To replace the fuel pump on a 2003 Nissan Frontier, start by disconnecting the negative battery terminal to ensure safety. Then, relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls. Next, access the fuel pump by removing the rear seat or the access panel in the bed, disconnect the fuel lines and electrical connectors, and unbolt the pump assembly. Finally, replace the old pump with the new one, reassemble everything, and reconnect the battery.
