m6800 starting problem

williams	A friend's Kubota m6800 has developed a starting (or running) problem. When the ignition switch is moved towards the "start" position, a solinoid on the rear of the injector pump starts a very rapid clicking sound. If the key is continued to be turned, the engine will crank and run briefly. To get the engine to continue to run, the key can be held between the "on" and "start" positions(I'm not familar with the tractor, is this the "glow plug" position?) and the engine will run, but the solinoid will be making the rapid clicking sound. Any help on this? thanks for any help
Butch	The clicking I think is the fuel shut off valve. Holding the switch in the position to make it run is suppling current to the shut off valve. When you let the switch go to the run position and it dies, is because no current is going to the shut off valve. You may find a switch problem or fuse blown, and also could be a wire connection at the switch. Just my guess, maybe this will be a start for you.
williams	butch, thanks for the reply. I'll try to check out the circuit, mw
