fuel sending unit is in the tank. this is normal after about 75k miles and up. pump and sending unit are sold together. fuel sloshes from front to rear making the float on the sender rise and fall.

The Fuel Pump Relay is located in the Glove Box under a little cover on the upper left side. The Fuel Control Relay is the left relay and The Fuel Pump Relay is the right. To test these relays, swap them and then try to start the vehicle, or blow the horn. If the horn blows then use that relay for the pump and you may at least drive the vehicle where needed! If the vehicle starts, then replace them as a pair.

Go to the autozone website at autozone.com and register your vehicle. It's free and will give you access to an online repair manual for your vehicle. The procedures for changing the fuel pump should be available there. Sure hope this helped and best wishes.
