    At the dealer that I worked at, we had a deisel specialist, and he was the only one who handled these matters (I was in charge of Front end, brakes, abs, power steering, frame damage and that sort of stuff)....but if memory serves, the injector system worked off of the high oil pressure and this would cause the problems that you are describing. I would first start by checking your fuel pressure though. There is no shrader for that vintage, so you'll have to remove the line from your fuel pump to check it. You probably don't have the fitting that's required but if you can check it, the pressure should be around 40-50 psi. Now, if that's fine, move to the high oil pressure pump. There is a PID for this and the pressure can be checked with an NGS scanner. The pump is located top front side of engine under a plastic shroud that's held in place by a pair of 13mm bolts if memory serves. That pressure should be AT LEAST 65psi @ 2000rpms. If you don't have that type of pressure, then you need to check the pressure at the low side oil pump, because if the low side isn't feeding the high pressure pump, the high side will not supply the pressure needed to opperate the injectors.

    Typically, if the cam sensors went (fairly common) it would be a crank no start concern.

    I'll try and contact one of my ol' deisel buddies and see if he can add any insight.
