before dropping them in?

Bottom line, if its white smoke its either coolant or fuel in the cylinder thats seeping in there while it sets. If the injectors and the install there-of is correct, you've got a cracked head or blown head gasket. Not to panic you, but there are two very different courses of action depending on the origin of the smoke.

P0251- injection pump fuel back feed. That's the code it through at me this morning. What is caused by this and how can it be fixed?
