I have a Kubota B4200 2 cylinder diesel that won't start. My first thought is that it doesnt fire up fuel so I suspect its an issue within the starter or fuel pump. I replaced the fuel filter and filled the bowl, it ran for a about 30ft then just died. No fuel at the injectors or even at the injection pump as I chekced. Hopefully its not the injector pump as I just got that rebuilt a year ago.
 
You might wanna go check the wiring to the solenoid for any loose connections or damage. You could also try to manually actuating the solenoid if possibe and if equipped to see if its stuck...

Check for air in the fuel lines. Might explain that. And yeah double check the fuel shutoff solenoid like @Ballantines1957 here said.
 
Hey,
Ive got trouble with auto-locking system. I have auto-lock set to 30s. but it seems its not working at all. Is there any condition that makes it unoperational?
