A very long winded story short... I have a JD650 2wd, it has been sitting outside for at least the last four years. Brought her inside, removed the fuel tank, drained the junk from the system, completed cleaned, refilled, and primed. Cleaned out the intake, cleaned the intake heater, did a valve adjustment just to be safe (not much adjustment was needed). Put a new fresh battery in it, new ground cable. After all that was said and done, I went to start it, it seems I am getting good compression. At first when trying to start it puffs smoke and wants to take off, then it peters out and just cranks indefinitely like Im not getting fuel. Went back and cracked the lines at the injectors, hardly drops coming out. Rebled the system to be safe, same result again. Pulled the injection pump thinking maybe I had some gunk in it, or a broken or seized spring. Nothing. Everything seems fine inside it. Put it back on, reprimed again. Same result. Took the lines completely off downstream of the injection pump and when I crank it over, only droplets form at the top of the injection pump. Hardly enough in my mind to do anything. I expected geysers of diesel to shoot out of it when I cranked. Suggestions, ideas? I dont want to just instantly condemn an injection pump. I have rarely seen them go bad, and when they do I usually see that diesel leaks out the back and into the case and thats where your pressure goes. But this one is baffling me.
