How to Replace a Fuel Pump in an Oldsmobile Aleroby Contributor
The Oldsmobile Alero has an electric fuel pump so you should check its fuses and relays and ensure you have fuel before performing the more difficult task of inspecting the fuel pump. If your vehicle still has difficulty getting fuel you may need to clean or replace the fuel pump. The Oldsmobile Alero's variety of styles and trim levels can affect the replacement fuel pump you choose.
Determine which fuel pump your Oldsmobile Alero will need. This depends not only on the make and model, but also the engine size. An Oldsmobile Alero may have a 2.2 L Ecotec, 2.4 L LD9 or 3.4 LA1 engine.
Prepare your vehicle for fuel pump servicing. Disconnect the negative battery cable with a socket wrench, relieve the fuel system pressure and drain the fuel tank.
Free the fuel sender assembly by removing the snap ring or cam lock ring with fuel sender lock nut tool J-39765, depending on the specific model. Remove the fuel sender assembly and fuel strainer. Disconnect the retainer from the fuel pump and wiring harness.
Release the three tabs on the fuel sender by starting with the one opposite the fuel level sensor and proceeding clockwise. Lift the fuel cover assembly to disconnect the electrical connection from the fuel pump. Remove the fuel pump baffle by rotating it counter-clockwise. Remove the fuel pump outlet seal.
Install the new fuel pump using the items included in the kit and be sure to replace the fuel pump outlet seal.
Complete the installation by reversing the removal procedure.
