Was doing some backhoe work on my John Deere 4200 and when I got off to move the tractor forward I believe the tractor seat was not all the way down making the safety switch and the tractor stalled out. Now it will not start up again. I metered the seat switch and it was good, tried bleeding the fuel lines and the lines where they go into the injectors but still no luck. Can someone give me some ideas as to what I might look for or do to try and get it running again???? Thanks
John Deere 4200 won`t start, please help!!!

Does it crank? Something get stuck under the seat preventing the seat from making the switch? Fuses? Other safety interlocks (PTO etc.)?
Hope you get it going /forums/images/graemlins/smile.gif

Are your shift levers in neutral and clutch fully depressed?--Ken Sweet
Have a close listen behind the dash for a prety good " CLICK" maybe your fuel cylanoid isn't opening. Kinda hard to discribe the sound but it is a little louder and harder sounding than a electric points opening or closeing typ of sound /forums/images/graemlins/crazy.gif Mine has not opened "STUCK" before I just turned the key from off to the next position "ACC." a couple of times and it opened and started like it should. Hope it helps ya.

A bad What? thermistor
PROBLEM:
the fuel pullin circuit does not engage On examination of the solenoid the is evidence of oil within the solenoid which requires additional force to pull in the plunger Replecemnet solenoid reacts the same
SOLUTION:
Consider the fitment of a replacement Thermistor part no LVU10323 The thermistor controls the operation of the fuel shut off pull in relay Should the relay fail to engage the Thermistor may not allow an earth circuit for the relay thermistor may be disengaging prematurly to expell the oil behindn 6the plunger Addition lnfo: for cold conditions use a 5W 30 engine oil the lower viscosity oil will be displaced easier from within the solenoid to allow operation

Hello.........Thanks to all that replyed. The thermister solved the problem. Went away for a few days and came home and saw the reply`s about the thermisters going bad so I called the dealer up and he had 1 in stock. Put it in and she fired right up!!!! All that frustration and down time or a $3.79 part!!You guys are all really great, and this forum is super!!!! Thanks again so much for everyone`s help!!!!

That's great, I want to thank the guys here at TBN and I didn't even have a problem. I can even say how cool it is to see you guys helping us newbies out, I just wish more people could act the same way, we would have a much better world. Thank you.
I found out the hard way on my JD 4400,luckily it was under warranty,JD replaced the fuel pump/starter and the problem was never corrected and they came to my house one day while I was out working on the tractor and the JD tech had the thermistor in hand,he installed it on the spot and I never had the problem again.
