    You might have better luck posting this in the Diesel Forum. There are quite a few tech heads in there.

    Assuming that you are talking about the fuel system, try removing the input line to the injection pump and putting air pressure (from a compressor) to the fuel tank through the filler.

    Worked when I did it on a 6.9 F*rd (disclaimer: wasn't mine /forums/images/graemlins/tongue.gif)

    Make sure your lift pump is good, fill the fuel filters, crack the line at the pump. When it weeps, (during cranking) tighten it up and individually crack the injector lines at the injectors while cranking. You'll probably only have to do part of them since they can bleed themselves if the motor will run. If not, bleed them all to get the air out, then the injectors should start firing with no problems.
