The fuel pump is in the fuel tank. You have to remove the fuel tank to get to it. The fuel pump is a complete assembly including the fuel sending unit. Aprox $250.00 some you can get the pump only and replace the pump on the sending unit aprox $120.00. the unit is held inplace with 6 small boltd. make sure you clean top of tank off befor removing assembly. so dirt does not go into tank. replace seal also.

SOURCE: 1997 Ford F150 Electric Fuel Pump will npt pump

Did you check the fuel inertia switch in the passenger side kick panel ?

The fuel pump is powered :
the fuse to the fuel pump relay.
The fuel pump relay to the fuel inertia switch
The fuel inertia switch to the fuel pump itself.

At the fuel inertia switch in the kick panel, power from the relay is the Dark Green w/ Yellow stripe wire and the pink w/ black stripe wire is the power. from the fuel inertia switch to the fuel pump.

If you jumper the fuel pump relay, you should hear it run. If not pull the fuel pump relay, and check the pins in the relay socket, pin 30 should be the power from the fuse.


If you have power at pin #30, jumper the relay socket as shown with the red line above, and check the dark green w/ yellow stripe wire at the fuel inertia switch for power.
Press the button on the top of the fuel inertia switch, and check for power leaving the fuel inertia switch on the pink w/ black stripe wire.

This is tests good, check for power at the fuel pump, same pink w/ black stripe wire.
Fuel inertia switch info is in the owners manual, If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

Replacing a fuel pump

Relieve the fuel system pressure and disconnect the negative battery cable with a socket wrench. Remove the spare tire cover (if present) and trunk floor so that you can open the access panel and disconnect the electrical connection from the fuel pump.
  • Remove the fuel pump's electrical connector and disconnect the quick connect fitting from the fuel pump. Remove the fuel tank locknut using tool 07AAA-S0XA100 or the fuel tank retaining bolts with a socket wrench, depending on the year and engine. Remove the fuel tank.
  • Install the new fuel pump using the items included in the kit and be sure to replace the gasket and O-rings. Align the arrows on the fuel tank and pump.
  • Complete the installation by reversing the removal procedure.

    CAUTION The fuel injection system remains under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.
    1. Relieve the fuel system pressure using the recommended procedure.
    2. Disconnect the negative battery cable.
    3. Drain the fuel tank, then remove the fuel tank from the vehicle.
    4. While holding the modular fuel sender assembly down, remove the snap-ring from the designated slots located on the retainer.

    WARNING The modular fuel sender assembly may spring up from its position. When removing the modular fuel sender from the tank, be aware that the reservoir bucket is full of fuel. It must be tipped slightly during removal to avoid damage to the float.
    1. Remove the external fuel strainer.
    2. Detach the Connector Position Assurance (CPA) piece from the electrical connector and detach the fuel pump electrical connector.
    3. Gently release the tabs on the sides of the fuel sender at the cover assembly. Begin by squeezing the sides of the reservoir and releasing the tab opposite the fuel level sensor. Move clockwise to release the second and third tabs in the same manner.
    4. Lift the cover assembly out far enough to detach the fuel pump electrical connection.
    5. Rotate the fuel pump baffle counterclockwise and remove the baffle and pump assembly from the retainer.
    6. Slide the fuel pump outlet out of slot, then remove the fuel pump outlet seal.
    To install:
    1. Install the fuel pump outlet seal, then slide the fuel pump outlet in the slots of reservoir cover.
    2. Install the fuel pump and baffle assembly onto the reservoir retainer and rotate clockwise until seated.
    3. Install the lower retainer assembly partially into the reservoir. Line up all 3 sleeve tabs. Press the retainer onto the reservoir making sure all 3 tabs are firmly seated.
    Gently pull on the fuel pump reservoir from retainer to assure a secure fastening. If not secure, replace the entire fuel sender.
    1. Attach the fuel pump connector.
    2. Fasten the CPA connector to the fuel sender cover.
    3. Install a new external fuel strainer.
    4. Install the modular fuel sender.
    5. Install the fuel tank in the vehicle.
    6. Connect the negative battery cable.
    7. Pressurize the fuel system and verify no leaks.

    How how do I know if my the fuel pump has gone bad on my 2004 s-10 pickup?

    spray quick start. If it starts you know you have a fuel issue. If it doesnt start you have an ignition issue. If you have no fuel pressure or ignition spark then most likely its a crank sensor issue. If you have a timing light that can show low RPM values then cranking you should have 100 to 200 rpm and the light should flicker. If no flicker then you have some sort of ignition issue.

    Hi. the fuel pressure sensor is part of the fuel pump assembly. You will have to remove the fuel pump to replace this. I would go ahead and replace the fuel pump while you are there.You will have to Pull the strainer off the fuel pump and discard it. remove the retaining clip for the fuel pressure regulator so that you can remove the fuel pressure regulator. Disconnect the electrical connections for the fuel pumps and the fuel level sensor. Remove the retaining clip for the fuel level sensor and remove the fuel level sensor by squeezing the locking tangs. the sensor is incorporated in this area.

    Please rate and god bless.

    How do I replace the fuel pump on a 2006 chevy avea

    I assume you meant a Chevy Aveo.
    -Remove the rear seat.
    -Remove fuel pump access cover.
    -Disconnect electrical connector and fuel outlet line
    -Remove lock ring
    -Pull out fuel pump assembly from the tank.

    Reverse this to install but make sure you clean out the groove where the gasket sits. A lot of the time dirt/debris will get in the groove when you remove the pump and can cause some leakage later on.
