2006 Ford F150 Fuel Pump Fuse: Location, Diagram, and Troubleshooting Guide

If your 2006 Ford F-150 cranks but will not start, or if it stalls while driving, the fuel pump fuse is one of the first things you should check. The fuel pump fuse for the 2006 F-150 is located in the passenger compartment fuse panel, which sits under the right side of the instrument panel in the passenger footwell. Specifically, the fuel pump circuit is protected by fuse #9 (20A) in that panel, which also covers the fuel pump relay, fuel injectors, and the intake manifold runner control on 4.2L engines. This guide walks you through the exact location, the full fuse layout, how to test the fuse, and what to do if the fuse keeps blowing.

Where Are the Fuse Boxes on a 2006 F-150?

The 2006 Ford F-150 has two primary fuse locations, plus an auxiliary relay box. Many owners waste time searching the engine bay for a large fuse block that does not exist on this truck. Here is where each box is actually located:

  1. Passenger Compartment Fuse Panel (Central Junction Box) – This is the main fuse panel. It is located under the right side of the instrument panel, in the passenger footwell, behind a removable trim cover. It holds mini fuses numbered 1 through 42, plus high-current cartridge fuses 101 through 118 and fuse 401.

  2. Power Distribution Box (Engine Compartment) – Located in the engine compartment, this box contains high-current fuses and relays that protect the vehicle's main electrical systems. Some sources place it on the right side of the engine bay near the battery, while others note that the fuel pump relay is found in the main fuse panel under the hood.

  3. Auxiliary Relay Box – Located in the engine compartment on the left fender. It holds one 5A fuse, four relays, and two diodes. Nothing in this box fails often.

Important: The fuses you are most likely to change—including the fuel pump fuse—are almost all in the cab panel (passenger footwell), not under the hood.

Which Fuse Controls the Fuel Pump on a 2006 F-150?

The fuel pump circuit on the 2006 F-150 is protected by fuse #9, a 20A mini fuse, located in the passenger compartment fuse panel. This fuse also protects the fuel pump relay, fuel injectors, and the intake manifold runner control (on 4.2L engines).

In addition to fuse #9, the fuel pump relay itself is located in the engine compartment power distribution box, often labeled "FUEL PUMP" or "PUMP". The relay controls the high-pressure fuel pump and is a common starting point for fuel-delivery troubleshooting.

Note: On some 2004–2014 F-150 models, the fuel pump fuse (Fuse 27) in the engine bay fuse box is known to overheat and melt due to undersized terminals. However, this specific problem is most commonly reported on 2009–2014 models, not the 2006 model year. Still, it is worth knowing about if you are diagnosing repeated fuse failures.

How to Access the Passenger Compartment Fuse Panel

Follow these steps to open the passenger compartment fuse panel on your 2006 F-150:

  • Step 1: Open the front passenger door.
  • Step 2: Look under the right side of the dashboard, in the passenger footwell. You will see a trim panel covering the fuse box.
  • Step 3: Pull the trim panel off carefully. It is held in place by clips.
  • Step 4: Find the pull tab on the fuse box cover and lift the cover away.
  • Step 5: On the underside of the fuse panel cover, there is a diagram that identifies each fuse and its amperage rating. Use this diagram to locate fuse #9.

How to Test the Fuel Pump Fuse

Testing the fuel pump fuse is simple and takes less than a minute. Here is what you need to do:

  • Visual inspection: Pull fuse #9 out of the panel. Look through the transparent plastic body. If the metal filament inside is broken or melted, the fuse is blown.
  • Use a test light or multimeter: Set your multimeter to the continuity or ohms setting. Touch one probe to each of the two metal prongs on the fuse. If you get a reading near zero ohms, the fuse is good. If you get no reading (infinite resistance), the fuse is blown.
  • Swap test: If you are unsure, replace fuse #9 with a known-good 20A fuse from another slot (such as fuse #2, which is also 20A, if that circuit is not critical at the moment).

