John Deere 4400 Tractor won't start

Klabautermann · Sep 17, 2014

It cranks fine and runs on ether (Ugh! It sounds bad!)! I checked the fuel filter(clean!). I turned the fuel shutoff valve on-and-off and there is only a dribble for both positions. Is there a solenoid valve somewhere?

Is fuel control solenoid(parts key 8) clicking when ign switch is turned to on?

No click. Tractor sat idle for a couple of months... What should my next action be?
Where did you find the parts picture? On line somewhere?

check for blown fuse or loose wire.

thermistor.....little chip can give you a fit and only cost like $8.00.

No blown fuses (except the tail light) and no loose wires....
There is a 3-wire connector and red/white/black wires leading to the solenoid...
Thank You much for the John Deere Parts Catalog!

Can I unplug this solenoid and test it with my multimeter?
Or... connect two of the 3 wires to a battery and listen for a "click"?
Which 2 wires? I would not want to burn it out, by jumpering the wrong ones...

I accidentally entered the same message twice and deleted this one

type thermistor into the search engine....many posts about it. There is even a picture from last weeks post of what it is. It is required for the fuel solenoid to open. Thus the either burned but tractor didn't start. I have a 4400 and had same issue.......replaced thermistor and tractor starts right up. You find it buried in wiring harness behind the fuses below the steering wheel.
