2001 Ford F150 Fuel Pump Fuse Location: The Complete Guide to Finding, Testing, and Replacing It

The bottom line: The fuel pump fuse on a 2001 Ford F150 is located in the under-hood power distribution box (fuse box) on the driver's side near the battery. It is a 20-amp mini fuse, typically labeled as fuse number 10, and it is the second fuse in the fifth row on the left-hand side . If your truck cranks but won't start, checking this fuse should be one of the first things you do. A blown fuse is a common, inexpensive fix that can save you a trip to the mechanic.

Where Exactly Is the Fuel Pump Fuse Located?

Your 2001 Ford F150 has two fuse boxes. One is inside the cabin under the dashboard on the driver's side, and the other is under the hood. The fuel pump fuse is not inside the cab. It is in the under-hood fuse box, which Ford calls the Power Distribution Box .

Step-by-step to find the fuse box:

1. Open the hood of your F150. Make sure the engine is off and the keys are out of the ignition.
2. Look on the driver's side of the engine compartment. You will see a black plastic box located near the battery and the firewall .
3. Open the box. Press the release tabs on the sides of the cover and lift it off. On the inside of the cover, you should find a diagram that shows the location of each fuse and relay .
4. Find fuse number 10. According to the 2001 Ford F150 owner's manual and multiple fuse box diagrams, the fuel pump fuse is fuse number 10 . It is a 20-amp mini fuse. The diagram on the inside of the cover should clearly label it as "Fuel Pump" or show it as fuse 10 .
5. Check the fuse. The fuse is a small, plastic blade-type fuse. It is usually yellow or clear with the number "20" printed on top .

Important note: Some sources also mention that fuse number 18 in the same under-hood box is a 15-amp fuse that protects the Powertrain Control Module, fuel injectors, and the fuel pump relay . While fuse 10 is the direct power source for the fuel pump, fuse 18 can also cause a no-start condition if it blows. If fuse 10 is good, check fuse 18 as well.

How to Check If the Fuel Pump Fuse Is Blown

Checking a fuse is a simple job that takes less than five minutes. You do not need any special skills to do it.

Step 1: Remove the fuse. Use the fuse puller tool that is usually stored inside the fuse box cover itself. If you don't have a puller, a pair of needle-nose pliers will work. Gently pull the fuse straight out of its slot .

Step 2: Inspect the fuse visually. Hold the fuse up to the light. Look through the clear plastic top. Inside, you should see a thin metal strip that connects the two metal prongs. If that strip is broken, melted, or has a dark spot, the fuse is blown and needs to be replaced .

Step 3: Test the fuse with a multimeter (optional). If you cannot see any damage but still suspect the fuse is bad, you can use a multimeter to test it. Set the multimeter to the continuity setting. Touch one probe to each of the two metal prongs on the top of the fuse. If you hear a beep, the fuse is good. If there is no beep, the fuse is blown .

Step 4: Replace the fuse if needed. If the fuse is blown, replace it with a new 20-amp mini fuse of the same type. Never use a fuse with a higher amperage rating, as this can cause wiring damage or even a fire .

What Happens When the Fuel Pump Fuse Blows?

When the fuel pump fuse blows, the fuel pump receives no power and stops working. This means no fuel is sent to the engine. Here are the exact symptoms you will see :

1. Engine cranks but will not start. This is the most common symptom. The starter motor turns the engine over, but the engine never fires up because there is no fuel.
2. No fuel pressure. If you check the fuel rail (the metal pipe on top of the engine), there will be no pressure when you turn the key to the "ON" position.
3. No sound from the fuel pump. When you turn the key to the "ON" position (without starting the engine), you should normally hear a faint humming sound from the fuel pump for about 2-3 seconds. If you hear nothing, the fuse or the pump itself is dead .
4. Check engine light may come on. The computer detects the loss of fuel pressure and may turn on the check engine light. Common trouble codes include P0087 (Fuel Rail Pressure Too Low) or P0231 (Fuel Pump Secondary Circuit Low) .

Why Does the Fuel Pump Fuse Keep Blowing?

If you replace the fuse and it blows again immediately, or within a few days, you have a deeper problem. Do not keep replacing the fuse without finding the cause. Here are the most common reasons :

1. Short circuit in the fuel pump wiring. The wires that run from the fuse box to the fuel pump can rub against the metal frame or chassis over time. This wears through the insulation and causes a short circuit. This is a common problem on F150s, especially where the wiring passes near the frame rail .

2. A faulty fuel pump. If the fuel pump itself is failing internally, it may draw too much current and blow the fuse. This is a sign that the pump needs to be replaced .

3. A bad fuel pump relay. The fuel pump relay is a small electronic switch that controls power to the pump. If the relay fails, it can cause the pump to draw too much current or fail to operate correctly. The relay is located in the same under-hood fuse box and is often labeled as relay 301 .

4. Corrosion or damage at the fuse box. Sometimes the fuse box itself can have corrosion or damaged terminals, which can cause a short.

How to Test the Fuel Pump Relay

The fuel pump relay is a small, square component located in the same under-hood fuse box. On the 2001 Ford F150, it is often labeled as relay 301 . A quick way to test if the relay is the problem is to swap it with another relay of the same type in the fuse box. For example, you can swap the fuel pump relay with the horn relay or the A/C clutch relay, which are usually the same rating . If the truck starts after the swap, the relay was bad.

Important: If the truck starts after swapping the relay, do not drive it for long. The relay you swapped in may not be designed for the continuous load of the fuel pump. This is just a diagnostic test.

Other Things to Check If the Fuse and Relay Are Good

If the fuel pump fuse and relay are both good, but the truck still will not start, here are a few other things to check:

1. The inertia fuel shut-off switch. This is a safety switch that automatically cuts power to the fuel pump in the event of a collision. It is located behind an access panel in the right rear quarter trim panel, near the liftgate . If the switch has been tripped, you will need to reset it by pressing the red button on top .

2. The fuel pump itself. If the fuse, relay, and inertia switch are all good, the fuel pump itself may have failed. You can test the pump by using a multimeter to check for power and ground at the pump's electrical connector . If you have power and ground but the pump is silent, it is likely bad.

3. The fuel pressure. Use a fuel pressure gauge to test the pump's output at the Schrader valve on the fuel rail. The pressure should be between 30-60 PSI, depending on the engine type . If the pressure is low or zero, the pump is failing.
