I have a 272d gsl00394 that died as we were moving dirt. It will start for just a split second then immediately engine will die. It has the display screen to pull codes, so this is what I found (with the book icon on screen).
E-876-3, e232-1, 01-87, 01-0, 3915-3, 2685-8, and 96-3. It is stuck in the pasture 90 miles from a cat dealer and we can't even pull it on trailer to take it in (wheels locked). Any help would be very appreciated!

The first and easiest thing I would suspect is the electric fuel pump. If you are looking at the engine it will be located on the left hand tower. When you turn the key on you should be able to hear it run for a few seconds, then cut off. It is pretty noisy. If you don't hear it then that is likely the problem.

As for the codes, Here is what I could find.
The E-876-3: High system Voltage
96-3: Fuel Level Sensor, Voltage above normal
2685-8: Left Drive Motor Speed Sensor #1, Abnormal Signal
3915-3: Lift Linkage Limit Switch, Voltage above normal

There are other members on here who will be of more help. I am sure they will chime in soon.

The fuel pump is coming on when the key is turned on for 5-10 seconds. We did replace the fuel filter and it filled properly. I suspect the fuel pump may not be reenergizing when the key is released (from start), so I will see if I can wire it to make it run continuously for now (just to verify it isn't the issue). Doesn't seem the codes would have anything to do with engine running tho.

I will check grounds also to see what I can find. I don’t know how long those codes have been in the machine, never knew I could even look at them until I found instructions here. It is possible they have been there awhile. Is there a way to unlock the wheels to be able to load it on a trailer? It is currently 20 miles from my house in pasture with no cell service. Thanks for the suggestions, I am definitely going to try them.

Have you taken the fuel line coming out of the transfer pump loose and turned the key on to verify that you are getting good flow there? There is a small filter on the inlet to the electric fuel pump that could be stopped up. In that case the pump would run, but would not be able to move very much fuel. Just a thought.

Have you visually verified that there is fuel in the tank? I'm not saying that to be a jerk, I have overlooked that plenty of times. With the "Fuel level sensor: voltage above normal" code, it could be that the gauge is not reading correctly and it is just out of fuel.

As for pulling it onto a trailer, there really isn't an easy way to do it if the machine will not run. Your only real option to get the thing to roll is to remove the chain box covers and take the sprockets off of the drive motors. If you do decide to do that BE VERY CAREFUL. when you pull the sprockets off the motors there will be nothing to keep the machine from rolling.

G..G..G..Granville.........!! Fetch your cloth.
Does anyone have a drawing of the fuel pump wiring? Relays etc for this machine?
Here's the Electrical Schematic for the complete machine.

Regarding moving the machine if you have access to a tilt tray recovery truck equipped with a winch there is always the possibility of putting steel plates under the tyres and simply dragging it on to the truck.

Thank you very much for the electrical schematic!! That should help a lot. I haven’t checked the flow of the pump yet, but it is on my list to do now. And no offense about the fuel level, I have made that mistake several times also. My dad was running the machine when it died and he said he put 5 gallons in to make sure it had enough, but may add another 5 for good measure. I was thinking metal skids or even cutting some plastic barrels and putting under the tires so it slides easy and wenching it on a trailer. It is getting loaded today running or not. Thanks again for all the suggestions and help!

Well, I appreciate the help and was able to get the machine running again. I did check fuel flow, pump was running ok and there wasn’t an issue with the fuel at all. Should have checked the basics first. I did not know that my dad had just cleaned or replaced the air filters on the machine and was able to get the smaller inside one installed backwards. I guess when he put the machine to work, it sucked the end of the air filter inside the duct and blocked it. We only found this since I had idle turned up and started it a few times. He saw the intake air pipe collapse then pop back out as soon as machine died. I am thinking it did not have a air restriction code since it happened pretty much instantly. We removed the air filter and put it in correctly and machine runs great now. Machine would turn over and start but only run for maybe a second. Thanks to all again for the help!!

Stranger things have happened..
I take for granted that NOT EVERYONE takes the air box off when diagnosing.. Sorry, I missed that step..
THATS THE 1ST THING I do.. Pull the filters..