What to Do If the Fuel Pump Fuse Keeps Blowing

A blown fuse is not always the root cause. If you replace fuse #9 and it blows again quickly, there is an underlying problem. Here are the most common causes, in order of likelihood:

  1. Faulty fuel pump relay. The fuel pump relay in the engine bay power distribution box can fail mechanically or electrically. A failed relay can cause the fuel pump to draw excessive current, blowing the fuse. Test by swapping the fuel pump relay with an identical relay (such as the horn relay) in the same box.

  2. Wiring or connector issues. Corroded, frayed, or disconnected wiring near the fuel tank can cause shorts. Pay special attention to the connector on top of the fuel pump module inside the tank.

  3. Failing fuel pump. A fuel pump that is drawing too much current due to wear or internal damage can blow the fuse. If the pump is the problem, it will need to be replaced.

  4. Fuel pump inertia switch activated. The 2006 F-150 has an inertia switch that cuts power to the fuel pump in the event of a collision. This switch can trip accidentally from a hard jolt or rough driving. It is typically located in the passenger footwell behind a panel. Press the button firmly until it clicks to reset it. Note that this switch does not blow the fuse, but it will stop the pump from running even with a good fuse.

  5. Corroded Fuel Pump Driver Module (FPDM). On many 2004–2014 F-150s, the FPDM (located near the spare tire under the truck) suffers from galvanic corrosion, which can cause intermittent fuel pump operation or total failure. An upgraded FPDM with rubber standoffs (such as the Dorman 590-001) prevents this corrosion.

Other Fuses Related to the Fuel System

Besides fuse #9, there are other fuses and relays that affect fuel delivery on the 2006 F-150:

  • Fuel pump relay: Located in the engine compartment power distribution box. Labeled "FUEL PUMP" or "PUMP".
  • PCM power fuses (29, 30, 34): These 15A fuses supply power to the Powertrain Control Module, which controls the fuel injection system.
  • Fuel injector fuse (part of fuse #9 circuit): Fuse #9 also protects the fuel injectors, so a blown fuse will stop fuel delivery entirely.
  • PCM relay coil fuse (fuse 12, 5A): This fuse powers the PCM relay coil, which is part of the fuel system control circuit.

If you have checked fuse #9 and the fuel pump relay, and the pump still does not run, the problem may be the fuel pump itself or the wiring between the relay and the pump.

Step-by-Step Fuel Pump Diagnosis

If your F-150 cranks but will not start, follow this order of checks:

  • Turn the ignition to "II" (ON position) without starting the engine.
  • Listen carefully for a humming sound from the fuel tank area. The fuel pump should prime for one to two seconds. If you do not hear anything, the pump is not getting power.
  • Check fuse #9 in the passenger compartment panel. Replace if blown.
  • Check the fuel pump relay in the engine bay power distribution box. Swap with an identical relay to test.
  • Check the inertia switch in the passenger footwell. Press the reset button.
  • Check the FPDM near the spare tire for corrosion. Clean or replace if needed.
  • If all of these check out, the fuel pump itself is likely defective and will need to be replaced by a professional mechanic.

Fuel Pump Replacement Considerations

The fuel pump on the 2006 F-150 is located inside the fuel tank. Replacing it is a more involved job that typically requires either removing the rear seat cushion and accessing an access panel, or dropping the fuel tank from underneath. If you are not comfortable with this level of repair, it is best to have a professional mechanic handle the replacement.

Final Thoughts

The 2006 Ford F-150 fuel pump fuse is a 20A mini fuse located at position #9 in the passenger compartment fuse panel, under the right side of the dashboard. Checking and replacing this fuse is one of the easiest diagnostic steps you can take when the truck cranks but will not start. If the fuse keeps blowing, move on to the fuel pump relay, the inertia switch, the FPDM, and finally the fuel pump itself.

Remember: the fuse box under the hood of the 2006 F-150 does not hold the fuses you will most likely need to change. The cab panel in the passenger footwell is where almost all the action happens. Keep this guide handy, and you will be back on the road in no time.
