* Under the hood in the power distribution box (fuse box): This is the more common location. The power distribution box is typically located near the battery. The relay itself will be labeled, or you can consult your owner's manual to identify it. Look for a diagram in the manual showing the relay locations.
* Inside the passenger compartment fuse box: Less common, but possible. Again, check your owner's manual for the correct location and relay identification.
To find it definitively:
1. Consult your owner's manual: This is the most reliable source. It will have a diagram of the fuse and relay boxes.
2. Check online forums: Search online forums specific to 1997 Ford Rangers. Owners often discuss issues and solutions, including relay locations.
3. Use a wiring diagram: A wiring diagram for your specific year, engine, and trim level will show the location and circuit for the fuel pump relay. You can often find these diagrams online (some are free, others require a paid subscription to a repair manual database).
Remember to always disconnect the negative battery terminal before working with electrical components in your vehicle.
