1994 Ford Taurus Fuel Pump Relay Location: A Complete Guide to Finding and Fixing It

The bottom line: On a 1994 Ford Taurus, the fuel pump relay is not a standalone relay you can replace individually. It is built inside the Constant Control Relay Module (CCRM) or the Integrated Control Relay Module, depending on your engine size. The module is located in a metal box above the radiator, under the plastic trim panel that sits across the top of the radiator support. If you have a 3.8L V6 engine, the relay is inside the Integrated Control Relay Module . If you have a 3.0L V6 engine, the relay is inside the Constant Control Relay Module (CCRM) . In both cases, the entire module must be replaced if the fuel pump relay fails — you cannot simply swap out a single relay.

Where to Find the Fuel Pump Relay on a 1994 Ford Taurus

1. The Module Location

The fuel pump relay on a 1994 Ford Taurus lives inside a relay module that sits on top of the radiator fan shroud, centered in the engine bay. To access it, you need to remove the plastic cover that spans the top of the radiator. This cover usually has labels for the belt routing diagram, engine size, and other underhood information . Once you remove that plastic panel, you will see a metal box with a large wiring harness connector attached to it. That box is the relay module.

For 3.8L V6 models (1993-1995), this module is called the Integrated Control Relay Module . For 3.0L V6 models (1993-1995), it is called the Constant Control Relay Module (CCRM) . The function is the same — it houses multiple relays, including the fuel pump relay, the PCM power relay, and the cooling fan relay .

2. Why You Cannot Replace Just the Relay

This is one of Ford's less popular designs. The fuel pump relay is soldered into the module as a sealed unit. You cannot open the module and swap out a $20 relay. If the fuel pump relay fails, you must replace the entire module, which is considerably more expensive — some owners report dealer prices around $160 for the module . The module is a common failure point, and when it goes bad, it often affects multiple systems at once.

3. Signs That the Fuel Pump Relay Module Is Failing

If your cooling fan comes on as soon as you turn the ignition key to the ON position, even when the engine is cold, that is a classic sign that the Constant Control Relay Module has failed . The fuel pump relay and the cooling fan relay are both inside the same module, so a failure in one circuit often means the entire module is compromised.

Other common symptoms include:

  • The engine cranks but will not start
  • No humming sound from the fuel pump when you turn the key to the ON position
  • Intermittent stalling followed by the car restarting after a few minutes
  • The engine starts fine one day but refuses to start the next day

When the fuel pump relay fails, the pump does not receive power, which means no fuel pressure reaches the engine. The starter may turn fine, but the engine will not fire .

How to Diagnose the Fuel Pump Circuit Before Replacing the Module

Before you spend money on a new CCRM or Integrated Control Relay Module, it pays to do some basic electrical checks. A faulty fuel pump, a blown fuse, a tripped inertia switch, or a bad ground can all mimic the symptoms of a bad relay module.

Check the Fuel Pump Fuse

The fuel pump fuse is located in the engine compartment fuse box. On a 1994 Taurus with a 3.0L engine, look for a 20-amp fuse in position #10 . Pull the fuse and inspect it. If the metal strip inside is broken, replace it. If the fuse is good, use a 12-volt test light or a digital multimeter to confirm that you have voltage on both sides of the fuse. If you have power on one side but not the other, the fuse is blown.

Check the Inertia Switch

The fuel pump inertia switch is a safety device that shuts off the fuel pump in the event of a collision. On a 1994 Ford Taurus sedan, it is located in the trunk behind the trim lining on the passenger-side (right side) wheel well. On a wagon, it is in the cargo area, behind the passenger-side trim panel just behind the wheel well .

The inertia switch has a button on top. If it has been triggered, the button will be popped up. Press it down firmly to reset it. This is a common issue that many owners overlook. If the switch is not tripped, you can still use it as a diagnostic point.

To check for power at the inertia switch, disconnect the electrical connector from the switch. Have a helper turn the key to the ON position and crank the engine. While they crank, use a test light or multimeter to check for 12 volts on the power-in wire (the dark green with yellow stripe wire). If you see voltage here for 1-2 seconds while cranking, the fuel pump relay and fuse are working . If you have no voltage, the problem is upstream — either the relay, the fuse, or the wiring.

