check your LP pressure.

Add a lift pump and some sort of fuel pressure gauge in the process. Your VP44 will be next since it's probably starving for fuel. Let me know if I can answer any questions.

Another thought.
Batteries.
These are the originals. After running and idling all day, the truck starts fine. 1st thing this morning and when cold it really struggles before it finally kicks in. I may as well look at a lp whether it is the batteries or not I reckon. Does mine have the in tank one or is it already outside?
So, do you think new batteries will solve today's problem?

03 is outside tank and sounds like lift pump getting weak

I knda understand the lp thing, but I thought that the lp worked or it didn't????

no they can slowly die, which will put more strain on the vp44.

Also check the rail pressure relief valve. It could be bleeding off pressure after shutdown. Had a bud with an '03 with the exact same symptoms. He wound up just retapping where the pressure valve was and put a plug in there. That solved his long cranking, no start except with ether problem!!!

is it on the 03 in his sig it would be CR not vp
