I have a 2007 John Deere 2520 that I thought had a bad fuel shut off solenoid. It will start for about a second then shut off. I replaced the solenoid and still does the exact same thing. My next guess is the fuel shut off timer. How can I troubleshoot that? Just buying parts is getting expensive.
2520 will not start

Could be a safety switch. I'd jumper them out to narrow down the possiblities.

The safety switches, such as the neutral and PTO switches, will prevent the starter from cranking.
Bad fuel, water in fuel, bad fuel pump, clogged filter, those would be my first guess.

HI,
If it starts for a second and shuts off. Does it die just as you release the key from the start position to the run position? If so, I would suspect the ignition switch is not providing voltage in the run position. (Start position energizes both the run and start circuits) Check to see if you have voltage at the fuel shut off solenoid with the key in the run position.

In the on position with the engine off, can you hear the fuel pump ticking? If you can than the on circuit is energized. Beyond the fuel pump diesel don't really need much else since they don't have an ignition system.
Without knowing a little more that is what I would guess also.
Thank you for all the suggestions. It started and ran great last night still not knowing what is causing it. It might be a day or maybe a month but it will happen again. It will start with the key in the start position but stall with the it in the run position. I can hear the fuel pump running. Something is causing the fuel shut off solenoid to not retract in the run position. I wish I had a service manual but I can't find one. I don't know what to check next time.
Thanks again.
Thanks again.

Did you ever figure out the issue behind your problem. I'm trying to troubleshoot the exact same problems. Very frustrating. The tractor runs for 1.5 seconds and then shuts off. I don't have power to one side of the fule shuttoff solenoid. The other leg will power briefly for that 1.5 second and thats it.
No. I still don't know what was causing it. It's been running great lately. The tractor is a 2007 and that problem comes and goes. I took apart and reattached every wire connector I could find, then it started. No idea which one is the culprit. Good luck. Let me know if you solve the problem.

My early 2008 had a bad ignition switch.
Was acting up still in warrantee and had someone come out and change a fuse for $250.00. Of course it behaved for a couple months.
The second time I had someone come out when the ignition switch wouldn't even turn the dash lights on or anything else and it was a fuse again.
Couldn't convince anyone to try to figure out why it was blowing a fuse.
Just shoulder shrugs and a hand out for some cash.
In the meantime the dealer I bought the 2520 from lost their JD dealership and the next closer one went out of business. I went 40 miles away for a service manual and it took them 2 and 1/2 months to get.
I'm pretty much fed up with JD at this point.
Once I had the schematic in the manual I was able to prove the switch was bad and not anything else.
Really irks me that this switch started going bad under warrantee and I got no where trying to get it fixed. The switch isn't even expensive.
