The fuel pump is located in the fuel tank, but your in luck!
If you remove the carpet from the trunk you should see an access pannel way in the back almost hear the back of the rear set. Remove the access pannel and you see the top of the fuel pump underneath.
Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
No, the problem is with the fuel level sending unit in the gas tank. This is normally a substantial repair task. Fortunately, your sender is sold separate from the fuel pump and both are accessible from the trunk under the spare tire. The labor should only be a couple of hours. Please let me know if you have any questions.
Relieve the fuel system pressure.
Drain the fuel tank.

Remove or disconnect the following:
When removing the fuel sender from the tank, the reservoir bucket is full of fuel. Use caution in containing the fuel.
Note the direction the strainer is pointing.

check in the trunk in the spare tire area for an access panel, or under the rear seat, usually 8 to 12 screws 2 wiring connectors and 2 or 3 hoses to disconnect. if you cannot find the access panel then the gas tank will need to be removed from the vehicle. good luck
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.
