Kubota BX2200
Tractor has been starting great all winter in sub freezing temps. Pulled it outside to thaw snow from bucket for the day. Started and put tractor to bed. Next day tractor cranks but will not start. Checked glow plugs good. Next thought water in fuel. Put a little treatment in tank and changed out both fuel filters. Cleaned/blew out fuel lines and injector lines. Opened bleeder screw on injection pump have good fuel flow. Inline fuel pump is good. Still no start. Remove fuel stop solenoid to check operation pulls in when cranking like it should. Still no start. Air filter is clean as well. Thoughts??? Have no more hair to lose.

Check the ignition switch. I just had to replace mine. Mine was failing to keep the solenoid energized. I'd hear the fuel pump and solenoid, it would crank, maybe run a second and die. Other symptom was that fuel gauge wasn't reading.

Has to be one of three systems: fuel, air, and heat (glow plug/compression) if the starter turns it over. Check one system at a time. My BX, in 1500 Hrs has never failed to start, except when fuel filter was plugged. You already eliminated that. Jumper around the switch and verify the solenoid/switch. There are several electrical interlocks in that system. The WSM has bailed me out many times with wiring side problems. There is probably a relay in there some place also. You can go crazy tracing electrical circuits w/o the wiring diagram.
