Hey Fellows, I need some help finding out the problem with Bobcat 337 not starting, it cranks. Just before I had to choke it down to shut off. Found out the linkage in the fuel cutoff solenoid had come out. The gauges will not lite up, I screwed the linkage back in the solenoid, still nothing. Got good power to starter. Could the solenoid circuit be open, if it was seems like the gauge lights should still come on. I disconnected the neg side of battery hoping it would reset computer. Still nothing. Thanks

You have to figure out if the solenoid is working.. just remove it out of the way and loosen the lines at the injectors.. crank the engine and see if you have fuel to that point.. if not, your pump isn't pumping..
Go to the injection pump inlet.. loosen the inlet connection.. crank the engine.. do you have good fuel flow TO THE PUMP inlet.??
It stands to reason, if you have fuel in and nothing out its the inj. pump..
If you had to choke it down to get it to s/off.. then either the sol. was messed up or the rack is stuck/sticking.. there may be an inspection plate below the inj. pump.. remove it and see if you can move the fuel rack by hand freely.. but seeing you didn't provide the year model or engine type.. who knows.. or even a pic of the fuel system would have gone along way..
