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.

And it is located inside your cars gas tank. To remove your fuel pump from your 2000 Chevy Cavalier you will have to drop and remove the gas tank to get to it. Unfortunately there is no access port to make it easy on this model of car.

I HAVE A 2000 CHEVY CAVALIER AND I WON'T STAY RUNNING. YOU HAVE TO PUMP THE GAS PEDAL WHILE TURNING THE IGNITION TO GET IT TO START UP. AND IF YOU TAKE YOUR FOOT OFF THE GAS IT KILLS THE ENGINE.


sounds like the fuel filter may be cloged or the fuel pump may be getting weak. have a fuel rail pressure test done. that will help diagnose the fuel system.

2000 Chevy Cavalier will not start after accident


there is a g force sensor in the fender. there is a fuel shutoff system in place to shut off the fuel pump in case of an accident on most newer cars.
i would call gm and ask if that is the case with your car.
same thing applies if the airbags are deployed.

Cavalier dies


you need to find the fuel pressure release around the fuel rail press the little tab when the car dies. If there is no fuel coming out from that point, your fuel pump is going.
