kubota B21

Clarkschapel · Oct 13, 2015

Need help Please, I have a B21 kubota Diesel tractor and when I start turning the engine over it fires up and then stops running like its out of fuel. changed the fuel filter out did not help, could it be because i have a tube on my fuel injection pump that is leaking, tried to find part number for that and have not been able to do so. Any suggestions would be helpful thanks Clark.

Check the fuse for the shut-off solenoid. The solenoid is energized with the "start" position and then held open with the "run" position. If the fuse fails the engine will start with available fuel then quickly dye since no more fuel is being supplied.

If the fuse is good then test the solenoid

Daves1708 I checked the fuses pulled them out tested each one with ohm meter and didn't get a reading on some of them cleaned the terminals and replaced the fuses back into the fuse box and it fixed the problem. it was a red 10 amp fuse. thanks again
