I am not sure what to do next. I am really confident that my tractor will start if I can just get fuel to it. I don't know whether i am failing and getting good prime in the fuel system or if there is something wrong with my injector pump. Here is what i've got so far:
-Clean diesel
-Flow from tank to filter (brand new filter element)
-Good flow out of filter and have bled the fuel filter according to IT Ford Manual.
-I have disconnected fuel hose leading from the filter to the injection pump at the port on the injection pump. The fuel hose is clear....so i get a great stream of fuel thru the hose and then shove it onto the port on the injector to avoid air bubbles.
-At the advice of TXJim i loosened the two screws on the timing plate cover on the pump and got good flow from there.....then tightened it back up.
When i crank over the engine, i can see an airbubble form at the fuel hose as it meetings the pump. I loosened the injector lines where they go into the head and cranked the engine over for a bit, but didn't get prime and didn't see any fuel flow out of the injection lines.
Two questions:
1. How do i know if I'm just not priming the pump properly or if I have a bad pump?
2. When i crank the engine, is there any way that it could be sucking in air from return line to the fuel tank?
