2000 Expedition Fuel Pump Fuse: Location, Symptoms, and Replacement Guide

The bottom line: If your 2000 Ford Expedition is experiencing fuel pump issues, the first thing to check is the fuel pump fuse. A blown fuse is the most common and easiest fix, often costing less than $10 and taking just a few minutes to replace. If the fuse is fine but the pump still won't run, you likely need a new fuel pump assembly. This guide covers everything you need to know about the 2000 Expedition fuel pump fuse, including where it is, how to test it, and what to do when replacing the fuse doesn't solve the problem.

Understanding the 2000 Expedition Fuel Pump Fuse

The fuel pump fuse on a 2000 Ford Expedition is a small but critical component. It protects the fuel pump circuit from electrical overload. When too much current flows through the circuit, the fuse blows, cutting power to the fuel pump. This prevents damage to the wiring or the pump itself.

The fuel pump fuse is located in the under-hood fuse box, also called the power distribution box. On the 2000 Expedition, this box is on the driver's side, near the battery. Open the black plastic cover, and you will see a diagram on the inside of the lid. Look for the fuse labeled "Fuel Pump" or "FP." It is usually a 20-amp or 30-amp fuse, depending on your specific engine and trim level.

Common symptoms of a blown fuel pump fuse include:

  • The engine cranks but does not start.
  • No fuel pressure at the fuel rail.
  • The fuel pump does not make a humming sound when you turn the key to the "ON" position.
  • The check engine light may come on with codes related to fuel system issues.

How to Test the 2000 Expedition Fuel Pump Fuse

Testing the fuel pump fuse is straightforward. You do not need any special tools, though a multimeter or a test light can help.

Step 1: Locate the fuse box. Open the hood and find the fuse box on the driver's side. Remove the cover by pressing the tabs on the sides.

Step 2: Identify the fuel pump fuse. Look at the diagram on the inside of the fuse box cover. It will list each fuse by number and function. The fuel pump fuse is typically labeled "Fuel Pump" or "FP." If you cannot find it, consult your owner's manual.

Step 3: Visually inspect the fuse. Pull the fuse out using the fuse puller tool included in the fuse box. Hold it up to the light. If the metal strip inside the fuse is broken or melted, the fuse is blown.

Step 4: Use a multimeter for a more accurate test. Set your multimeter to the continuity or resistance setting. Touch one probe to each of the two metal prongs on top of the fuse. If the meter shows continuity (beeps or shows a low resistance reading), the fuse is good. If it shows no continuity, the fuse is blown.

Step 5: Replace a blown fuse. If the fuse is blown, replace it with a fuse of the exact same amperage. Do not use a higher amperage fuse, as this can cause damage to the wiring or the fuel pump.

What to Do If the Fuse Keeps Blowing

If you replace the fuel pump fuse and it blows again immediately or shortly after starting the engine, you have a deeper problem. A fuse that keeps blowing usually indicates a short circuit or an overloaded circuit.

The most common causes of a repeatedly blown fuel pump fuse on a 2000 Expedition are:

  1. A failing fuel pump. When the fuel pump motor starts to fail, it can draw more current than normal, causing the fuse to blow. This is a clear sign that the pump needs replacement.
  2. Damaged wiring. The wiring harness that runs to the fuel pump can get chafed or damaged, especially where it passes through the frame or near the fuel tank. A short to ground will blow the fuse.
  3. A faulty fuel pump relay. The relay controls power to the fuel pump. If the relay sticks or fails, it can cause the pump to run continuously, overheating the circuit.
  4. Corrosion or loose connections. Over time, corrosion can build up on the fuse terminals or the relay contacts, increasing resistance and causing the fuse to blow.

Replacing the Fuel Pump on a 2000 Expedition

If the fuse is good but the pump still does not run, or if the fuse keeps blowing, you likely need to replace the fuel pump. The fuel pump is located inside the fuel tank. Replacing it involves dropping the fuel tank or accessing it through a service panel in the cargo area.

Here is a general overview of the replacement process:

  • Safety first: Disconnect the negative battery cable. Relieve fuel system pressure by removing the fuel pump fuse and cranking the engine for a few seconds. Work in a well-ventilated area with no open flames.
  • Remove the fuel tank: On the 2000 Expedition, the fuel tank is mounted under the vehicle. You will need to drain the tank, disconnect the fuel lines and electrical connector, and remove the straps that hold the tank in place.
  • Remove the fuel pump assembly: Once the tank is lowered, you can access the fuel pump module. It is held in by a locking ring. Turn the ring counterclockwise to remove it.
  • Install the new pump: Pull the old pump assembly out. Transfer the fuel level sender and any other components to the new pump assembly. Install the new pump, replace the locking ring, and reinstall the tank.
  • Test the system: Reconnect the battery, install the correct fuse, and turn the key to the "ON" position. You should hear the fuel pump hum for a few seconds. Check for leaks before starting the engine.

Common Questions About the 2000 Expedition Fuel Pump Fuse

Q: Can I drive with a blown fuel pump fuse?
No. If the fuel pump fuse is blown, the pump will not run, and the engine will not start. You will be stranded until the fuse is replaced.

Q: How much does a fuel pump fuse cost?
A standard 20-amp or 30-amp fuse costs less than $5 at any auto parts store. It is one of the cheapest repairs you can do.

Q: Can a bad fuel pump relay cause a blown fuse?
Yes. A stuck relay can keep the fuel pump running continuously, which can overload the circuit and blow the fuse. Always check the relay if the fuse keeps blowing.

Q: How long does a fuel pump last on a 2000 Expedition?
The average lifespan of a fuel pump is 100,000 to 150,000 miles. Many factors affect this, including fuel quality, driving habits, and how often you run the tank low on fuel.

Q: What other fuses should I check if the fuel pump doesn't work?
Check the main engine fuse, the PCM (powertrain control module) fuse, and the ignition fuse. A blown fuse in any of these circuits can also prevent the fuel pump from receiving power.

Tips for Preventing Fuel Pump Problems

Keep your fuel tank at least a quarter full at all times. Running the tank low can cause the fuel pump to overheat, as the fuel inside the tank cools the pump. Low fuel also means more sediment and debris can enter the pump, wearing it out faster.

Change your fuel filter regularly. A clogged fuel filter puts extra strain on the fuel pump. For the 2000 Expedition, the fuel filter is located along the frame rail on the driver's side. Replace it every 30,000 miles or as recommended in your owner's manual.

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 unusual noises. If you hear a whining or humming sound from the rear of the vehicle, especially when accelerating, the fuel pump may be starting to fail. Replace it before it leaves you stranded.

Final Thoughts on the 2000 Expedition Fuel Pump Fuse

The fuel pump fuse is a simple but essential part of your 2000 Ford Expedition. Always start your diagnosis by checking the fuse. It is the quickest, cheapest, and easiest fix. If the fuse is fine, move on to testing the relay and the pump itself. When you need a new fuel pump, choose a high-quality replacement like KEMSO for peace of mind and long-term reliability.

Remember, a blown fuse is not the end of the world. It is a warning sign that something in the fuel system needs attention. Address it promptly, and your Expedition will keep running for many more miles.
