<ok im an idiot the wire to the starter was loose - cranks and runs -that was untill i ran it out of dieselhow do you prime a 6v92? keep cranking?>Not unless you want to replace the starter again. Try filling the fuel filters and then try it. If you cranked it after it stopped you will probably have to put some pressure to the system. I recommend an inline fuel pump. Makes priming a snap when/if you run out and makes changing filters a snap.good luck
Don Fairchild NEVER uses a primer pump-he says it is to easy to blow the pump seals.
