P Pump Problems
hi, I have a problem with my p7100. i have feul to the filter, and to the pump, but the pump does not create pressure to the injectors. Also the shut off seleniod is fully up. Can you guys help me to figure this out? ---------------------------------------------------------------------- '94 dodge 2500 4x4 , 4" exhaust, pyro & boost gauges, 35" bfg's

The relief valve is closed and it works. When i pump up the the pressure with the lift pump it makes a squeeking sound at the relief, that tells me that its working. The part i don't get is that i parked the truck running, found out that one of the tubes on the pump was loose, so i tightened it, and now no fuel pressure to injectors. i htink i'm missing something small but i can't quite figure it out!!is it a blown injector pump ?

One of the tubes was loose??? Was it #5 injection line that was loose? Pull the AFC housing off & see if you can move the rack. The reason I asked if was #5 is because on the 94-95 pumps had an issue with #5 splitting & causing problems.

wow thats right!! #5 was loose and i took off the afc housing. the rack did move with some force, but i think that is not right! What is the fix on this? Thanks for the info!

pumps gotta come off. Look for a good used one, I just sold a 1997, 180hp for 1k outright, I'm sure there's some more kicking around. If you can find a 215hp, came in 96-98.5 5spd trans, that's the best pump to get. Look at the tag on the side of the pump, Bosch # 0 402 736 913 or last 3 digits can be 887 are the 215hp models. Fixing yours is an option, but because of its lack of performance, I'd suggest getting a later model used one.
