2001 Ford Focus Fuel Pump Fuse Location: Complete Guide

The bottom line: The fuel pump fuse on a 2001 Ford Focus is located in the power distribution box under the hood, and it is fuse number 12, rated at 15 amps. If your Focus cranks but won't start, a blown fuel pump fuse is one of the first things you should check. This guide will walk you through exactly where to find it, how to inspect it, and what to do if it's blown.

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

The 2001 Ford Focus has two fuse boxes: one inside the passenger compartment and one under the hood. The fuel pump fuse is not in the cabin - it's in the engine compartment.

The power distribution box (engine compartment fuse box) is located in the engine bay, near the battery and behind the air box. To access it:

1. Open the hood and secure it with the prop rod.
2. Look toward the back of the engine bay, behind the air filter housing.
3. You will see a black rectangular box with a locking tab on the rear side.
4. Pull up on the lock tab and lift the cover to access the fuses.

On the back of the fuse box cover, there is a diagram or legend that shows which fuse protects which circuit. The fuel pump is protected by fuse number 12, which is a 15 amp fuse.

How to Check the Fuel Pump Fuse

Checking a fuse is simple and takes less than five minutes. Here is what you need to do:

Step 1: Locate the power distribution box. As described above, it is under the hood behind the air box.

Step 2: Remove the fuse box cover. Pull up on the lock tab and lift the cover. Set it aside where you can see the legend on the back.

Step 3: Find fuse number 12. Look at the diagram on the back of the cover or inside the fuse box itself. Fuse 12 is a 15 amp fuse. It is usually a small, rectangular plastic piece with two metal prongs.

Step 4: Remove the fuse. You can use the plastic fuse puller tool that is often stored inside the fuse box cover. If you don't have the tool, a pair of needle-nose pliers works just as well. Grip the fuse firmly and pull it straight out.

Step 5: Inspect the fuse. Hold the fuse up to the light. Look through the clear plastic body at the metal strip inside. If the strip is intact and continuous, the fuse is good. If the metal strip is broken, melted, or separated, the fuse is blown and needs to be replaced.

Step 6: Replace the fuse if needed. If the fuse is blown, replace it with a new 15 amp fuse of the same type. Do not use a higher amp fuse, as this can cause electrical damage or a fire.

What Does the Fuel Pump Fuse Do?

The fuel pump fuse protects the electrical circuit that powers the fuel pump. When you turn the key to the "on" position, the fuel pump relay sends power through this fuse to the fuel pump. The pump then pressurizes the fuel system so the engine can start and run.

If the fuse blows, the fuel pump stops receiving power, and the engine will not start. You may hear the engine crank but it will not fire up. This is a classic symptom of a blown fuel pump fuse.

Other Possible Causes of a No-Start Condition

If the fuse is good but your 2001 Ford Focus still won't start, there are other components to check:

Fuel pump relay. The fuel pump relay is also located in the power distribution box under the hood. It is labeled as relay R7. A bad relay can prevent the fuel pump from getting power even if the fuse is good.

Inertia fuel shut-off switch. The 2001 Ford Focus has an emergency fuel pump shut-off switch that turns off the fuel pump in the event of an accident. This switch is located in the kick panel on the passenger side foot-well. You can access it through a recess in the kick panel. If this switch has been tripped, it will cut power to the fuel pump. Press the reset button on top of the switch to reset it.

Fuel pump itself. If the fuse, relay, and inertia switch are all working properly, the fuel pump itself may have failed. A failing fuel pump often makes a whining noise from the fuel tank area. Other signs include engine hesitation, stalling, and reduced power, especially when accelerating or going uphill.

How to Depressurize the Fuel System Before Working on the Fuel Pump

If you need to replace the fuel pump or any fuel system components, you must first depressurize the fuel system. Here is the safe way to do it:

1. Remove the fuel pump fuse (fuse number 12) from the power distribution box.
2. Start the engine and let it idle until it stalls. This will use up the fuel remaining in the lines.
3. After the engine stalls, crank the engine for a few seconds to make sure all fuel is out of the system.
4. Replace the fuel pump fuse.

Always disconnect the battery ground wire before working on any fuel system components. Fuel is flammable, and a spark from the battery could cause a fire.

Additional Tips for Preventing Fuel Pump Problems

Taking care of your fuel system can extend the life of your fuel pump and prevent unexpected breakdowns.

Keep your gas tank at least a quarter full. Running the tank low can cause the fuel pump to overheat. The pump relies on the fuel in the tank for cooling and lubrication. When the fuel level is low, the pump is not submerged in fuel and can run hotter than it should.

Change your fuel filter regularly. A clogged fuel filter puts extra strain on the fuel pump. The pump has to work harder to push fuel through a dirty filter, which can cause it to fail prematurely. Check your owner's manual for the recommended replacement interval.

Use high-quality fuel. Cheap or contaminated fuel can damage the fuel pump and other fuel system components. Stick to reputable gas stations.

Listen for warning signs. If you hear a whining noise coming from the fuel tank area, especially when you first turn the key on, it could be a sign that the fuel pump is starting to fail. Address the issue early before it leaves you stranded.

Summary

The 2001 Ford Focus fuel pump fuse is fuse number 12 in the engine compartment power distribution box. It is a 15 amp fuse. If your car cranks but won't start, checking this fuse should be one of the first steps in your diagnostic process.

If the fuse is good, move on to checking the fuel pump relay (R7), the inertia shut-off switch in the passenger footwell, and finally the fuel pump itself. Always depressurize the fuel system before working on any fuel components, and disconnect the battery ground wire for safety.
