My truck died after I put the pedal to the floor
Well I had a problem with my airdog fuel pump a couple of months ago that left my truck stranded but I got that fixed. I think it may have damaged my vp though in the process. I pulled out of a stop sign and it was fine then I put it to the floor and it just flat out died. I checked the fuse and it's fine but when I go to start it I can tell the pump ran dry but I can hear the airdog kick on. If I crank it long enough it will start but it sounds like it's just enough to keep it idling but it's rough as hell and no throtle response.

I know, I know about the gauge but I really haven't had the money for it. I guess the damage was done when my airdog went out on me before.
I rented a scan tool and it came up with P1688 so I'm guessing I'm SOL. Its strange that my truck just died with any hesitations before this. I drove about 30 miles then I pulled out from a stop sign and it was fine but 10 seconds later when I put it to the floor it just died.
I cracked the injector lines and fuel was coming out when I bumped the key but when the truck did start it barely ran.

Time for a new VP44 I'm afraid...

I was reading on the Blue Chip Diesel website that its probably the module in the VP that fried not from low fuel pressure. Whatever it is I still need a new one.

Don't know. If you have a later model '01, you may have the same issue I had with the VP44 on my '02 on which the bearing sleeve seized up. I hear it was a common problem with them...

VP is shot for sure, sounds like you are lucky. Last one we had where it stalled after full throttle the VP siezed up and the customer was out a pump and lost the core charge as well.
