SOURCE: replacing fuel filter 2000 impala

Disconect battery and releive the fuel pressure by opening gas cap and under hood with fuel pressure tester. then you need two open ended wrenches.. Go to driver side rear tire and just in front of the tire about a foot under the car you will see the fuel filter remove filter mounting bracket apply one wrench to filter nut and one to fuel line side and turn oposite directions, might want to spray with some penetrating oil fist to break loose, then remove plastic clip from other side of the fuel filter and it should come right out.

REMOVAL & INSTALLATION
(see Figures 1 and 2)

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.

INERTIA SWITCH for a 2003 Chevy Impala


Chevy doesn't have a inertia switch . If the engine dies after a wreck the fuel pump shuts off because the PCM doesn't see a crankshaft position sensor signal . The engine has to be running or cranking . GM Fuel Pump Relay Testing YouTube

Where is reset button for fuel pump on 2003 Chevy impala?


Inertia switches just don't go bad. The last ones I reset were back in the eighties because Ford crown vics would pop because of opening the trunk. In thirty+ years, I have never replaced one. If you just replaced the fuel pump, I would check for power and ground to the pump. I have done many Chevy's that are electrical problems.

Need to replace the fuel pump on 2002 chevy impala


There are two ways. One is to pull the fuel pump fuse or relay and run the engine until it stalls out. The second is to open the Schrader valve at the end of the fuel rail and bleed the pressure off. This is messier and will cause some fuel spillage, so have a rag ready to catch it.
