Tractor won't stay running?

LS XR4040 Shuttle Shift

Turn the key motor turns over and and runs until the key is let back from the start position immediately dies. With the key held in the start position motor revs up. Going to go start trouble shooting but would love some suggestions.

On many of the larger tractors the fuel solenoid has two windings a start winding and a run winding,
they also may have two relays a start and a run relay.

I had the same problem on my tractor. My fuel shutoff solenoid has 2 coils, "pull" and "hold". It takes 30A to pull the solenoid open, but only 1A to hold it open. On mine, the "pull" coil runs off the starter circuit with a 1sec timer built in to shut off that coil so it doesn't burn up. The "hold" coil on mine runs off a different circuit and holds the solenoid open until the key is turned off. The issue with mine was that the wire for the hold coil has rubbed through and shorted to the frame, which popped that fuse. So my tractor would start and run fine for 1 second, until the pull coil released. Since the hold coil wasn't energized (blown fuse), the tractor would then shut back off. It took me a while to track the problem down to the wire. I thought it was the solenoid at first. Not so. Check your fuses. If one is blown, replace it and see if it fixes the issue. If it blows again, either you have a shorted wire somewhere, or the solenoid is shorted internally.

Pre fuel filter filled with sludge. Going to replace it and the fuel filter tomorrow. Hope that is it.

& just exactly HOW does a dirty fuel filter affect the electrical starting circuit.??
The answer is in post # 2 & 3..

Because I'm not a mechanic and the fuel shut off solenoid online is about $1500. No blown fuses. No loose or broken wires that I can find yet. I changed the relay out for a know working one and it didn't fix the problem. Really hoping it isn't the solenoid itself. Will get back to working on it next week. Thanks for all the input everyone.

That is one high priced solenoid,
can you see the actuating end of yours?
Or is it bolted right to the injection pump?
Some pictures might help.
Some times they can be mechanically held open.
I have seen a bungee cord used to hold one in the run position and if was physically pushed to shut down.

Have you checked for voltage getting to the solenoid with the key in the run position?

 

[snymat68]

You should also be able to check the resistance (in ohms) of the coil in the solenoid.
Ω = 0 = dead short internally = bad solenoid
Ω = 1 = wide open internally = bad solenoid
0 < Ω < 1 = should be in this range (specific value depends on solenoid)

take that in to your local NAPA or O'Reilly Auto Parts and see if they can cross reference it. Maybe even check a new holland dealer and see if they have it less, since odds are high there's a very similar New Holland model tractor....

Can u post a pic of the solenoid.??
MOST of them have the part # ON the solenoid.. that way u can search it by the actual P# & not by the tractor mdl.
Good luck.

Brought it to the dealer. Computer is junk. Grrrrr...

I'm having this issue now with an LS J2020H tractor. Cranks up but dies out as soon as I let the key loose. How did you solve the problem?

I hope you got it fixed by now, but sounds like the fuel shut off solenoid. If you are still having the issue, PM me and I will try and assist you over the phone if you have a meter

My J2030h did the same thing. I replaced the instrument cluster and that fixed it. A year or so later its doing it again. Something is getting wet it seems and causing the issue on mine. I store it outside with a cover. Ill have days where it will do that in the morning and Ill wait and try again later after its sat in the sun. Sometimes it starts, other times I say no grass cutting today. Im not thrilled about putting another dash in it again.

I have a 2015 xr3037h model LS tractor that won’t start now but this past Saturday it started fine bushhog for 2 hours shut it down now will not even turn over any thoughts?

Check the ground. Sometimes they get loose or corroded.

I just joined as I am trying to resolve this same issue on an XR4040 for a member who just passed away last week.
Tractor was dead in the back yard for days but I got it running good again, but it just dies after about two seconds. Pull solenoid winding checks fine with an ohm meter. However, there is not a one amp fuse listed in the parts manual anywhere for his tractor, an XR4040 cab version with Hydrostatic transmission. It does list some 5 amp fuses and they are the smallest size I found listed in the parts manual.
The solenoid which screws into the end of the injector pump body has two sets of leads attached. One lead set is a pair which appears to open the solenoid and there is continuity there.
The second lead set consists of three wires and I have not been able to locate in the service manual any kind of test procedure for this set of wires or what it is inside that they attach to or their function. I read with interest the post which says there is an Start solenoid and a RUN Solenoid winding. However, I was not able to read any continuity through what may be the HOLD side of the solenoid regardless of which two wires within the three wire cluster I connected ohm meter to. Clearly, something is causing the fuel supply to the Injector pump to shut off. I need to insert the voltage meter and reverify whether voltage remains present to the PULL solenoid once key is returned to RUN position. In an earlier test I saw voltage still present going to the PULL side of solenoid but I only left the key in run position for about a second instead of for several seconds. I never found a single blown fuse nor did I find a single relay which did not close and pass current when energized from a separate external 12 volt power supply.
Any thoughts, suggestions, anyone? This tractor is about a two hour drive from where I live so next time I drive down to work on it, I hope to have a better idea of what I might be looking for, Owner was a best friend of over 25 years and passed shortly after his diagnosis of cancer before I could fully resolve tractor issue for him. I don't even know what user ID he used.
I actually worked briefly at an LS dealership but most of my limited tractor experience comes from repairing, rebuilding and maintaining personally owned farm tractors and machinery down through the years.
