The 2003 Nissan Pathfinder fuel pump relay can be found in the main fuse panel that is under the hood. Finding the relay should be easy if You use the guide that is on the cover of the fuse panel to determine where each item is. If You are having problems with Your fuel pump then the first thing You should change is the relay. You can also unplug and reconnect the relay to reset the fuel pump like a reset switch on older vehicles. If You notice that there is not any fuel pressure at Your engine that is usually a sign of a problem with the pump and if replacing the relay does not fix it then the pump itself may need to be replaced.
