To change the fuel pump in a 2001 Cadillac DeVille, first, relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Next, disconnect the battery, then lift the rear seat to access the fuel pump access panel. Remove the panel, disconnect the fuel lines and electrical connectors from the pump, and then unbolt the pump assembly from the tank. After replacing the pump, reassemble everything in reverse order, ensuring all connections are secure before reconnecting the battery and testing the system.
