We bought a used 2009 4010 Trans last year. It had about 170 hours on it and was in great shape. My wife and kids use it on our place and to drive back and forth to her Mom's. I use it to haul stuff to the garden, haul the trash can out to the road and check the mail. It has been a great UTV!!!
We just had our first problem. The Mule is now having trouble idling and it will sometimes quit running. It surges at idle and seems to be running rough. I can't figure out what it is. A new fuel pump is very expensive ~$500. Injectors are $100 each as well.
I checked the gas tank vent lines (OK). I checked the air filters and intakes (OK). I replaced both spark plugs and checked that they were getting fire (OK). It sounds like the engine is either smothered (no air) or starved of fuel. I can't find any type of valve to check fuel pressure and I don't want to just starting replacing parts.
Can anyone give me some advice on how to diagnose fuel issues? Any similar experiences? I never realized how much we use the Mule until it has been down for a few days. My wife is about to drive me nuts to fix it.
I thought about detaching the fuel line as it exits the tank and where it enters the fuel rail. I could then blow it out with an air compressor. I couldn't find an in-line fuel filter, so I assume that it is in the tank. I would certainly appreciate any thoughts before I break down and haul it to a repair shop.
Thanks in advance for any advice.
