2001 Ford Explorer Fuel Pump Fuse Location: A Complete Guide

If you own a 2001 Ford Explorer and your engine cranks but won't start, the fuel pump fuse is one of the first things you should check. The fuel pump fuse for the 2001 Ford Explorer is located in the Power Distribution Box under the hood, on the driver's side of the engine compartment. It is a 20-amp mini fuse, and in most models, it is labeled as fuse #9 or #26, depending on the specific trim and engine configuration . For the 2001 Ford Explorer Sport, the fuse is also found in the passenger compartment fuse box under the dashboard, but the primary location for the fuel pump fuse is the under-hood box . Knowing exactly where to look and how to test it can save you time and money.

Where Is the Fuel Pump Fuse on a 2001 Ford Explorer?

The 2001 Ford Explorer was produced in several trims, including the base model, XLS, XLT, Eddie Bauer, and the Sport model. While the fuse box locations are similar, the exact fuse number for the fuel pump can vary slightly. Let's break it down by the most common configurations.

Under-Hood Power Distribution Box

The main fuse box for the engine and fuel system is located in the engine compartment on the left side (driver's side). This is called the Power Distribution Box (PDB). According to the official fuse box diagrams, the fuel pump fuse is typically a 20-amp mini fuse:

  • For the 2001 Ford Explorer 4.0L engine: This fuse is mini fuse #9 (20A) in the Power Distribution Box . It powers the fuel pump relay and the RAP (Remote Anti-Theft Personality) module.
  • For the 2001 Ford Explorer Sport: The fuel pump fuse is mini fuse #23 (20A, yellow) in the Power Distribution Box .
  • For the third-generation 2001 Explorer (2002 model year): The fuel pump fuse is fuse #26 (20A) in the engine compartment fuse box .

Passenger Compartment Fuse Box

Some sources indicate that the fuel pump fuse for the 2001 Ford Explorer Sport is also located in the passenger compartment fuse box, under the dashboard to the left of the steering wheel. In this box, it is marked as "FPUMP" . To access it:

  1. Open the passenger door.
  2. Remove the trim panel under the dashboard.
  3. Locate the fuse box.
  4. Identify the fuel pump fuse marked "FPUMP."

However, most official diagrams and repair guides point to the under-hood Power Distribution Box as the primary location for the fuel pump fuse .

Fuel Pump Relay Location

In addition to the fuse, the fuel pump relay is another critical component. If the relay fails, the fuel pump won't receive power even if the fuse is good.

  • Relay #5 in the Power Distribution Box (engine compartment) is the fuel pump relay for the 2001 Ford Explorer 4.0L .
  • Relay #48 or 50B are also used as fuel pump relays in some models .
  • For the 2001 Ford Explorer Sport Trac, the fuel pump relay is located in the under-hood fuse box .

The relay is a small, rectangular box that you can swap with a known good relay (like the horn relay) to test if it's faulty.

How to Test the Fuel Pump Fuse

Testing the fuel pump fuse is simple and requires only a few tools:

  1. Turn off the engine and remove the key.
  2. Open the hood and locate the Power Distribution Box on the driver's side.
  3. Remove the cover of the fuse box. The cover usually has a diagram on the back.
  4. Find the fuel pump fuse (fuse #9, #23, or #26, depending on your model).
  5. Pull the fuse out using a fuse puller or needle-nose pliers.
  6. Inspect the metal strip inside the fuse. If it is broken or melted, the fuse is blown.
  7. Replace with a new 20-amp mini fuse if the fuse is bad. Never use a higher amperage fuse, as it can damage the wiring.

If the fuse looks good but the fuel pump still doesn't work, you may need to check the fuel pump relay or the fuel pump itself.

What About the Inertia Switch?

Some 2001 Ford Explorer models have an inertia (fuel shut-off) switch that cuts power to the fuel pump in the event of a collision. This switch is located in the right front passenger footwell, near the kick panel . If the switch is tripped, the fuel pump won't run. To reset it, press the button on top of the switch. However, the 2001 Ford Explorer Sport does not have a manual reset switch; the fuel pump is controlled electronically by the Powertrain Control Module (PCM) .

Common Symptoms of a Blown Fuel Pump Fuse

If your fuel pump fuse is blown, you may experience one or more of the following symptoms:

  • Engine cranks but won't start – This is the most common symptom.
  • No fuel pump noise – When you turn the key to the "ON" position, you should hear a brief whirring sound from the fuel pump (usually from the rear of the vehicle). If you don't hear it, the pump isn't getting power.
  • Stalling while driving – A blown fuse can cause intermittent power loss to the fuel pump.
  • Check Engine Light – A faulty fuel pump circuit can trigger a diagnostic trouble code.

Why Does the Fuel Pump Fuse Blow?

Several issues can cause the fuel pump fuse to blow repeatedly:

  1. Short circuit in the fuel pump wiring – Damaged or chafed wires can cause a direct short.
  2. Faulty fuel pump – A failing pump can draw excessive current, blowing the fuse.
  3. Corroded connectors – Moisture and corrosion can create resistance and heat, leading to fuse failure.
  4. Bad fuel pump relay – A stuck relay can keep the pump running continuously, overheating the circuit.

If you replace the fuse and it blows again immediately, have the system inspected by a professional.

Step-by-Step: Replacing the Fuel Pump Fuse

Here's a quick guide to replacing the fuel pump fuse on a 2001 Ford Explorer:

  1. Disconnect the battery – Ford recommends disconnecting the negative battery terminal before working on the Power Distribution Box . This prevents accidental shorts and allows the system to reset.
  2. Locate the fuse – Refer to the diagram on the fuse box cover or your owner's manual.
  3. Remove the old fuse – Use a fuse puller or pliers to gently pull the fuse straight out.
  4. Install the new fuse – Insert a new 20-amp mini fuse (yellow) into the same slot.
  5. Reconnect the battery – Reconnect the negative terminal.
  6. Test the system – Turn the key to the "ON" position and listen for the fuel pump priming sound. If you hear it, the repair is successful.

Important Safety Notes

  • Always use the correct amperage fuse. Using a 30-amp fuse in place of a 20-amp fuse can cause the wiring to overheat and catch fire.
  • Do not use a fuse with a broken or corroded strip. Even if it looks intact, a damaged fuse may not work properly.
  • If the fuse blows again immediately, there is a deeper electrical issue. Do not keep replacing the fuse; have the vehicle diagnosed by a mechanic.
