It's a 00 24v auto it has the banks powerpack system and exh brake.The truck was idleing find and it just died on me tried to start it back up and nothing till the batterys went out,check the fuel filter and replaced it bleed the system and nothing.The LP comes on if I bump the starter theres fuel at the nipple on the vp44.These are the codes that I got Po237,Po253,Po251,Po236,Po252,P1688,P1689 can anyone help I already order a new LP so thats getting replace and also getting a FP gauge, will also get new batts since the ones on there are pretty old. Thankx in advance guys

Thankx I think i might need a VP but I hope it's just the LP.

1688 and 1689 tells me the injection pump control module is gone, replacing the VP 44 is the solution

yeah I just found that on another site too, but I think she still has a chance i'll wait and install the new lp once it gets here. Has anybody tried to rebuild their own VP yet???I was thinking about it looks like could be similar to a turbo rebuild.

you cannot rebuild your VP, unless you have their 100,000 plus $ test bench.
here is a really useful link to blue chip, which helps diagnoise your VP, The electronics are gone on yours, could be caused by low/no fuel pressure as the VP is cooled by fuel (just a guess)
