The fuel pump relay on a 2002 Ford Ranger is in the engine compartment’s fuse/relay box (the Power Distribution Center) on the driver’s side of the engine bay. It is typically labeled FUEL PUMP or FUEL on the lid’s diagram.
In most Ranger configurations from that era, the relay sits among several square relays in the under-hood fuse box near the battery. If the label isn’t obvious, consult the diagram on the inside of the box cover or the owner’s manual to confirm the exact position for your particular engine, such as the 2.3L inline-4 or the 3.0L V6. Some trims can place related relays in a different box, but the engine bay power distribution center is the common location for the 2002 Ranger.
Location in the engine bay
Most 2002 Rangers with the common engines use a Power Distribution Center mounted in the engine compartment. Open the box, read the diagram on the underside of the lid, and locate the position labeled FUEL PUMP or FUEL. The fuel pump relay is a standard four-pin automotive relay.
How to identify the exact slot
If the lid diagram is faded, compare with a repair manual or an online diagram for the 2002 Ranger to confirm which slot corresponds to the fuel pump. The physical relay is the familiar square module about an inch by a bit more than half an inch with four terminals.
Here’s how to locate and identify the fuel pump relay:
- Open the hood and find the engine compartment fuse/relay box (Power Distribution Center), typically on the driver’s side near the fender or battery.
- Remove the lid and study the diagram to find the slot labeled FUEL PUMP or FUEL.
- Take note of the exact relay position (the box will show a number or name for each relay).
- If the diagram is unclear, consult a service manual or Ford’s online diagrams for confirmation of the exact slot for your engine variant (2.3L or 3.0L).
Concluding paragraph: Once you’ve located the relay slot labeled FUEL PUMP, you’re ready to test or replace as needed, following standard electrical safety precautions and ensuring the ignition is off before handling components.
Testing and replacing the relay
To determine if the relay is functioning, you can perform basic checks and, if needed, swap with a known-good identical relay in the same box. If you’re not comfortable performing electrical tests, consider professional help.
- With the ignition off, remove the fuel pump relay and inspect for corrosion, melted plastic, or signs of damage.
- Check the coil resistance with a multimeter. The coil pins (often 85 and 86) typically show a resistance in the tens to hundreds of ohms range depending on the exact relay; consult the service manual for your component’s spec.
- Swap the fuel pump relay with another identical relay in the box (for example, the A/C or IGN relay) to see if the fuel pump primes when the engine is cranked. If swapping fixes the symptom, the original relay is likely faulty.
- If swapping doesn’t help, test the voltage at the fuel pump connector when the ignition is in the RUN position to confirm the signal is reaching the pump, or have a professional diagnose wiring and fuel-pressure concerns.
Concluding paragraph: If the relay proves faulty, replace it with a new, appropriate 4-pin automotive relay of the same amperage rating. If you cannot locate the fuel pump relay or you suspect a more complex electrical issue, timing and fuel-system diagnostics by a qualified technician are advised.
Note: Some 2002 Ranger trims or VIN-specific configurations may place the fuel pump relay in a different box or in the interior fuse panel. If you cannot locate it in the engine bay, consult your owner's manual or a Ford service database for the exact location corresponding to your vehicle’s engine and trim.
Summary
For most 2002 Ford Rangers, the fuel pump relay lives in the engine bay’s under-hood fuse/relay box (Power Distribution Center), labeled FUEL PUMP on the lid diagram. Locate the box, read the diagram, and identify the proper slot. If trouble arises, you can test or swap the relay with another identical relay to diagnose, but proceed with safety and consider professional help if unsure.

Which Ford Ranger engine is best?
Engine and performance differences
This means you get a more muscular drive from the 3.2L, while the 2.2L offers smoother, more efficient driving. Naturally, the 3.2L Ford Ranger will be more capable at towing or carrying weight, but the 2.2L will give you better mpg if that's something you value.
