After that, have someone crank the engine while you push the shrader valve on the fuel filter head in until fuel comes out.
Next, you need to check the fuel shutoff solenoid on the injection pump at the top center of the engine. The thing all the hardlines are going into. You need to put a multimeter on the fuel shutoff solenoid connector checking for 12v when the key is turned to "on". If you listen to the pump while someone turns the key to on you should hear a faint click. If you get 12v when the key is on, continue on.

Final step, crack the hardlines and crank the engine until fuel comes out. If you reach that point let us know cause then we will tell you how to bleed it. If you follow those steps your either going to find your fuel issue along the way or it's going to be something like a bad fuel shutoff solenoid or pump component.
