* Under the hood in the Power Distribution Box (PDB): This is the most common location. The PDB is usually a large black plastic box located near the battery. Look for a diagram on the inside of the cover to identify the relay. The relay may be labeled, or you may need to consult a wiring diagram to find the correct one.
* Inside the passenger compartment fuse box: Less common, but possible on some 2001 Ranger models. This fuse box is usually located under the dash on the driver's side. Again, a diagram inside the box cover will be helpful.
To find it reliably:
1. Consult your owner's manual: This is the best place to start. It should have a diagram showing the location of all relays and fuses.
2. Use a wiring diagram: A wiring diagram for your specific year and model Ranger will precisely show the relay's location. You can usually find these online through sites specializing in automotive repair manuals (like Haynes or Chilton) or on online forums dedicated to Ford Rangers.
3. Use a multimeter: If you're comfortable with basic electrical testing, you can trace the fuel pump circuit with a multimeter to find the relay. This is more involved but is a sure way to locate it.
Important Note: Before working on electrical components, always disconnect the negative terminal of your battery to prevent accidental short circuits.
