IP Fuel Problem Stalls New m35 owner

[turnerman]

HELP!! Brought new m35a2 home not running. Found the IP head retainer clips and return spring floating in the pump case. Put everything back together and the truck fired right up, but when you load the engine as in normal driving it stalls. Smokes grey all the time but when accellerating black to brown. I have verified timing and installed new fuel filters. Anyone have Ideas?

Air filter, turbo, injector, high fuel restriction or no in tank pump working, a failed fuel pump?

Removed air filter, non turbo model, removed injectors all clean, installed all three new fuel filters, in tank pump builds up pressure. Even will idle with the in tank pump un plugged. I guess I will remove the ip and let a pro look it over. I was hoping for an easy fix. How much are Injector Pumps now?
