kubota diesel not firing

im looking at a jacobsen with kubota diesel that wont fire the compression seems ok but not for sure the injector lines have been takein loose and they work as they should was told that ran then sat and notrun for 6 months or so and now not firing took the mechanical fuel pump off and tried an electonic and its not the pump it works also would like to know what wrong thanks

The small Kubota Diesel engines are the Most reliable engine you will ever see...
They can set for YEARS and fire up without a problem... Diesel fuel Old or New will be good fuel...
I am not sure what you are referring to by "not for sure the injector lines have been takein loose and they work as they should"

What engine is it, and what controls the fuel shut off lever on the rack?

Is there a manual that comes with this unit?

Common problems:
Contaminated fuel
Air in low and/or high pressure fuel pump
Glow plugs not functioning properly, if so equipped
Low battery
Fuel shut-off solenoid not working properly
