I stalled my engine while pushing snow. It won't start and I have no fuel presure at the injector lines. The tank is full and fuel filters are not clogged. It is a Ford 1700 with Shibaura 2 cylinder diesel. Any ideas?

It sure sounds like fuel dump valve or solenoid is stuck open.
I don't know about your particular model, but if it has a push/pull cable-style kill knob check it's all the way in.
Also check that the solenoid that dumps the fuel when you shut the key off is actually getting power. A poor ground is a common problem. The solenoid itself can also go bad. If you were pushing snow it could be something as simple as a wire got bumped, or as tough to find as a frozen (engine heats melts the snow to re-freeze) fuel dump solenoid.
Best of luck.

Or it could be something in the operator presence system that is cutting out the solenoid. My New Holland used to cut out when I side-hilled. Turned out I was rolling my butt to one side and lifting off the the seat switch.
I'd check the seat switches and the like. ....

This little diesel is not that fancy. There are no cut out switches or anything electrical in fuel system. I've determined that the pump is not operating. Does anybody know of a good overhaul shop for diesel Kiki pumps? ....

So to stop the tractor you have to do something, either there's a solenoid ooked to the key switch, or a push / pull cable like an old style choke setup.
Be sure that's not the culprit first.
Injector pumps don't just go out like a light bulb, they fade away very slowly after a LOT of hours of use. I've seen them go 12,000+ hours no problem.
Best of luck. ....

You say there is "no pressure at the injector lines".
That may be, but you didn't say if that was due to the lift pump gone bad (which is highly likely) or the injector pump is bad (like Murf says isn't likely). And if the lift pump has gone bad, chances are the engine oil will have fuel in too if it's NOT an electric one. ....

Ok...good info..thanks. There are no switches or solenoids in the fuel system. No cables. You push the throttle lever to stop and the engine idles down and stops when working correctly. there doesn't seem to be any lifts pump. The tank gavity feeds to the injector pump/governor (diesel Kiki 13101) and from there to the injectors. I have good fuel supply to the pump, nothing at the injectors. I suspect there is problem with the governor part of the pump. In any case it is not allowing fuel to the injectors. ....

Two things:
1. Does it go through a filter or sediment bowl before going to the injector pump?
2. Have you checked the fuel filler cap's vents are not plugged? If it doesn't vent ot atmosphere that will create a vacuum. ....

It's running!! I took the injector pump apart and found an old washer that was jamming the internal governor linkage. The washer belonged to a linkage shaft that must have been worked on once. It must have fallen into the bottom of the housing. I fixed it, put the whole thing back together,primed it and it runs great. You guys really aren't much help are you....just teasing...thanks for trying. it's kinda hard diagnosing a problem from messages. ....

That's because you did it wrong. You're supposed to give us the answer (Loose washer in injector pump) then we would come up with the question (why won't my tractor run?)
:)
Congrats on fixing it, and thanks for the follow up.

Makes me think of "Car Talk" on public radio.
Glad you got it taken care of. ....
