1997 Fuel Pump Relay: How to Find, Test, and Replace It on Your Ford Escort

The 1997 Ford Escort fuel pump relay is located in the engine compartment, near the left front headlight area, attached to the fuse box or the inner fender. If your Escort cranks but won't start, the fuel pump relay is one of the first things to check. This guide walks you through exactly where to find it, how to test it, and what to do if it fails.

Where Is the Fuel Pump Relay on a 1997 Ford Escort?

The fuel pump relay on a 1997 Ford Escort is typically located in the engine compartment by the left front headlight area . It is mounted near the fuse box or the battery . Some sources also indicate it is underneath the intake housing attached to the base of the right strut tower . The exact position can vary slightly depending on your specific model and trim level, so checking your owner's manual or the fuse box diagram is helpful.

The relay is a small, rectangular component that is usually easy to spot once you know where to look. It is responsible for controlling the power supply to the fuel pump, turning it on when the engine is running and off when the engine is stopped . If the relay fails, the fuel pump will not receive power, and the engine will not start.

How to Locate the Fuel Pump Relay Step by Step

If you are ready to find the relay yourself, follow these simple steps:

1. Open the hood and secure it properly.
2. Look for the fuse box in the engine compartment. It is usually a black plastic box located near the battery or the firewall on the driver's side .
3. Check the fuse box diagram on the underside of the fuse box cover. The diagram will show which relay is for the fuel pump. It is often labeled but may use a symbol or abbreviation.
4. Look near the left front headlight area. Many 1997 Ford Escorts have the fuel pump relay mounted on the inner fender or near the fuse box in that area .
5. If you do not see it there, check underneath the intake housing attached to the base of the right strut tower . This is another common location for this model year.

Once you have located the relay, you can visually inspect it for any signs of damage, such as corrosion or burnt contacts.

Common Symptoms of a Bad Fuel Pump Relay

A failing fuel pump relay can cause several problems. The most common symptoms include:

1. Engine cranks but does not start: This is the most obvious sign. You can hear the starter motor turning the engine, but the engine never fires up because the fuel pump is not getting power .
2. Intermittent starting issues: The car may start sometimes and not others. This happens when the relay works intermittently due to worn internal contacts.
3. Engine stalls while driving: If the relay fails while you are driving, the engine will suddenly lose power and stall. This can be dangerous, especially in traffic.
4. No fuel pump priming sound: When you turn the ignition key to the "ON" position (without starting the engine), you should hear a brief humming sound from the rear of the car for about 2 seconds. If you hear nothing, the fuel pump relay or the pump itself may be faulty .

How to Test the Fuel Pump Relay

Testing the fuel pump relay is a straightforward process that you can do with basic tools. Here is how:

Step 1: Remove the Relay
Carefully pull the relay out of its socket. Be gentle to avoid breaking the locking tabs on the relay .

Step 2: Identify the Terminals
Most fuel pump relays have a diagram on the side showing the terminals. The relay typically has four terminals: two for the control circuit (the coil) and two for the power circuit (the switch). The two thin wires are usually the control circuit, and the two thicker wires are for the power circuit .

Step 3: Test the Coil
Use an ohmmeter (multimeter set to resistance) to check the resistance across the two control circuit terminals. A good relay will show a specific resistance value, usually between 50 and 120 ohms. If the meter shows "OL" (open line) or zero resistance, the relay coil is bad .

Step 4: Test the Switch
Connect a jumper wire from the battery positive terminal to one control circuit terminal. Connect another jumper wire from the remaining control circuit terminal to a good ground on the vehicle. When you do this, you should hear a clicking sound from the relay. This means the coil is working. Then, use the ohmmeter to check for continuity between the two power circuit terminals. If the relay is working, the circuit should be closed (near zero resistance) when the coil is energized .

What to Do If the Relay Is Bad

If you have confirmed that the fuel pump relay is bad, you need to replace it. This is a simple DIY job that usually takes less than 10 minutes. Simply pull the old relay out and plug in a new one of the same type. Make sure the replacement relay matches the original in terms of pin configuration and amperage rating.

Other Causes of a No-Start Condition

Before replacing the fuel pump relay, consider other possible causes. The 1997 Ford Escort has a fuel pump shut-off switch (inertia switch) that can trip in a collision or after hitting a large pothole. This switch is located in the trunk on the passenger side, behind the trunk liner . If the switch is tripped, pressing the reset button will restore power to the fuel pump. Also, check the fuel pump fuse in the fuse box, as a blown fuse can cause the same symptoms.

How to Access the Fuel Pump Itself

If the relay and fuse are good, the problem may be with the fuel pump itself. The fuel pump on a 1997 Ford Escort is located inside the fuel tank . You can access it without dropping the fuel tank by removing the rear seat cushion and lifting the metal access panel on the floor pan . Underneath this panel, you will find the top of the fuel tank and the fuel pump module. This is a more involved repair, but it is still manageable for a DIY mechanic with basic tools.

Why the Fuel Pump Relay Is Important

The fuel pump relay is a small but critical component. It prevents the fuel pump from running continuously when the engine is off, which would drain the battery and could cause a fire hazard. It also ensures that the fuel pump runs only when the engine is running or when the ignition is in the "start" position. Without a properly functioning relay, your fuel system may not work at all.

Where to Buy a Replacement Fuel Pump
