The fuel pump should not run continually when the motor is not running. I am assuming you mean when you first turn the key on, not when the motor is running as you would not hear it at all over the engine noise. (and would not run)
When you turn the key on, the fuel pump should still have retained enough pressure to only require a quick blip or two from the pump. You may just not hear it possibly.
But if it is not functioning correctly, read on.
First, the fuel pump is non-serviceable. It also includes the fuel sender and pressure regulator.
It gets better.
The fuel pump is an integral part of the fuel tank meaning you must replace the entire tank to replace a faulty fuel pump.
You can perform a fuel pressure test if it powers up, if not perform a continuity test. There is also a voltage test to check. If all the tests check out ok, but there is still a problem, take your machine to an authorized Polaris dealership for ECU testing.

CHECK FOR POWER AT FUEL PUMP CONNECTOR AT FUEL TANK

The fuel pump should run for a second or two when you first turn the key on, but then shuts down to prevent the engine from flooding if the computer does not get a signal from the crank or cam sensors which the computer uses to trigger the ignition system. So no spark no fuel. Check to see if you have a spark in the ignition system.

Might check the coolant sensor. Make sure it is reading correctly. If it is still reading cold on your coolant sensor it will tell the computer to run as if it were cold telling the computer to send more fuel when in fact it doesnt need any because the engine is already warmed up.
SOURCE: Camry just quit running. I can't hear fuel pump,
The engines oil pressure switch has a third wire which is connected to the fuel pump. The oil pressure gauge may work although the third wire to the pump may be at fault causing your delimma
Once the engines oil pressure reached the normal operating range the computer shuts down the oil switches third wire to the pump and the relay takes over until you shut the emgine off

I CHANGE CAM AND CRANK SENSOR,FUEL PUMP,COMPUTER BRAIN BOX AND COIL PACK STILL GETTING NO FIRE UNLESS I JUMP A FIRE WIRE FROM BATTERY
