2000 Ford Expedition Fuel Pump Fuse Location: A Complete Guide

The bottom line: The fuel pump fuse on a 2000 Ford Expedition is located in the under-hood fuse box (Power Distribution Box). It is a 20-amp fuse, typically labeled as Fuse #22 or Fuse #23, depending on the specific configuration. If your Expedition cranks but won't start, checking this fuse is the first and easiest step before replacing the fuel pump itself.

Where Is the Fuse Box Located?

The 2000 Ford Expedition has two main fuse boxes, but the fuel pump fuse is in the one under the hood, not the one inside the cabin. To find it:

Step 1: Open the hood. The fuse box is on the driver’s side, near the battery, mounted on the inner fender. It is a black plastic box with a removable cover.

Step 2: Remove the cover. The cover may have a diagram on the inside that shows fuse locations, but it is often faded or hard to read after 20+ years. If the diagram is missing, use the following guidance.

Step 3: Identify the fuel pump fuse. Look for a 20-amp fuse in the box. On most 2000 Expeditions, the fuel pump fuse is in position #22. Some sources show it as position #23 in certain trim levels. The fuse is typically yellow (for 20-amp) or orange (for 20-amp in some aftermarket replacements). The fuse box cover should have a label like "Fuel Pump" or "FP."

How to Check the Fuel Pump Fuse

Testing the fuse does not require any special tools. Here is how to do it:

1. Visual inspection: Pull the fuse out using a fuse puller (usually found inside the fuse box or in the vehicle's tool kit). Hold it up to the light. If the metal strip inside is broken, blackened, or melted, the fuse is blown.

2. Multimeter test: If you have a multimeter, set it to continuity mode or resistance mode. Touch the probes to the two small metal prongs on top of the fuse. If the meter beeps or shows near-zero resistance, the fuse is good. If it shows infinite resistance, the fuse is blown.

3. Swap test: If you have a spare 20-amp fuse, swap it in and see if the vehicle starts. If it starts, the original fuse was blown.

What If the Fuse Is Blown?

If the fuel pump fuse is blown, do not simply replace it and forget about it. A blown fuse is a symptom, not the root cause. Common reasons the fuse blows include:

A shorted fuel pump: The pump motor itself has failed internally, drawing too much current and blowing the fuse. This is the most common cause.

A wiring issue: A chafed wire rubbing against the frame or a corroded connector can cause a short circuit. The fuel pump wiring runs from the fuse box, under the vehicle, to the fuel tank. Over time, road salt and moisture can damage the wires.

A faulty fuel pump relay: While less common, a stuck relay can keep power flowing to the pump even when the engine is off, causing the fuse to overheat and blow.

Warning: If you replace the fuse and it blows again immediately or within a few miles, do not keep replacing fuses. This indicates a serious electrical problem that needs professional diagnosis. Continuing to replace fuses can damage the wiring harness or the PCM (Powertrain Control Module).

Fuel Pump Relay Location

If the fuse is good but the pump still doesn't run, the next suspect is the fuel pump relay. On the 2000 Ford Expedition, the fuel pump relay is also located in the under-hood fuse box. It is usually a mini-relay (a small square black box) that is labeled "Fuel Pump Relay" or "FP."

To test the relay:

1. Swap test: Find a relay of the same type in the fuse box (e.g., the horn relay or the starter relay). Swap them. If the fuel pump now works, the original relay was bad.

2. Tap test: With the engine cranking, gently tap the relay with a screwdriver handle. If the pump starts running, the relay contacts are worn and the relay needs replacement.

Other Common Symptoms of a Bad Fuel Pump Fuse

Before you start digging into the fuse box, watch for these signs that point to a fuel pump electrical issue:

Engine cranks but won't start: This is the classic symptom. You hear the starter motor turning the engine over, but the engine never fires. If the fuel pump isn't getting power, no fuel reaches the injectors.

No whining sound from the fuel tank: When you turn the key to the "ON" position (without cranking), you should hear a faint whining or buzzing sound from the rear of the vehicle for about 2 seconds. This is the fuel pump priming the system. If you don't hear this, the pump is not getting power.

Sporadic stalling: A loose fuse or a failing relay can cause the fuel pump to lose power intermittently, leading to the engine stalling while driving, especially under load or on hills.

Check Engine Light: A fuel pump electrical fault may trigger a diagnostic trouble code (DTC) such as P0230 (Fuel Pump Primary Circuit Malfunction) or P0231 (Fuel Pump Secondary Circuit Low).

Step-by-Step Troubleshooting Flow

If your 2000 Ford Expedition won't start, follow this logical order:

1. Check the 20-amp fuel pump fuse in the under-hood fuse box (position #22 or #23).

2. If the fuse is good, swap the fuel pump relay with a known good relay.

3. If the relay is good, check for voltage at the fuel pump connector. You can probe the connector at the top of the fuel tank (after removing the rear seat cushion and access panel) while someone turns the key to ON.

4. If no voltage is present, the problem is in the wiring between the fuse box and the fuel pump, or the ground circuit is broken.

5. If voltage is present but the pump doesn't run, the fuel pump itself is likely dead and needs replacement.

Why You Should Replace the Fuel Pump, Not Just the Fuse

If you find that the fuse is blown and you replace it, only to have it blow again after a few days, the fuel pump is almost certainly the culprit. A failing fuel pump motor draws more current as its bearings wear out, eventually exceeding the fuse rating.

Replacing just the fuse is a temporary fix that can leave you stranded. Once the pump starts to fail, it will continue to degrade. The best long-term solution is to replace the fuel pump with a high-quality aftermarket unit.
