2000 Ford Taurus Fuel Pump Relay Location: A Complete Guide to Finding, Testing, and Replacing It

The fuel pump relay on a 2000 Ford Taurus is located in the Power Distribution Box (PDB) under the hood, near the battery. It is relay #30 in that box. This is the most common and reliable location across all trim levels of the 2000 model year. If your Taurus is experiencing starting issues, stalling, or hesitation during acceleration, the fuel pump relay is one of the first components you should check before diving into more expensive repairs like replacing the fuel pump itself.

Understanding the Fuel Pump Relay and Its Role

The fuel pump relay is an electrically controlled switch that delivers power to the fuel pump. When you turn the ignition key to the "on" position, the Powertrain Control Module (PCM) sends a signal to the relay, which then closes the circuit and allows battery voltage to reach the fuel pump. This pump pressurizes the fuel system so the engine can start and run properly.

Without a working relay, the fuel pump won't receive power, and your engine won't get the fuel it needs. The relay is designed to prevent the fuel pump from running continuously when the engine is off, which protects both the battery and the fuel system from damage. It also ensures the pump operates only when the engine is running or during the initial startup sequence.

Exact Location of the Fuel Pump Relay

Under the Hood: The Power Distribution Box

For the 2000 Ford Taurus, the fuel pump relay is housed in the Power Distribution Box (PDB), which is a large, rectangular black plastic box located in the engine compartment. You will find this box near the battery, typically on the driver's side of the engine bay.

Here is how to access it:

  1. Open the hood and locate the Power Distribution Box. It is usually positioned close to the battery, with a removable lid.
  2. Remove the lid by pressing the tabs or clips on the sides. Be careful, as the PDB is "live" and contains electrical power even when the vehicle is off.
  3. Look for the relay diagram on the underside of the lid. This diagram shows the position and function of each relay and fuse inside the box.
  4. Find relay #30 on the diagram. This is the fuel pump relay for the 2000 Ford Taurus. In some cases, the relay may be labeled "FP" or "Fuel Pump" directly on the lid or on the relay itself.
  5. Pull the relay straight out using a firm, steady grip. You may need a small flathead screwdriver to gently pry it up if it is stuck.

Alternative Locations

While the under-hood PDB is the standard location, some owners have reported finding the fuel pump relay in other spots on certain 2000 Taurus models. These are less common but worth knowing about:

  • Inside the passenger compartment under the dashboard, near the kick panel or fuse panel. This is more typical of earlier 1996-1999 models, but some 2000 models may have it there.
  • Behind the engine coolant reservoir as part of the Constant Control Relay Module (CCRM). Some 2000 Taurus models with the 3.0L engine have the relay integrated into this module.

If you cannot find the relay in the PDB, check your owner's manual. The manual contains a diagram of the Power Distribution Box and all relay locations. You can also view the 2000 Ford Taurus owner's manual online at www.motorcraftservice.com by clicking on "Owner Guides" and navigating to page 137 for the PDB diagram.

Symptoms of a Faulty Fuel Pump Relay

A failing fuel pump relay can cause a range of problems that mimic other fuel system issues. Recognizing these symptoms early can save you time and money on unnecessary repairs. Here are the most common signs:

1. Engine cranks but does not start. This is the most obvious symptom. When you turn the key, the starter motor engages and the engine turns over, but it never fires up. This happens because the relay is not sending power to the fuel pump, so the fuel system has no pressure.

2. Intermittent stalling or hesitation. A failing relay may work sometimes and fail at other times. This can cause the engine to suddenly lose power while driving, especially during acceleration or under load. The engine may sputter and then die, only to restart later after the relay cools down.

3. No fuel pump priming sound. When you turn the ignition key to the "on" position (without starting the engine), you should hear a faint whirring or humming sound from the fuel tank area for about two seconds. This is the fuel pump priming the system. If you hear no sound, the relay may be the problem.

4. Unusual noises from the fuel tank. A blown relay can cause the fuel pump to attempt to engage but fail, producing a faint whining or humming sound that is more noticeable during startup. If the pump fails to engage entirely, the absence of this sound is also a sign of relay trouble.

How to Test the Fuel Pump Relay

Before replacing the relay, you should test it to confirm it is the source of the problem. Here are two simple methods:

Method 1: Swap with a Known Good Relay

This is the easiest and fastest way to test the relay. The Power Distribution Box contains several relays that are identical to the fuel pump relay. For example, the horn relay, wiper relay, or A/C clutch relay are often the same part.

