To change the fuel pressure regulator in a 2004 Olds Alero, first relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Disconnect the battery, then remove the fuel rail by loosening the bolts and gently pulling it away from the intake manifold. Detach the old fuel pressure regulator from the fuel rail, install the new regulator, and reassemble everything, ensuring all connections are secure. Finally, reconnect the battery and fuel pump relay, then start the engine to check for leaks.
