John Deere 4400 Tractor won't start

[Klabautermann]

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?

 

[Klabautermann]

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?

 

[Tx Jim]

check for blown fuse or loose wire.

Here is the web-site to parts catalog/picture TXJim provided.

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

 

[Klabautermann]

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!

 

[Klabautermann]

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.

 

[Klabautermann]

Can I test this thermistor?
Remove and replace is not so easy, since I am in Walnut Creek. The dealer is miles(!) away in Stockton!
I sent an e-mail to Godfrey Daniels. He had the same problem. Maybe he can tell me how to diagnose this...
If I could rule out the solenoid, by testing it, I would concentrate on this mysterious thermistor.

You may want to look at this post and thread #12 as to what the ohm readings should be. Also looks like there is some other good info in that post.

The fuel solenoid may not be energizing to allow fuel to flow to the injector pump. Also check and see if fuel is being delivered to the injector pump. Could be the lift pump has gone out.

 

[Klabautermann]

Which two of the three solenoid wires would I touch to a battery, to test it?

Another (hope it isn't a duplicate) thread on the thermistor that may offer some help.
