John Deere JD 5303 Problems

Tractor John Deere JD 5303 won’t start. It worked early in the day, then later it cranks more, but no
start.

I assumed there was water in the fuel so I emptied the fuel filter. Then I reinstalled the filter
and used the hand pump over the filter to push the fuel through the lines. Does not start.

I sprayed some on the intake and it lit up once, so it confirmed to me that it was
fuel shortage problem.

I can get the fuel to leak at the inlet fitting to the injector pump, and at two of the
bottom fittings, but no leaks on any of the three lines to the cylinders. Watch
Attached photo.

injector. The fuse didn’t blow, but it still won’t start.

What other possibilities could there be?

In your photo, it isdirectly behind the injection pump towards the front of the engine. Solenoid is insideinjection pump. If you connect 12 volts to the terminal under the rubber cover, you should hear a click.a click should be heard. It’s not very loud, but you can hear it.
