How do you change a fuel pump on a 1994 Plymouth Sundance?

To change the fuel pump on a 1994 Plymouth Sundance, first, relieve the fuel system pressure by removing the fuel pump relay and starting the engine until it stalls. Next, disconnect the battery and remove the fuel tank to access the pump. Once the tank is out, detach the fuel lines and electrical connectors from the pump, then remove the old pump and install the new one. Reassemble everything, ensuring all connections are secure, and test the system before re-installing the fuel relay.
