deadheaded hpop to test, it gets 4600 psi while cranking, but immediately drops to 0psi as soon as cranking stops. ipr is new, and commanded close manually with 12vdc applied to pigtail.. what do you guys make of that?
problem is 333 code when under load or climbing long hills. Icp, injectors, and o-rings are new as well, starts right up whether sitting for 4 days, or hot.
charged oil rail through pop input, left icp in place(didn't have fitting to charge through icp port) plus I figured charging through hpop oil rail inlet, would eliminate the need to command ipr closed. I just used ball valve between shop air and oil rail to see if it would hold any pressure, all the pressure bleeds off in about 10 -15 seconds, and I don't hear any air bleed off.. no oil in diesel, or vice versa.
engine does idle a little rough, new cam sensor(aftermarket just for testing purposes)
Whats you guys opinion? was told that hpop should slowly drop pressure after deadhead, and not just fall off immediately |

deadhead test results, not sure what to think
