* Under the hood fuse box: Check your owner's manual. This is the most likely location, but the fuse may be labeled something other than just "fuel pump." It might be part of a larger circuit (like "Engine Control Module" or similar).
* Passenger compartment fuse box: Some models placed it in the fuse box inside the vehicle. Again, check your owner's manual.
* In the Power Distribution Box (PDB): This is a larger box often located near the battery and contains larger fuses and relays. This is less likely for the fuel pump itself, but it *could* control a relay that activates the fuel pump.
To find it reliably:
1. Consult your owner's manual: This is the most crucial step. The manual will have a diagram of the fuse boxes showing the fuse locations and what each fuse protects.
2. Check online forums: Search online forums specifically for "1999 Ford Explorer fuel pump fuse location" Include your specific engine size (e.g., 4.0L V6, 5.0L V8) for better results.
Important Safety Note: Before working with fuses or any electrical components in your vehicle, disconnect the negative terminal of your battery to avoid accidental short circuits and injury.
