Looking for some advice on this unit. Some history might be in order. I owned this tractor about seven years ago. Ran fine. Sold to a friend of my father-in-law. He used for about three years and one day would not crank. It has been sitting for about four or so years now untouched. I loaded it up and brought it home to try to get running for him. Tank was rough inside, glass bowl was full of crud, primary pump was plugged up. Basically I've had to remove every piece between the fuel inlet on the tank and the injector pump to blow/clean out. New fuel is now getting to the injector pump and bleeds OK. Will not crank. Removed compression nuts and no fuel is getting to the injectors. Cranked over for 10 or so seconds several times. I hit another thread where another subscriber removed the cover on the injector pump to find that the stop lever stayed in the off position due to a problem with the connecting hardware. I'm ready to try that this evening. One other interesting note. The bottom bleed screw on the injector pump bleeds at a slow steady rate when removed, kind of runs down the pump and drips onto the ground. The upper screw sprays out several feet upon each pump of the lever. Might be a factor. BTY - I'm not a mechanic by trade but have turned a few wrenches in my time. 98% of which have been on gas thought. Very little diesel experience. So here's the question.

1) What else could cause no fuel to the injectors when the pump is full of fuel other than pump failure.

When I get it running I plan on replacing all filters, fuel pump, having the tank cleaned out etc... Basically getting the fueling system back in top order. Would like to hear it run first. Thanks for your help.

Might have to keep bleeding it at the injectors. I have seen the kill cable get stuck like you said before also. You might also need to check the compression.

The lines from the injector pump to the injectors may be clogged. If you have fuel at the pump ports then the lines need cleaning too.

I've also hit on a couple of threads about possible strainers in the fuel tank and the injector pump that might be clogged? Of course in this case as fuel is getting to the pump it would not be a fuel tank strainer. Also removed the line from the injector pump for the most forward injector. No fuel leaving the injector pump. Has to be related to the pump somehow. Fuel getting in. None getting out.

Sounds like you have zeroed in on the problem, hopefully it not going to be a big deal.:)

Is there a strainer in the injector pump?

Sounds like u will have to have the pump worked on. I would have a dealer work on it since it will have to be timed when going back on. Bad thing is that it could cost any where from $300 to $1200 depending on what they find.
