question Zetor 5245 fuel problem

[Markk]

Park the tractor two days ago will not start. Will run with a little bit with either change fuel filter blew out line from tank to the
priming pump can’t seem to get a priming in it. Any ideas? Thank you.

Is the diesel tank clean?
Blowing through the line only helps if the dirt has been removed from the tank.

Are the lines from the tank to the feed pump really tight? Be careful, as the suction line is under pressure, leaks are usually not immediately visible because no diesel comes out, but air gets in.

Can you pump diesel with the hand pump?
If not - please check the valve in the fuel feed pump behind the large slotted screw. Remove, clean, reinstall.

If the feed piston in the fuel feed pump moves easily and has no grooves/scores, the filters are not clogged, the injection pump is not defective (regulator is stuck) then it should work.
