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.
