JD 5310 would not start

[wjkrostek]

no fuel thru the pump. I took the primer pump off changed the filter and bled the line. Then I thought of the fuel shut-off solenoid. I should of checked that first. It was dead and the fuse F2 was blown. I fried the next fuse just putting it at the holes. So know I know I have a short. l looked at the wire Diagrams. wire dia. only shows 1 wire to the shut off valve and I have three wires and two posts one hot and the other ground on my shut off. I figured the yellow wire was the shorted one so I left it unhooked and the tractor runs fine. But that yellow wire went some where and that's the question. What was the yellow wire going? Everything seems to work so far but something is not getting powered. Hopefully some one out there has this problem solved or has a better wiring diagram. Thanks for your time.

My guess is temp switch that is utilized in altering inj pump timing for extreme cold engine starts has failed. Disconnect switch(RE503242) in photo,replace fuse & attempt to start engine. If engine starts you have located the problem.

Thats a good guess..
Just unplug it, replace the fuse..
IDK IF JD HAS COME UP W/ A FIX FOR THAT OR NOT.. BUT ITS VERY COMMON..
IF u live in a cold climate, I suggest u replace it.. IF NOT, dont worry about it, just leave it unplugged..

I haven't done anything as we are getting covered in snow here . As I was blowing snow I saw the temperature gauge works and the tractor starts and runs fine. There doesn't seem to need any help in cold weather for her to start. There must be more that one sending unit. Do you know? The books I look at don't show me where the parts are and I can only find one coolant sending unit. Thanks for your time I would of never figured this out with out your help for now I will run it unplugged. by the way tell me where to go so I can learn how to post pictures. I'm not good a computer stuff and I can't find how to post picks
