Hello,
I have a Kubota MX500Su. It stop working few months ago and I been trying to started but it does not work. The tractor crank but does not Start . I been checking all the fuel system but no luck yet. I change the fuel solenoid, the fuel PUMP, fuel filter and bled the system. Since the fuel line on top of the block where the injector are can not be easily serviceable I disconnect the fuel lines on top of the fuel pump block ( for testing purpose and bleeding), but there is not fuel coming at all. Battery is also new
What else can I check?
THANKS. :)

I wonder if you might have gotten a bad fuel solenoid? We do not have a lot of issues with those pumps. ....

Art,
I did changed and tested the fuel solenoid. :(
There is fuel coming from part " No 120" on the drawing (before entering that engine block) but not fuel coming on the top where the fuel lines are connected to take fuel to the injectors.
There is a mechanical part on that block that can get clogged?? ....
