Where is the fuel pump fuse located in a 1993 mustang lx 5.0?

The fuel pump fuse in a 1993 Mustang LX 5.0 is not a standard fuse. Instead, the fuel pump relay controls the fuel pump. You'll find the fuel pump relay in the underhood fuse box (Power Distribution Box). The exact location within that box varies slightly depending on the specific model year and options, but it's usually clearly labeled "Fuel Pump" or with a similar designation. Consult your owner's manual or a wiring diagram for your specific vehicle to be certain.
