To find it, you need to:
1. Consult your owner's manual: This is the best place to start. The manual will have a diagram of your fuse box, showing the location and amperage of each fuse.
2. Locate the underhood fuse box: It's usually a black plastic box under the hood, often near the battery.
3. Check the fuse box diagram: Once you've located the box, open it and look for the diagram on the inside of the lid. This diagram shows which fuse controls what circuit.
4. Look for fuses labeled related to fuel: As mentioned, it might not be explicitly "Fuel Pump". Look for anything relating to fuel injection, the fuel system, or the engine control module (ECM).
5. If you can't find it: Check for a second fuse box, usually located inside the passenger compartment (often under the dash). This is less likely to contain the fuel pump fuse, but it's worth checking if the underhood box doesn't have it.
If you still can't find it after checking these places and your owner's manual, taking your Ranger to a mechanic or an auto parts store for assistance would be best. They have access to more detailed diagrams and can help identify the fuse without causing any further problems.
