1998 Ford Escort Fuel Pump Relay: Complete Location, Testing, and Replacement Guide

The bottom line: The 1998 Ford Escort fuel pump relay is not a standalone relay you can easily swap out. It is built into the Constant Control Relay Module (CCRM), a black box located under the air filter housing on the driver's side fender. If your Escort cranks but won't start, the CCRM module is one of the first things to check before replacing the fuel pump itself.

The fuel pump relay controls the power supply to your fuel pump. When you turn the key to the "ON" position, the relay should close and send power to the pump. The fuel pump only operates when the engine is cranking or running. It does not operate when the engine is not running, even with the ignition switch turned "ON" . If the relay fails, the pump will not get power, and your engine will not start.

Where Is the Fuel Pump Relay on a 1998 Ford Escort?

The exact location depends on the body style of your Escort. Here is what you need to know:

For all 1998 Ford Escort models (including the ZX2, sedan, and wagon): The fuel pump relay is located inside the CCRM module. This module is a 4x4 inch black box with a large wiring harness connected to it. It is mounted on the driver's side fender, just below the air intake housing and next to the strut tower .

For the 1998 Ford Escort ZX2 specifically: The CCRM is located under the air filter box. You will need to remove the air filter housing to access it. The CCRM controls not only the fuel pump relay but also relays for the A/C compressor, PCM power, and high and low-speed radiator fan relays .

Important distinction: If you have a 1998 Ford Escort built for the South African market, the fuel pump relay is listed as Relay 6 in the fuse box diagram located under the dashboard . However, for North American models, the CCRM is the correct location.

How the CCRM Works

The CCRM is a sealed module that contains multiple relays inside a single housing. On the 1998 Escort, it includes :

  1. Fuel pump relay – Controls power to the fuel pump
  2. A/C compressor relay – Controls the air conditioning clutch
  3. PCM power relay – Provides power to the Powertrain Control Module
  4. Radiator fan relays – Controls high and low-speed fan operation

This means if your CCRM fails, you may experience multiple issues at once, not just a fuel pump problem. The entire module must be replaced as a unit.

Where to Buy a Replacement CCRM

The CCRM is an expensive part at the dealer. A new genuine Ford CCRM can cost around $135 . If you are on a budget, a salvage yard is a good option. A used CCRM from a 1997 to 2002 Ford Escort will fit your 1998 model, and you can typically get one for about $20 .

Before Replacing the Fuel Pump Relay: Check These First

Before you spend money on a new CCRM or fuel pump, there are several other things to check. Many no-start issues on the 1998 Escort are caused by simpler problems.

1. Check the Fuel Pump Shut-Off Switch (Inertia Switch)

The 1998 Escort has a fuel pump shut-off switch that cuts power to the pump in the event of a collision. If you hit a pothole or got into a minor accident, this switch may have tripped.

Location of the inertia switch:

  • Coupe models: The switch is located on the right side of the trunk, behind the trunk liner
  • Sedan and wagon models: The switch is located in the driver's foot well, behind the kick panel

How to reset it: Push the button on top of the switch until you hear a click. Then try starting the car.

2. Check the Fuel Pump Fuse

The fuel pump is protected by a 30A fuse labeled "FUEL PUMP" in the power distribution box under the hood . A blown fuse will give you the same symptoms as a bad relay. Check the fuse visually and test it with a multimeter.

3. Check for Power at the Fuel Pump

If the fuse is good and the inertia switch is not tripped, the next step is to check if power is actually reaching the fuel pump. You can do this by listening for a buzzing sound from the rear of the car when you turn the key to "ON." If you hear nothing, the pump is either not getting power or the pump itself is dead.

How to Test the Fuel Pump Relay

If you want to test the relay itself, you can remove the CCRM and test the terminals. The relay pins are labeled on the module. Here is how to test the fuel pump relay specifically :

Step 1: Remove the CCRM module from the vehicle.

Step 2: Apply 12 volts across terminals "C" and "B" on the relay socket. While voltage is applied, measure the resistance between terminals "A" and "C". You should get a reading of less than 5 ohms.

Step 3: Remove the voltage. Measure resistance between terminals "A" and "C" again. You should get a reading of greater than 10,000 ohms.

Step 4: Apply 12 volts across terminals "E" and "F". Measure resistance between terminals "A" and "C". You should get less than 5 ohms.

Step 5: Remove the voltage. Measure again. You should get greater than 10,000 ohms.

If you do not get these readings, the relay is bad and the CCRM needs to be replaced.

Where Is the Fuel Pump Itself Located?

If the relay and fuse check out, the problem may be with the fuel pump itself. The fuel pump on a 1998 Ford Escort is located inside the fuel tank .

Accessing the fuel pump:

  1. Remove the bottom portion of the rear seat
  2. You will see a metal access panel on the floor pan
  3. Remove the panel to reveal the top of the fuel tank
  4. You will see a locking ring on top of the tank. Removing it gives you direct access to the fuel pump module

This is a more involved repair, but it is doable with basic tools. You do not need to drop the fuel tank on most models.

Common Symptoms of a Bad Fuel Pump Relay

If the fuel pump relay in your CCRM is failing, you will likely experience one or more of these symptoms:

  • Engine cranks but will not start – This is the most common symptom. The engine turns over but gets no fuel.
  • Engine starts intermittently – Sometimes it starts, sometimes it does not. This points to a relay that is failing intermittently.
  • Engine stalls while driving – If the relay cuts out while you are driving, the engine will die immediately.
  • No fuel pump noise – You should hear a brief buzzing sound from the rear of the car when you turn the key to "ON." If you do not hear it, the pump is not getting power.

Why the Fuel Pump Relay Is So Important

The fuel pump relay does more than just turn the pump on and off. It prevents the fuel pump from running continuously when the engine is off, which would drain the battery and could create a fire hazard. It also ensures that the pump only runs when the engine is running or when the ignition is in the "start" position . Without a properly functioning relay, your fuel system will not work at all.

Other Causes of a No-Start Condition

If the fuel pump relay and fuse are good, consider these other potential causes:

  • Clogged fuel filter – A severely clogged filter can make the pump work harder and may cause the fuse to blow
  • Bad fuel pump – If the pump itself has failed, no amount of relay work will help
  • Wiring issues – Damaged or frayed wires in the fuel pump circuit can cause intermittent problems
  • ECU problems – The Engine Control Unit controls the fuel pump relay. If the ECU is faulty, the relay may not get the signal to close

Diagnosing the Problem Step by Step

Here is a simple troubleshooting sequence:

  1. First, check the inertia switch – Reset it if needed
  2. Check the 30A fuel pump fuse – Replace if blown
  3. Listen for the fuel pump – Turn the key to "ON" and listen for a buzz from the rear
  4. Check the CCRM – If you have a known good CCRM from a salvage yard, swap it in to test
  5. Test for power at the pump – If the pump is getting power but does not run, the pump is bad
  6. Test the fuel pump itself – Access the pump through the rear seat access panel
