MF 175: unable to get fuel to injectors

Hello to fellow Massey Ferguson owners. I recently purchased a MF 175 with 150 hours on a rebuilt Perkins diesel engine. The seller told me that "all" I needed to do was re-torque the head bolts, since 150 hours had passed since the rebuild. I drove it home and it was a gem to ride. So, I mounted the tank on a frame 2 feet above the engine and connected the fuel lines, and the tractor ran with that configuration. Then, it sat for 6 or so months while I worked on a "honey do list". Alas, when I returned to continue the task, the tractor would not start. Turned over just fine, but no fuel to injectors. Bled the filters and the top and bottom fuel pump--no fuel to injectors. Today, I detached one of the injector fuel lines at the pump, and no fuel comes out when I turn the engine. Same with the other three. HELP. I am frustrated.

Likely some of the pump internals have stuck from setting. Did you leave the shut off pulled to the stop position while it was setting? What type diesel are you using? plain or bio-diesel?
 
Sounds like the rotor plungers and/or the metering valve is stuck. ANY traces of water in fuel, or Bio diesel will cause this trouble. I see this often on pumps in for repair.
 
so is there fuel coming put the two bleed screws on the injector pump?
Thank you for responding. I have the tank up on a frame about 18 inches above the valve cover. When I open the injector pump bleeds, diesel flows out freely by gravity without cranking engine.

I do not remember position of shut off while it sat. I am using plain off-road diesel.
