2010 RTV 900 Loss of power and stalled

[kubota.ray76]

Good morning everyone, yesterday I was out at my property checking on my beehives.

After I wrapped things up I jumped in my RTV started it up drove maybe 5 feet then it started to idle down and died. I started it up again and it fired up but died down again?

The fuel was at half a tank and the fluids and filters were good. I was eventually able to get the vehicle started by removing the air filter and using starter fluid while cranking the engine.

I have a suspicion that air might be leaking into the fuel lines? But I’m not that mechanical inclined.

Any suggestions or ideas where to start when troubleshooting or how to find theair leak?

Any recommendations or suggestions would be greatly appreciated.

Ray

Most likely problem is that you have gunk in your tank that has blocked the outlet.

Other strong possibilities:

• Your fuel filter is plugged.
• Your fuel pump failed. I don't know if your particular beast has a lift pump or not, but a lift pump is usually pretty inexpensive compared to an injection pump, and far more likely to fail.
• Water in the fuel.

Air in the lines is a possibility, but it's way down on the list.

Good thing if you do have a lift pump - it's usually pretty easy to test one. Just disconnect the output line (at the injection pump, if you can. Kills two birds that way.) Now turn on the key and see what kind of output you get. If you get none, or only a very little, you know the problem is somewhere between the lift pump and the tank. Now disconnect after the filter, but before the lift pump. If you get flow by gravity, your lift pump is shot. If you don't, you know the problem is between the lift pump and the tank. Just work your way back, looking for fuel.

Also, please post the exact model and year. It often makes a difference in diagnosis.

The RTV900 has a mechanical lift pump so the engine needs to be turning for it to pump fuel. I have seen them fail though it isn't common.

Thanks, I’ll give a try later on today
