My always reliable Mahindra 2015 (gear) 4WD suddenly stopped starting

[knute_m]

I haven't been on the forum for quite some time. Unfortunately, my 15 year old Mahindra 2015 won't start, and I need some assistance. It has just less than 1000 hours on the meter.

It was working just fine. My son and I were getting it ready for winter a little over a week ago. We were removing the backhoe, so we were starting and stopping the engine every few minutes as we were adjusting the backhoe and hydraulics. Just as we were ready to pull away from the backhoe, with all of the regular hydraulic lines re-connected, my son jumped on the tractor, which had been running about 1-2 minutes before, and had been in use for at least the previous hour or so. The engine turned over just fine. But it wouldn't fire. No smoke or even a hint of ignition.

I feel certain that the glow plugs are working. Because of the cranking we've done, I've connected my old 110 amp battery booster to keep from totally killing the battery. The glow plugs appear to be drawing about 25 amps when they come on.

It was probably 40 F degrees when this failure occured, so I wasn't too concerned about the fuel, which had anti-gel and cetane-boost added when we re-filled the tank earlier in the day. Just in case, we replaced the fuel filter, which probably only had 20-30 hours on it. I also half-filled the filter bowl with Diesel-911, just in case there might be some jell or ice somewhere between the filter, fuel pump, and injectors. We bled the air from the fuel filter input, filter out to the fuel pump, and at the injector air release.

That kind of leaves the fuel-stop solenoid as the culprit, unless there is something really seriously wrong. BUT, I CANT FIND THE FUEL SOLENOID! I've got a full non-Mahindra service manual that is really detailed that covers the Cub Cadet 7000 series and Mahindra 2000 series, but it has almost no information about the fuel solenoid, except for a Mitsubishi part number. Otherwise, it only shows up on the electrical wiring diagram, which doesn't help me locate it.

Does anybody know where the solenoid it is located? And, if the solenoid isn't my problem, does anybody have any additional ideas on what could be the problem.

I'd have my local dealer come look at it, but it is at my son's house. So, it is well over 100 miles to the closest dealer, making it a pretty costly service trip. I can't get the tractor on my trailer because I have a tooth bar on the FEL bucket that I always use as my primary emergency brake -- and the teeth are stuck well vertically into the ground. And, obviously without a running engine, the bucket isn't going to move. Plus, the weight of the backhoe is still on the tractor frame.

Thanks for any possible assistance.

Can’t tell you anything about the fuel solenoid location. But just verifying you didn’t trip an interlock- say move a PTO lever or seatbelt safety. The newer ones won’t crank at all. But that vintage I don’t know. I’d also verify all the fuses are good. Mahindra was/is good at hiding a few in the harness. Perfect to nothing seems less like a solenoid....but who knows

My 2615 has a lockout for only the PTO lever, and the shift lever. I never gave thought to a fuel solenoid on mine, and my owner's manual doesn't mention one. However, a quick search found one, and ouch, $$$. FUEL SYSTEM PARTS FOR 2615 MAHINDRA TRACTOR

I also found this information. Hope it helps you. These are such fine tractors. Just wish mine had more lift capacity like the Max series does. https://www.tractorforum.com/threads/help-mahindra-2615-starting-issues.32757/

The solenoid should sitt somewhere on the injection pump and is feed with 12V

Try to raise the loader/teeth while youæ±*e cranking the starter. Not sure if it値l work, but worth a try.


I had a fuel shut off solenoid go bad in my MF1540 a few years ago. Had the dealer come out and fix it - no way in the world I壇 have been able to locate it and then actually change it out since it was buried pretty good in the front of the engine

Good luck

On my 1526 [ Mitsubishi like yours ] three cyl, the fuel solenoid is located on the right side of the engine a little above the injector pump. Mine looks like a small metal canister with two wire going into it. The fuel comes from the tank and goes thru a clear plastic fuel bowl, then from there up to the shut off solenoid. Your solenoid might not be the problem. ANY [ ' ANY ' ] air or water in the fuel lines will cause this problem. In this picture, the solenoid is the silver thing in the center of the picture. These are indirect injection diesels, and NEED the preheaters to work when cold to fire. You should put a voltmeter on them to see if they cycle, and also check for resistance. Forgot ..... " MERRY CHRISTMAS to you and yours, stay safe ... !!!! "

This was my thought as well. Cranking will lift an empty bucket on the 7520. I was delaying reply hoping others could come forward with info on the fuel solenoid on the OP tractor. Good gamble, it seems :thumbsup:

Thats gotta be it -- and good chance it is stuck in the actuated position, not opening automatically when the electric shutoff signal expires. ... Warm it up and tap on it maybe. A hairdryer might be enuf.​

I have a 2216 and this thread got me curious as to where or if my 2216 had a solenoid. Searched the 2216 parts listing and none found and it appeared from the fuel pump to the injector pump nothing was in between, so I found a service manual for the 2216 Mitsubishi engine (S3L-W414RH) which has a fuel system schematic. The schematic does not seem to indicate a solenoid in the fuel system path. Don't know if the 2015 is similar to what I have, but possible. Fuel filter and pump are at rear of tractor on the 2216.
I just went through a filter change for a similar problem to the OP. I did the air bleeds at the fuel filter, but not the injector pump. The engine faltered and stalled on the first start try, but caught on the second. I would try another bleed at the injector pump an be sure the fuel is working OK (I can hear mine clicking while the glow plug light is on).
I also had to change the o-ring on my filter as the previous o-ring had some flats on it that wouldn't reseal when the new filter was installed and leaked around the bowl top (could have possibly sucked air also).

Thank you all. I finally found where the ETR solenoid is located. Actually, I was able to download the service manual for the Mitsubishi SL-Series Diesel engines, which includes the 3SL2, which is in my Mahindra 2015.

The solenoid is located directly above the oil filter, and just behind and below the where fuel injector lines attach to the engine.

The manual can be downloaded from Download Mitsubishi S3L Service Manual

The photo posted by JerryK is actually the fuel pump. On my tractor it is located under the seat area.

As for air or water in the fuel lines or injectors, these series of tractors are pretty well designed to correct for that problem. The fuel filter assembly has an intake and an output screw designed to be loosened to let air out of the fuel filter intake and from going to the fuel pump. Then there is another place where the fuel goes into the injectors designed to be loosened for air or water to escape when the key is turned to the run mode, turning on the fuel pump.

Anyway, thanks to all who responded.
