Customer Question

I have a Kohler diesel in 2015 1000 model Polaris ranger. When I turn the key off the engine keeps running for a couple of minutes like its shutting the fuel off but not the actual engine. Any idea of what is suppose to shut the engine down?

Page 55 in the service manual shows the Non=return valve, which is what should kill the engine on shutoff.

is that part of the fuel pump?
Customer: replied 1 month ago.
I am guessing it is not working. The only electronics I could find that would shut the fuel down was a wore to the fuel pump. But it would seem this would b a slow shut down if in fact this where I find the shut off return
Expert:  Curtis B. replied 1 month ago.

No, part of the injection system.

Should i find a wire to that valve externally?
Expert:  Curtis B. replied 1 month ago.

I really don't know, was looking at service manual my self. Looks to be a vacuum operated link to kill engine.

I see question is still open, did you find problem?

I have not found the problem yet. I am trying to figure out still where the line is to kill the engine. Polaris says it is part of the pump. I ordered the part and hopefully will know more by mid week. We tried clamping off fuel hose and "no quick shut down". If I knew what exactly shut it down or which wires it would solve my issue I think.

OK< thanks, A wiring schematic looks to be what is needed. I suppose Polaris won't send you one?

Customer: replied 1 month ago.
Naw. I cannot find one online for the diesel either. Polaris just says bring it to them and they are four days behind. Maybe if the part comes in today we can get them to give us something.

Thanks for your help. If you have access to a schematic or know where I could get one that would be great.
Expert:  Curtis B. replied 1 month ago.

No, all I could find was the Koher service manual, and it was vague!

Customer: replied 1 month ago.
OK if I can leave open the rest of this week that would be great.
Expert:  Curtis B. replied 1 month ago.

Sure, as long as need be.
