OK this is a continuation of this thread
HIstory: I got truck with one deadcylinder but the truck still fired and ran. all injectors were good and the IPR was not held on by the nut.
here are the updated thingsi have done in total.
Rebuilt engine, replaced CPS, ICP, Fuel pump and lines, and injector o-rings.
I cleaned the IPR out, and the FPR, cleaned all of the connections on all connectors. I have cranked it countless times of 30 second bursts. The oil galleries are full of oil the HPOP res is completely full (all the way to the top) the fuel galleries are full as well as the fuel bowl. The GPR is good and tried using block heater. the glow plugs are good. Base oil pressure is NOrmal.
I also converted the hard fuel lines that go into the back of the head to a compression fitting using feruls.
The EBPV sensor conector is broken off. would this keep it form starting??
The only other thing I can think of is the HPOP is not moving enough oil, but I dont have a scanner so I am unsure of the actual oil pressure after the HPOP. The programmer (99-00 7.3 Hypertech just used for scanning codes) I have says that there are no codes. The cylinders are not getting any fuel as the IDM is not firing up Is what my gut instinct tells me is a lack of hi pressure oil. The fuses and relays in the fuse box are good. I never touched the IDM or PCM during the rebuild so I doubt they are suspect. I can feel it that it is something stupid keeping my motor from firing. please help if you have any suggestions, as this hads drawn me away from keeping my business going. I am not only spending money on parts but I am spending my work time trying to get this thing running.
