Try turning the kill switch off, key off, then turn the key back on, kill switch on and see if you hear the fuel pump then. If the system is already to pressure, I don't think the pump will come on. It's pressurizing the fuel rail when you first hear it.
I agree with Paul, lift the tank and check the connections on the bottom of the fuel tank for the pump, and the air box intake air temp plug on the right side of the air box to see that it's fully seated. Might as well double check that the vent and drain hoses are not crimped or tangled too.
If you've not had the tank up before, you need to pull the two vent/drain lines away from the bracket first.
