To remove fuel injectors from the fuel rail on a 2001 Chevrolet Malibu, first ensure the engine is cool and relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls. Then, disconnect the fuel lines and electrical connectors from the injectors. Remove the bolts securing the fuel rail to the intake manifold, gently lift the rail, and pull out the injectors from the rail. Be careful to avoid damaging the O-rings during removal.
