Help!!! John Deere 4200 will not start!!!!

[zdog]

John Deere 4200 4WD Hydro will not start, please help me out!!! I was doing some backhoe work and was on a slight incline, went to drive tractor forward and it stalled out. Checked fuel and it was low and with the incline could have ran out. (not sure) it didn`t sputter at all, just when I gave it gas to move forward it died suddenly. Filled it up and now I cannot get it to start. Towed it about 10 ft so that it is now sitting on level ground. I sprayed a real small amout of starting fluid in air intake and it ran for a couple seconds, I`m sure just on the starting fluid, seems like its not getting fuel. Drained fuel bowl, tried pumping the manual pump but still nothing, checked all fuses, can someone please help me out!!!

Don't use starting fluid if possible. The newer Yanmar's have a self bleeding fuel injection system. Not sure on 4200. Check if it has a plunger pump or bleed screw near the fuel filter.

Bleed the fuel system to the filters first and then bleed each injector at the injector. Start at the first one in line and work your way down the line. I bet It will fire right up. To move the fuel thru the system, You will need to use the starter motor, priming pump (on the fuel pump) If it has one, and starting fluid, if all else fails-- Ken Sweet

Get out your Owner's Manual -- I would think it has step-by-step instructions for the procedures of bleeding your fuel lines.

 

[zdog]

I have the owners manual and it says that fuel system is self priming. I will try and bleed at each injector like was mentioned above as soon as I find out how to do that?? any help on how to bleed the injectors??? Thanks again for all the help!!

A safer alternative to starting fluid is WD-40. Wet a rag or paper towel with WD-40, place it near the air intake. The fumes from the WD-40 will start the engine without the explosive burst you get from starting fluid. Local Ford dealer service tech gave me that tip about 20 years ago - works fine on diesel trucks too.

zdog,

On my 4700 there is a lever next to the fuel bowl cutoff fuel when changing the filter. If you have one see if its in the open position. Mine was tough to turn so it would be hard to believe that it moved.

Also check you battery and battery cables. Is it possible the BH usage could have move the battery connections around? Sounds like you are getting power though.

Is your fuel ok? Drain some fuel and see what it looks like. Put in fresh fuel and the Powerservice that disperses water. I forget if it was the white or gray bottle....

I could not start once it was because water was in the fuel. LONG story. But I had to change out the fuel filter, purge the fuel lines, put in fresh fuel, and Powerservice.

Later,
Dan

Every fall when the cold (30-45degF)damp weather hits I have trouble with my 4300 not starting . It has always been because of an open circuit in the thermyster for the fuel solenoid( 4yrs in a row).This 57cent unit allows full voltage to the solenoid to pull it in but drops the voltage after a few seconds so it has just enough voltage to hold it in. The little critter is somewhere behind the fuse panel and once the tractor starts and warms up evrything is OK until the next cold start. To do the initial start however I must remove the side panel to get at the three wires to the solenoid, then short the white wire to ground while hitting the key. It always starts instantly when I do this.
I have had the dealer change the thermyster then the problem goes away(even at 0degF) for the next year.Below 10degF I normally plug in the heater.

Another safer less harmful alternative to starting fluid is carburetor/choke cleaner, available at Wal-mart for about $1.50 a can. I drive a big diesel trucks and sometimes the fuel filters have to be swapped out without means of bleeding the system afterwards. It might take a half dozen attempts to keep it running with carb cleaner, but the air will eventually work its way out and the engine will run.

Thermistor...been there done that...easy $3.00 + fix

Have you got your 4200 to start yet? I have had mine crank but not start several times just while setting in the shop. Sometimes I would wait 15 min and it would start. I read all the posts about the thermistor and replaced it. Thought I had solved the problem, but had it happen again. I traced the problem to a loose fuse block in the fuse panel under the steering wheel. Pressing the fuses in to make sure they are tight solved my problem. Your problem sounds more electrical than fuel. I have found a lot of previous posts about 4200's quirky starting behavior and thermistor problems as noted by others. It would be a cheap fix to check the fuses and all other safety switches ie pto, seat, hydro pedals etc. Good luck

I believeit,s your safety switch under the seat thats causing you greif connect the wires together temporaraly with a small wire by pass the switch and see if that works

 

[Willl]

Don't think so. If it was the seat switch, it wouldn't even turn over.

I would think that since this thread was last active about 2 1/2 years ago that he has his tractor running by now.

The original post started in June of 2005, we need to help these guys out a little faster don't cha think?

I have your answer. I spent days on the same problem with my 4200.
Fuel cut of solenoid pn 119233-77932. On right side of engine by injector stuff. Remove bracket that is in way, remove 2 bolts, pull out sol. turn key to run. push in pin, bolt back on and start tractor. Order replacement part for $160 and it will work fine for another year and a half. I cut my bracket and only use one bolt so I can pull it in 30 sec.

Love it

I have had a similar problem with my 455 JD lawn tractor. The fuel injection solenoid gets gumed up after time, in my case 1700 hours. I took it apart, clean it up and coated it with a lite coat of olive oil. That was several years ago and I have not had any trouble with it since.

Next time the fuel solenoid on my 4300 goes I'm gonna make some kind of a manual system that I can control from the seat. I have a plate with a bolt on it that I've used while waiting for the dealer to get a new one but I need to use a wrench to shut off the tractor....

 

[Brimstone10x]

Seems like yanmar would have a manual fuel shut off that would fit on that style injection pump. I saw one that a guy had drilled a hole thru the bad solenod and ran a rod back so he could just push it in to shut off the engine.Not realy a good idea safety wise as the shut off is a major part of the safety system but sometimes you got to do what you got to do.