  1. Locate the fuel pump relay (relay #30) and pull it out.
  2. Find a similar relay in the same box, such as the horn relay.
  3. Swap the two relays. Plug the fuel pump relay into the horn relay slot, and plug the horn relay into the fuel pump relay slot.
  4. Try to start the engine. If the engine starts, the original fuel pump relay was faulty. If the horn stops working, the relay is good but the problem lies elsewhere.

Method 2: Use a Multimeter

If you have a multimeter, you can test the relay for continuity and voltage.

  1. Set your multimeter to the ohms (Ω) setting.
  2. Identify the relay terminals. A standard 30-amp SPST relay has four terminals: 30 (common), 87 (normally open), 85 (coil), and 86 (coil).
  3. Check for continuity between terminals 85 and 86. You should see a resistance reading, typically between 50 and 120 ohms. If you get infinite resistance (open circuit), the relay coil is bad.
  4. Apply 12 volts to terminals 85 and 86 using a battery or power source. You should hear a click, and continuity should appear between terminals 30 and 87. If not, the relay is faulty.

Other Causes of Fuel Pump Problems

If the fuel pump relay tests good, the problem may be elsewhere in the fuel system. Here are other components to check:

Fuel pump fuse. The fuel pump circuit has a fuse in the Power Distribution Box. Check the fuse for your specific model year, which is usually a 20-amp mini fuse. If the fuse is blown, replace it and check for a short circuit if it blows again.

Inertia fuel shut-off switch. The 2000 Ford Taurus has an inertia switch that cuts power to the fuel pump in the event of a collision. This switch is located in the trunk, usually on the right side behind the trim panel. If the switch is tripped, press the reset button to restore power to the fuel pump.

Fuel pump itself. If the relay, fuse, and inertia switch are all good, the fuel pump may be failing. The fuel pump is located inside the fuel tank. Symptoms of a bad pump include a whining noise from the tank, difficulty starting, and loss of power at high speeds. Testing fuel pressure requires a gauge connected to the test port on the fuel rail. For a 2000 Taurus, the fuel pressure should be 37 to 45 psi with the ignition on and the engine off.

Wiring and connectors. Corroded or loose connections at the fuel pump harness or the relay socket can cause intermittent power loss. Inspect the wiring for damage, and clean any corrosion from the connectors.

How to Replace the Fuel Pump Relay

Replacing the fuel pump relay on a 2000 Ford Taurus is a straightforward DIY job that takes less than 10 minutes. You do not need any special tools.

  1. Disconnect the negative battery terminal to prevent accidental shorts or electrical shocks.
  2. Locate the Power Distribution Box under the hood and remove the lid.
  3. Identify relay #30 using the diagram on the lid or your owner's manual.
  4. Pull the old relay straight out using a firm grip. If it is stuck, use a small flathead screwdriver to gently pry it up.
  5. Insert the new relay into the same slot. Make sure it is fully seated and clicks into place.
  6. Reconnect the battery terminal and test the system by turning the ignition on. You should hear the fuel pump prime for two seconds.
  7. Start the engine to confirm the repair is successful.

When purchasing a replacement relay, make sure it matches the original specifications. The fuel pump relay for a 2000 Ford Taurus is typically a 30-amp, four-pin SPST (single-pole, single-throw) relay. You can buy these at any auto parts store or online.

Preventing Future Relay Failures

Fuel pump relays can fail due to age, heat, vibration, and electrical surges. Here are some tips to extend the life of your relay:

  • Regularly inspect the relay and its connections for corrosion, rust, or damage. This is especially important on older vehicles like the 2000 Taurus.
  • Replace the relay proactively during routine maintenance, such as when you replace the fuel filter or spark plugs. A new relay costs only a few dollars and can prevent unexpected breakdowns.
  • Keep the Power Distribution Box clean and free of debris. Moisture and dirt can cause corrosion on the relay terminals.
  • Use a high-quality relay from a reputable brand. Cheap relays may not last as long or handle the electrical load correctly.

Why a Reliable Fuel Pump Matters

If you have tested the relay, fuse, and inertia switch, and the problem persists, the fuel pump itself may be the culprit. The fuel pump on a 2000 Ford Taurus is located inside the fuel tank, and replacing it requires dropping the tank or removing the rear seat to access the access panel. This is a more involved repair, but it is still manageable for a DIY mechanic with basic tools.

When it comes time to replace the fuel pump, choosing a high-quality part is critical. A cheap pump may fail quickly, leaving you stranded and costing you more in labor and downtime. You need a pump that delivers consistent performance and long-term reliability.
