Tractor has a fuel primer pump. If you loosen fuel line from the primer, and pump the primer. does it pump fuel?

Expert:  Curtis B. replied 1 year ago.

If not, you have a clog before the primer, in the tank outlet, or water separator.

If you have fuel to the injection pump. and nothing out, Check the fuel shutoff solenoid in the injection pump. It has to have 12 volts as soon as key is opened.

Expert:  Curtis B. replied 1 year ago.

If it does not, you get no fuel to the injectors.

Customer: replied 1 year ago.
o.k. tell me where is the shutoff solenoid in the injector?
Expert:  Curtis B. replied 1 year ago.

It is one the side of the injection pump, near the end that that the high pressure lines to the injectors.

Does the solenoid click when key is turned on? It has to have 12 volts at all times the key is on. It has to open the fuel passage to the injectors.

Expert:  Curtis B. replied 1 year ago.

Of it does work, and no fuel to the injectors, your injection pump is bad

Customer: replied 1 year ago.
o.k. will do some more ckecking tomorrow and get back to you. thanks curtis

Remove the solenoid and see if you can remove the inner plunger. Reinstall less the plunger and see if engine starts.

Expert:  Curtis B. replied 1 year ago.

I assume the fuel is not squirting at the injectors,just dripping.

Customer: replied 1 year ago.
i did get the fuel to squit today, that part is fine,
Expert:  Curtis B. replied 1 year ago.

If fuel is squirting at the injectors, do you get smoke when cranking?

Expert:  Curtis B. replied 1 year ago.

What is fuel quality? No gas or water in the fuel?

Customer: replied 1 year ago.
no, all it does is turnover and not start

If you don;t have fuel squirting at the injectors , and the fuel shutoff solenoid is working, the injection pump is bad.