Check the Ground

A bad ground can cause intermittent fuel pump failure. On the 1994 Taurus, the chassis ground for the fuel pump circuit is located near the battery and inner fender area . Clean the ground connection with a wire brush and ensure it is tight. Corrosion at the ground point is a known issue on these vehicles.

Check the PCM Power Relay

The fuel pump relay depends on the PCM power relay to function. If the PCM power relay has failed, the fuel pump relay will not be triggered. On the 3.0L models, both relays are inside the same CCRM module . On 3.8L models, the PCM power relay is also inside the Integrated Control Relay Module . In both cases, if the PCM power relay fails, the engine will not start at all.

What Happens When the Module Fails

When the Constant Control Relay Module or Integrated Control Relay Module fails, the fuel pump relay inside stops working. This means the fuel pump does not receive power when the ignition is turned on. You will not hear the normal 2-second prime sound from the fuel pump. Without fuel pressure, the injectors cannot spray fuel, and the engine will crank but not start .

The module failure can be intermittent. Some owners report that the car will start fine for a week, then suddenly refuse to start, then start again 10 minutes later . This is a strong indicator of a failing relay inside the module rather than a completely dead fuel pump.

How to Replace the Module

Replacing the module is straightforward. Here are the steps:

  1. Disconnect the battery negative cable to avoid any electrical shorts.
  2. Remove the plastic trim panel that sits across the top of the radiator. It may be held in place by clips or push pins.
  3. Locate the metal box mounted on top of the radiator fan shroud. This is the relay module.
  4. Disconnect the large wiring harness connector from the module. There is usually a locking tab or clip that must be pressed to release the connector.
  5. Remove the mounting screws or bolts that hold the module in place.
  6. Install the new module and secure it with the mounting hardware.
  7. Reconnect the wiring harness connector until it clicks into place.
  8. Reinstall the plastic trim panel and reconnect the battery.
  9. Test the system by turning the key to the ON position. You should hear the fuel pump prime for about 2 seconds.

A Note on Engine Variations

The 1994 Ford Taurus came with two main engine options: the 3.0L V6 and the 3.8L V6. The location of the fuel pump relay is the same for both — inside the module on top of the radiator — but the module itself has different part numbers. For the 3.0L, the module is specifically the Constant Control Relay Module (CCRM) . For the 3.8L, it is the Integrated Control Relay Module . Make sure you order the correct module for your engine size.

The genuine Ford part number for the relay assembly is E4LZ9345A, which fits 1990-1995 Ford Taurus models with 3.0L, 3.2L, and 3.8L engines . However, this is the relay itself, not the complete module. Since the relay is not serviceable separately, you need to purchase the entire module assembly.

Other Common Causes of No Fuel Pump Operation

Before you conclude that the relay module is bad, check these items:

  • Fuel pump fuse: A blown fuse is the easiest fix. Check the 20-amp fuse in the engine compartment fuse box .
  • Inertia switch: The switch can trip from a hard bump or pothole, not just a collision. Reset it by pressing the button.
  • Fuel pump itself: The pump is mounted inside the fuel tank. On the 1994 Taurus, you must drop the tank to access it . If the pump has failed, you will hear no sound from the rear of the car when the key is turned on.
  • Wiring issues: Corroded connectors, broken wires, or bad grounds can interrupt power to the pump. Check the ground connection near the battery .
  • PCM failure: The Powertrain Control Module sends the signal to the fuel pump relay. If the PCM is dead, the relay will not close.

Why You Should Not Ignore This Problem

Driving with a failing fuel pump relay is risky. If the relay fails while you are driving, the engine will stall instantly, leaving you without power steering or brake assist. This can be dangerous, especially at highway speeds. Additionally, an intermittent fuel pump can cause the engine to run lean, which may overheat and damage the catalytic converter or the engine itself. If you suspect the relay module is failing, replace it as soon as possible.
