You are looking for the constant control relay module- ( CCRM ) see below. The pump will be located inside the fuel tank.Most of the time , its the pump and not the relay but, it wouldn't hurt to check the relay out. Teh relay is housed in the CCRM. Its located behind the engine coolant reservoir.

I was just looking for another fuse and came across this diagram and it shows every fuse and relay and where it goes. The Fuel Pump Relay is in the O slot in the fuse box under the hood which is located near the battery. it is a 20 amp mini fuse. Hope this helps, i saved the link for future use if i need it, might be a good idea for you too. Good Luck here is the link.....
