If the o rings for the injectors were that bad, that still doesnt explain why the low pressure pump wont fillt he resevour on its own after cranking.....Yes a very bad injector o ring situation could cause a bleed down, but it would leak into the fuel system. If the gauge wont register even when running, that tells me that either your sending unit is bad or that there is in fact low oil pressure, which would make sence..... Have they run a manual oil pressure check on the truck with it running??? The only other common reason for oil pressure to have problems, which would explain all your symptoms, would be worn main bearings......
How many miles on your rig agian???
