You should be able to replace the fuel pump through the trunk. Beneath the carpet in the trunk should be an access panel. Once you remove that panel, all the electrical connections and fuel lines can be disconnected. Remember to disconnect the negative battery cable prior to service, and to take necessary precautions in regards to fuel spillage that may occur. I hope this helps.

first disconnect the battery then check how the serpentine belt is lined up so u can take it off and put back on. Then the pump should be on the side of the motor with 9or12 bolts there could be more! after taking out take razorblad and skrap the old gasket clean wipe of then put new gasket and pump back on dont over tighten the screws cuase the pump my be aluminum.

Yes, it is usually 25 amp (Yellow). There is also, a relay for the pump. Most of the fuses are under the dash...you can check your owners manual to see exactly where the fuse panel is located. The relays are under the hood. If the relay is working properly, you will feel a clicking motion while letting someone else turn the ignition on, but don't attempt to turn it to start the engine since this will cover the noise that you are listening for. If you need to know which relay is for the fuel pump, you can ask at the Auto store. They should be able to help. If the relay isn't clicking, you can tap it lightly with a screwdriver handle to get it to work; however, if the pump isn't running and is original; it is most likely bad and some test needs to be done to confirm that before taking the pump out.
