We got this tractor new in '92, I think, and I've had to bleed it several times (my dad was bad about running it dry). A few weeks ago it quit and I thought I ran it out of diesel so I put a few gallons in and bled it. It ran fine for a few hours then died again so I put 3 more gallons in and bled it again, it ran fine while I finished plowing.
Two weeks later I tried to start it in the shop and it wouldn't start so I decided if I was going to bleed it again I'd change the fuel filters. I assumed it might still have some air in it. I changed the filters and bled it and it ran fine for a couple of hours. I was pulling an 8' shredder Saturday and it started speeding up and slowing down about 100 rpm every minute or 2 and I could hear it pop periodically so I knew it must have some air in it. A few minutes later it died.
When I tried to bleed it I got good pressure on the bleeder port on the low pressure side of the injector pump but nothing at all on the high pressure side and nothing but bubbles at the injectors.
Sorry for the long story, here's the question - is the injector pump dead? I also noticed I developed a new oil leak that might be the fuel pump, I didn't track it down yet but even if it's leaking I had plenty of pressure on the input side of the injector pump so I assumed it should at least let me bleed it.
Any ideas?
Tnx,
