WARNING: This page is about a different car, the 2004 GMC Sierra and 2004 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
    IMPORTANT: The engine oil may be contaminated with fuel if the fuel injectors are leaking.
  1. Remove the fuel meter body. Refer to Fuel Meter Body Assembly Replacement .

    NOTE: Use care in removing the fuel injectors to prevent damage to the electrical connector terminals.
    The fuel injector is serviced as a complete assembly only.
    Also since the injectors are electrical components, these injectors should not be immersed in any type of liquid solvent or cleaner as damage may occur. Fuel injector cleaning is not recommended.
  4. While pulling the fuel injector downward, push with a small tip punch down between the injector terminals until the injector is removed.
