2000 Ford Taurus Fuel Pump Fuse: Location, Diagram, and Troubleshooting Guide

Conclusion First: If your 2000 Ford Taurus is experiencing fuel pump issues, the most common culprit is a blown fuel pump fuse or a faulty fuel pump relay. The fuel pump fuse is located in the engine compartment fuse box, and it's a 20-amp fuse. Checking and replacing this fuse is the first and easiest step before considering a full fuel pump replacement. This guide will walk you through everything you need to know about the fuel pump fuse, relay, and system for your 2000 Ford Taurus, saving you time and money on diagnostics.

Understanding the Fuel Pump Fuse and Relay System

The fuel pump in your 2000 Ford Taurus is an electrical component that requires a steady flow of power to operate. The fuse and relay work together to protect the pump and control its operation. The fuse acts as a safety device, blowing if there's an electrical overload, while the relay is a switch that turns the pump on and off based on signals from the engine computer.

Key facts about the 2000 Ford Taurus fuel pump fuse:

  1. Location: The fuel pump fuse is located in the Power Distribution Box under the hood, on the driver's side near the battery.
  2. Fuse Rating: It is a 20-amp fuse, typically labeled as "Fuel Pump" or "FP" in the fuse box diagram.
  3. Relay Location: The fuel pump relay is also in the same under-hood fuse box, often labeled as "Fuel Pump Relay" or "FP Relay."

Step-by-Step: How to Locate and Check the Fuel Pump Fuse

Before you spend money on a new fuel pump, always check the fuse first. Here's a simple, step-by-step guide:

  1. Open the Hood: Locate the fuse box on the driver's side. It's a black plastic box with a removable cover.
  2. Remove the Cover: Press the tabs on the sides of the cover and lift it off.
  3. Find the Diagram: Look at the underside of the cover or the diagram chart inside the box. This will show you where the fuel pump fuse and relay are located.
  4. Identify the Fuse: The fuel pump fuse is usually a 20-amp fuse (often yellow or clear). In many diagrams, it's labeled "FUEL PUMP" or "F/P."
  5. Check the Fuse: Visually inspect the metal strip inside the fuse. If it's broken or melted, the fuse is blown. You can also use a test light or multimeter to check for continuity.
  6. Replace if Necessary: If the fuse is blown, replace it with a new 20-amp fuse of the same type. Never use a higher amperage fuse, as this can damage the wiring or cause a fire.

Common signs of a blown fuel pump fuse include:

  • The engine cranks but won't start.
  • No sound from the fuel pump when you turn the key to the "ON" position (you should hear a brief whirring sound from the rear of the car).
  • The car stalls while driving and won't restart.

What If the Fuse Blows Again?

If you replace the fuel pump fuse and it blows again immediately or shortly after, this indicates a deeper issue. The most common causes include:

  1. A Failing Fuel Pump: A worn-out fuel pump can draw excessive current, causing the fuse to blow repeatedly. This is the most common reason for repeated fuse failures.
  2. Short Circuit in the Wiring: Damaged or corroded wiring between the fuse box and the fuel pump can cause a short circuit.
  3. Faulty Fuel Pump Relay: A stuck or malfunctioning relay can cause the pump to run continuously or draw too much power.
  4. Clogged Fuel Filter: A severely clogged fuel filter can make the pump work harder, increasing current draw.

Pro Tip: If you've replaced the fuse and it still blows, do not keep replacing it without diagnosing the root cause. This can damage the fuel pump driver module or the vehicle's computer.

Testing the Fuel Pump Relay

The fuel pump relay is another common failure point. Here's how to test it:

  1. Locate the Relay: In the same under-hood fuse box, find the relay labeled "Fuel Pump Relay" or "FP Relay."
  2. Swap the Relay: A simple test is to swap the fuel pump relay with a similar relay in the fuse box (like the horn relay or the AC relay). If the fuel pump starts working, the original relay is faulty.
  3. Listen for Clicking: With the key in the "ON" position, you should hear a click from the relay box. If you don't hear it, the relay might be dead.
  4. Use a Multimeter: If you have a multimeter, you can test the relay's resistance and continuity according to the manufacturer's specifications.

Fuel Pump Fuse Box Diagram for 2000 Ford Taurus

For your convenience, here are the key details from the 2000 Ford Taurus fuse box diagram:

Engine Compartment Fuse Box (Power Distribution Box):

  • Fuse 5 (20A): Fuel Pump (also listed as "FUEL PUMP" in some diagrams)
  • Relay (specific position may vary): Fuel Pump Relay (often labeled "FP RELAY")

Note: The fuse box diagram may vary slightly depending on the trim level (LX, SE, SHO) or if you have a wagon versus a sedan. Always refer to the diagram on the underside of your fuse box cover for the most accurate information.

Troubleshooting the Fuel System: A Step-by-Step Approach

If your car won't start, follow this logical troubleshooting sequence:

  1. Check the Fuel Pump Fuse: As discussed, this is the easiest and cheapest check.
  2. Check the Fuel Pump Relay: Perform the relay swap test.
  3. Listen for the Pump: Turn the key to the "ON" position (without starting the engine). You should hear a whirring sound from the fuel tank area (rear of the car) for 2-3 seconds. If you don't hear it, the pump may not be getting power.
  4. Check for Power at the Pump: Use a multimeter to check for 12 volts at the fuel pump connector (located under the rear seat or under the car near the fuel tank).
  5. Check the Fuel Pressure: Using a fuel pressure gauge, check the pressure at the fuel rail. For a 2000 Ford Taurus, it should be around 30-45 PSI (depending on the engine).
  6. Inspect Wiring: Look for damaged, corroded, or pinched wires leading to the fuel pump.

Why the Fuel Pump Fuse Blows: Common Causes and Solutions

Understanding why the fuse blows can help you fix the problem permanently. Here are the most common causes:

1. Worn-Out Fuel Pump (Most Common)

  • Cause: Over time, the internal bearings and brushes of the fuel pump wear out, causing it to draw more current than normal.
  • Solution: Replace the fuel pump.

2. Debris in the Fuel Tank

  • Cause: Rust, dirt, or debris can clog the pump's inlet screen, forcing it to work harder.
  • Solution: Clean the fuel tank and replace the fuel pump.

3. Faulty Fuel Pump Relay

  • Cause: A stuck relay can keep the pump running continuously, even when the engine is off, which can overheat the pump and blow the fuse.
  • Solution: Replace the relay.

4. Short Circuit in Wiring

  • Cause: Wires rubbing against the chassis or corroded connectors can cause a direct short.
  • Solution: Inspect and repair the wiring harness.

When to Replace the Fuel Pump Instead of Just the Fuse

If you've checked the fuse, relay, and wiring, and the problem persists, the fuel pump itself is likely failing. Here are the signs that it's time for a replacement:

  • Engine Sputters at High Speeds: The pump can't maintain enough fuel pressure.
  • Loss of Power Under Load: The car struggles to accelerate, especially uphill.
  • Hard Starting: The engine takes longer to start than usual.
  • Whining Noise from the Fuel Tank: A loud whining sound from the rear of the car indicates a failing pump.
  • Check Engine Light: The OBD-II code might indicate a lean fuel mixture or low fuel pressure.
