Its a simple system to reprogram. you should use a charger on the battery as it can take up to 30 minutes. turn the key on for 10 min until the theft light stops flashing. repeat this 2 more times and after the 3rd cycle., the programing should be complete

Your car has pass lock I, this is an easy fix. Simply attempt to start the car. The theft light will come on and may flash. Leave the key on after you try to start it for about 10 mintues. IF indeed it is a passlock I issues it will relearn and start up after 10minutes. If at anytime the key is turned back off after the intial start, the process must be restarted. Pass lock allows fuel to make it to the injectors and then pulse enough to get engine RPM to around 800 and then shuts the off injectors not the fuel pump. Let me know how you make out.

SOURCE: my chevy cavalier 2000 has a theft system light on

Put key in ignition, turn to on (do not start) position for exactly 10 minutes. As SOON as the light turns off, start car.

This is a problem with most gm vehicles. The vault is the computer.

SOURCE: replace a fuel pump on 2000 chevy cavalier

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.

You have to do a relearn procedure on the anti-theft system:

Attempt to start the vehicle. Leave the ignition on until the THEFT SYSTEM indicator turns off (about 10 minutes). Turn the ignition switch off. Leave the ignition switch off with key in for about 10 minutes. Attempt to start vehicle.
