The fuel pump relay is located in the engine bay fuse box, number 43 on the 2002 Ford Explorer Sport Trac. The fuel pump relay is an electronic component that is found on virtually all vehicles equipped with an internal combustion engine. It functions as the primary electronic switch that controls power to the fuel pump. The relay can fail due to several reasons, from dust to electrical power surges, anything can affect the well-being of a fuel pump relay. Both dust and sudden voltage increases can influence a fuel pump relay's performance and cause the vital function of an engine to malfunction.
