JD 2305 starts, but won't keep running.

Ok I pulled the fuel selenoid out and turned the key on. According to the dealer service dept. the pin that sticks out should move in when the key is turned on. No movement there, so I tried starting the tractor with the selenoid out and the tractor started right up and kept running, yeah. Now I read something about a V4 diode or some other part that is probably the problem and not the selenoid. I haven't been able to locate this part any suggestions?

Thank you for the post. I have to work the next two days but am off Thurs. if the weather is good I will find that diode and check it before I buy a new selenoid. I couldn't find it, but I believe I will be able to now with the photo that the guy posted. Thank You so much! I will post my end results in a couple of days..

You may also want to look at this post. Thread 5 of this post has a wiring diagram and thread 8 has a page from a manual on how things work. While the V4 diode maybe bad it also speaks to why the diode maybe losing power due to a safety switch issue.

Well I tested the diode and it is ok. The test on the selenoid wasn't. Repair man at the dealer said to turn the key and with the selenoid plugged in, the pin should pull in. Sometimes it pulls in and sometimes it doesn't, but after about one second it comes back out. I started the tractor and it runs fine without the selenoid in. Only issue I might have is there was oil inside the selenoid. The repair man told me that there is a seal in the injector pump that keeps the oil out and that could be bad. The good news is I found a new selenoid on ebay for $38.00 instead of $180.00 that the dealer wanted. Hopefully this will end my problem. Thank you to everyone for the help. You saved me a lot of money and it is greatly appreciated.

Well Ijust put the new selenoid in, but tractor still does the same thing so back to square one I guess. Tractor runs fine without the selenoid in, not sure what to even check now.

I would say you have narrowed it down to being an electrical problem. In that you do not have enough voltage for the hold in for the fuel shutoff solenoid. In the first post referenced this person said -- looked through the schematics again and found that V7 Diode appeared to be the same one and it just powered the Hazard Flasher. I located V7 two up from the V4 and verified its wire colors (Red, Red, Green/White), removed it an put it into the V4 socket and everything worked fine (except the hazard lights)! --

I know you said you tested the diode, but I suggest you swap the V7 and V4 diode. I know a diode is easy to test, but it cannot hurt to try this.

Looking the wiring diagram in the second post if it was a safety switch problem, most likely it would not have started.

sound very much like ignition switch or fuel shot off solenoid? gets fuel when cracking but as soon as you let off the key shot off closes and it cuts fuel? test light on fuel shot off might do you some good.

sorry I did not read the links on JD 5210's post before I posted I believe he put you headed the right way. let us know what the problem was once you get it fixed...might help the next guy, what ever you do don't start just changing parts hunting for a problem, most times this cost more than sending to the dealer.
