To find the correct fuse and relay:
1. Consult your owner's manual: This is the best place to start. It will have a fuse box diagram showing the location and amperage of all fuses, including those related to the fuel system.
2. Check the fuse box under the hood: Many Ford Explorers have a fuse box under the hood. Look for fuses labeled "Fuel Pump" or something similar, or follow the diagram in your owner's manual.
3. Locate the fuel pump relay: The relay is often located in the under-hood fuse box as well. It might be labeled "Fuel Pump Relay" or something similar. Check the diagram for its location.
4. Find the inertia switch: This is usually located in the passenger compartment, often under the dash or in the glove box area. It's a small, usually red, switch that can be reset by pressing a button. A tripped inertia switch will prevent the fuel pump from operating.
Important Note: Before working on any electrical components, disconnect the negative battery terminal to avoid electrical shocks or short circuits.
If you can't locate the fuse or relay using your owner's manual, a Ford repair manual specific to your year and model will provide detailed diagrams and instructions. You may also want to consult a qualified mechanic if you're not comfortable working with car electrical systems.
