However, there isn't a single, clearly labeled "fuel pump relay." The relay is often integrated into the system and might be part of a larger relay assembly or controlled indirectly. You'll likely need to consult a wiring diagram specific to your 1995 Ford Explorer (which can often be found online through repair manuals or forums) to identify the correct relay. The diagram will show the relay's location within the PDB and possibly indicate its function through symbols or numbers.
Look for relays that are related to the fuel system (fuel injection, engine control, etc.). You might need to test individual relays with a multimeter to determine which one controls the fuel pump. This is best done with the help of a wiring diagram to avoid damaging the system.
