1999 Lincoln Continental Fuel Pump Relay Location: A Complete Guide for Owners

The fuel pump relay on a 1999 Lincoln Continental is located in the engine compartment fuse box (also called the Power Distribution Box), near the battery on the driver's side. This is the first thing you need to know if your car is having trouble starting or if the engine cranks but won't fire up. The relay is clearly labeled as "FP" (Fuel Pump) on the fuse box cover, making it straightforward to find and check.

Understanding the Fuel Pump Relay

The fuel pump relay is an electrical switch that controls power to the fuel pump. When you turn the ignition key to the "ON" position, the relay activates and sends battery voltage to the fuel pump, allowing it to pressurize the fuel system. If this relay fails, the fuel pump won't receive power, and your engine won't start even if the pump itself is in good condition.

Step-by-Step: How to Locate the Fuel Pump Relay

Step 1: Open the hood of your 1999 Lincoln Continental. Make sure the engine is cool and the vehicle is parked on a level surface with the parking brake engaged.

Step 2: Find the Under Hood Fuse Box (Power Distribution Box). This black plastic box is located in the engine bay, very close to the battery on the driver's side of the vehicle. It's a rectangular box with a removable cover.

Step 3: Remove the cover of the fuse box. Most covers have clips or tabs that you press to release them. Set the cover aside in a safe place.

Step 4: Look for the label "FP" on the inside of the cover or directly on the fuse box. The fuel pump relay is typically marked with "FP" or "Fuel Pump" on the diagram printed on the cover. In the 1997 model, which shares a similar layout, the relay is also in this same location.

Step 5: Identify the relay itself. The fuel pump relay is a small, rectangular black or gray component that plugs into the fuse box. It is usually one of several relays in the box.

How to Test the Fuel Pump Relay

Before replacing the fuel pump, which is a more expensive and labor-intensive job, it's smart to test the relay first. Here's how:

1. Visual inspection: Pull the relay straight up out of its socket. Look for signs of corrosion, burnt plastic, or melted pins. If you see any damage, replace the relay.

2. Swap test: This is the easiest method. Find another relay in the same fuse box that has the same part number and amperage rating. Swap the fuel pump relay with that relay. If the other component (like the horn or cooling fan) stops working, but your fuel pump starts working, then the original relay was bad.

3. Listen for the relay: With the vehicle in a quiet area, turn the ignition key to the "ON" position (do not start the engine). You should hear a faint click from the engine bay fuse box area. This clicking sound means the relay is activating. If you don't hear it, the relay or its control circuit may be faulty.

Common Symptoms of a Bad Fuel Pump Relay

If your fuel pump relay is failing, you may notice one or more of these symptoms:

• Engine cranks but won't start: This is the most common symptom. The starter motor turns the engine over, but the fuel pump never primes, so no fuel reaches the injectors.
• No sound from the fuel pump: When you turn the key to "ON," you should hear a brief whirring sound from the rear of the car (near the fuel tank) for about 2-3 seconds. If you hear nothing, the relay or pump could be the issue.
• Intermittent starting problems: The car may start fine one day and refuse to start the next. This is a classic sign of a failing relay.
• Engine stalls while driving: If the relay fails while you're on the road, the fuel pump will lose power, and the engine will stall immediately.

What to Do If the Relay Checks Out Fine

If you've tested the fuel pump relay and it appears to be working correctly, the problem might be elsewhere in the fuel system. Here are other common causes of fuel delivery problems on a 1999 Lincoln Continental:

1. Faulty fuel pump: The fuel pump itself may have failed. On a 1999 Lincoln Continental, the electric fuel pump is located inside the fuel tank. This is a common failure point on older vehicles, especially if the fuel tank was frequently run low, which can cause the pump to overheat.

2. Blown fuel pump fuse: The fuse box under the hood also contains a fuse for the fuel pump. Check the fuse labeled for the fuel pump or fuel system. A blown fuse can be caused by a short circuit or a failing pump that draws too much current.

3. Clogged fuel filter: A severely clogged fuel filter can restrict fuel flow and mimic the symptoms of a bad pump. Replacing the fuel filter is a standard maintenance item that should be done regularly.

4. Inertia switch (fuel shut-off switch): The 1999 Lincoln Continental has an inertia switch that cuts power to the fuel pump in the event of a collision. On this model, the inertia switch is located to the left of the driver's seat, behind an access panel on the "B" pillar (the pillar between the front and rear doors). If this switch has been tripped, it will prevent the fuel pump from running. To reset it, simply press the button on top of the switch.

5. Wiring or connector issues: Corrosion or damage to the wiring harness that connects to the fuel pump or the relay can interrupt power. Check the connectors at the fuse box, the fuel tank, and along the frame for any signs of damage.

Additional Information About the 1999 Lincoln Continental Fuel System

For a 1999 Lincoln Continental, the fuel pump is an in-tank electric pump, meaning it is mounted inside the fuel tank. To access the pump for replacement, you typically need to remove the rear seat cushion or access it from the trunk. Some owners report that the fuel pump module is located in the trunk, behind the carpet on the passenger side, right behind the back seat. The fuel pump driver module (not the relay) is a separate component that some earlier models used, but the relay remains the primary control point for power delivery.

When replacing the fuel pump, it is highly recommended to use a factory-quality unit. Aftermarket pumps that do not meet OEM specifications can fail prematurely or cause drivability issues.
