[QUOTE="rdnkbowhuntr, post: 1348906, member: 13528"] Assuming the IPR is good since I am showing 12V with keyon. And applying 12V directly to the IPR allows the truck to start. CPS plugged or unplugged doesn't matter. I traced continuity from the IPR through the 42pin at the left valve cover and through to the PCM, it's all good. Viewing the PCM through the OBD port it is showing default 14% at key on and climbs to 67% while trying to start. The only way to get the truck to run is fully close the IPR manually. I am showing good pressure on both heads and the pump. I'm stumped again. [/QUOTE]
