I need some help getting a mid Eighties Long 460 diesel tractor (Fiat engine) running. We are pretty sure it's a fuel issue.(Note: I am not a mechanic)
Note: It was my Uncle's farm tractor, (he passed away about two years ago). The tractor cranked and ran good the last time he was able to use it. Since then it has been sitting for over two years. I got it started bout a year ago, ran bout 30 min and quit. Got it cranked a week later, ran bout 30 min and quit. Since then, No crank and No run.
Things we have done: drained the fuel, flushed the tank, replaced with fresh fuel, replaced the lift pump, replaced the fuel line from tank to lift pump, removed and cleaned all fuel lines, removed injection pump and had injection pump rebuilt, replaced both upper and lower fuel filters.
I now have everything back together. I started bleeding air from the system, using the manual lift pump, got both lower and upper fuel filters bled out. I got fuel to the injection pump lower bleed plug, but not to the bleed plug on the upper side of the injection pump.
I have NO fuel to the injector lines, tried using manual pump and tried cracking engine over to let injection pump work, still no fuel past the injection pump. Note: I had injection pump rebuilt, then later had it tested at a different shop. They have assured me, the pump is not the problem.
Any ideas, thoughts or suggestions?
