To locate it definitively, you'll need to:
1. Consult your owner's manual: This is the best resource. It should have a diagram of the Power Distribution Box showing the location of all relays and fuses.
2. Use a wiring diagram: A wiring diagram specific to your 1997 Ford Explorer will show you the circuit for the fuel pump and the relay involved. You can find these online through repair manuals or automotive parts websites.
3. Use a multimeter: If you're comfortable with basic electrical work, you can use a multimeter to test the relays in the PDB to identify the one that controls the fuel pump. This method requires some knowledge of automotive electrical systems.
Without a diagram or manual, finding the correct relay by visual inspection alone is difficult and unreliable. Using the owner's manual or a wiring diagram is strongly recommended.
