Im getting code P0251 and P0370,I know they are the codes of death for the IP,I changed the pump with one from a running motor,Im wondering if bad injectors would cause the pump to throw up these codes,I cant get this motor to start,Ive bled the filter,got 7psi on the lift pump and a clear steady stream of fuel out the drain coc at the front of the motor,when bleeding the injectors, I don't seem to be getting fuel out of all of them almost as if some of the injectors are stuck open and not creating any back pressure

 

Have you checked your fuel shutoff solenoid, even if it worked before it might be losing contact somewhere with the new installation or might have just gone bad, might try swapping it with the one off your old ip I've had one develop a bad connection where the wires enter the housing of the fss

 

It takes a while to get fuel flow to all the injectors.

Best method is to pull the glow plugs and crank the engine with no compression until each glow hole fog's fuel.

Put the glows back in and start it up with 1 injector line left loose and tighten once running.
