 620i XUV 4x4 whining / buzzing noise .......

Picked up a used 2008 John Deere Gator 620i XUV 4x4...............

There is a high pitched whining / buzzing noise constantly when the engine is running. Almost sounds like a weak seatbelt warning alarm.......

Anybody have a clue on a cause or solution?

THANKS! ~Z~

I have the same problem. Changed the fuel filter, then the fuel pre=filter just before the fuel pump and the fuel pump and the whine and poor performance (stalling and lack of power) remain. Disconnected the fuel line at the engine and the amount of fuel pumped thru is minimal at best. Tested the original pump and the output was normal for a good pump. Followed the fuel line to the tank and inspected the inlet screen, that was clear and the entire fuel line was clear.
Question: Does the on board electronic limit the voltage to the pump?
