likely to compensate for a worn out ip or incorrect timing i would think (kinda go hand in hand anyway.)
his problem will likely just keep getting worse until he does a tune up.eventually the glow time needed when warm,will no longer work.
did he mention miles on the ip,or loss in fuel economy/performance?

Brand new pump and injectors, lots of power, no excessive smoke to indicate something ain't quite right in the timing department.

Bad Warm Starts

Have you tried adding a few liters of diesel additive for a month or two. It is a long shot, but some IP's manage to recover if they got gummed up.

Overall, I am afraid your IP is the most likely source of your troubles.

Good luck,

Seb....

possibly the fuel solinold in the top of the pump. but if you haven't been running additive in your fuel to make up for the loss in lube in ulsd, its the pump.

i would have sent the pump back and demanded another,after it was timed of course (not just ballpark by ear) and still had the same problem.
his GP system problem while hot only was interesting,but GP's are not needed for an easy start when warm anyway.
likely a poor ip build or poor rebuild.- often new parts sadly, can just be bad.

I always run some kind of additive, but I was kinda thinking the IP myself as well cuz the truck has never been taken care of (blasted oil field).

Didn't I see it mentioned that that truck in question is in Panama? Think the quality of fuel may be slightly different? That it might be something other than the IP?

Pump rebuilt quality is not of any concern in this particular case. Anyways, this is getting offtopic, as that situation is quite unique in both pump and fuel that are being used...

Well, the ol girl has learned a new truck. she'll start great cold, even better than some PSD's, but drive a good 30 miles and grab a bite to eat and its a good solid 30 seconds (not continuous) of cranking to refire.
What the hell is this?
I agree with the IP,.But one quick and easy to check it is to dump a bottle of water on it. If the pump is getting worn the tolerances are affected by heat, (called Heat Soak) So when the pump is at its hottest, it is expanded and wont create enough pressure to supply the fuel, When you dump some water on the pump it cools it down quickly and contracts the pump within tolerances and will fire right up.

Give it a try it may help with your diagnosis.
