2002 Lincoln Town Car Fuel Pump Location: Where It Is and How to Replace It
The bottom line: The fuel pump on a 2002 Lincoln Town Car is located inside the fuel tank, which is mounted vertically behind the rear seat. To access it, you must drop the entire fuel tank from underneath the vehicle — there is no access hatch from inside the cabin or trunk. The fuel pump relay is located in the engine compartment power distribution box (relay #1), and the inertia fuel shut-off switch is in the trunk on the left side near the hinge. Replacing the pump is a moderately difficult job that requires draining the tank, disconnecting fuel lines, and carefully lowering the tank, but with the right tools and safety precautions, it can be done at home.
Where Exactly Is the Fuel Pump Located?
The fuel pump on your 2002 Lincoln Town Car is not accessible from inside the car. Unlike many modern vehicles that have a service hatch under the rear seat, the 1998-2002 Town Car requires you to drop the fuel tank to get to the pump assembly . The tank is mounted vertically behind the rear wheels, and the fuel pump is installed through an opening near the top of the tank .
The fuel pump assembly includes the pump motor, the fuel level sending unit, the strainer, and the housing. It is all one unit that sits inside the tank . When you remove the cap from the top of the tank, you will see the pump attached to the sending unit, submerged in the fuel .
Where Are the Fuel Pump Relay and Inertia Switch?
The fuel pump relay is not in the trunk or under the dash. It is located in the power distribution box (the main fuse box) in the engine compartment. It is relay #1 . This relay controls power to the fuel pump. If your car cranks but does not start, checking this relay is a good first step.
The inertia fuel shut-off switch is a safety device that cuts power to the fuel pump in the event of a collision. On the 2002 Town Car, this switch is located in the trunk, on the left side near the trunk hinge . If you hit a large pothole or have a minor impact, this switch can trip, preventing the car from starting. Before assuming your fuel pump is bad, always check and reset this switch by pressing the button on top.
Signs You Need to Replace the Fuel Pump
Before you go through the trouble of dropping the tank, make sure the pump is actually the problem. Common symptoms of a failing fuel pump on a 2002 Lincoln Town Car include:
1. Engine hard to start, especially when cold. A failing check valve in the pump causes the fuel system pressure to drop, making it harder to get fuel to the engine on the first crank .
2. Loss of power during acceleration. If the pump is worn out, it cannot deliver enough fuel under load, causing the car to feel sluggish or hesitate when you step on the gas .
3. Whining noise from the rear of the car. A healthy fuel pump makes a low hum when you turn the key to the "on" position. If you hear a loud whining or screeching sound from the rear of the vehicle, the pump bearings are likely failing.
4. The engine cranks but will not start. If the pump is completely dead, you will not hear the fuel pump prime when you turn the key. Check the relay and inertia switch first, but if those are fine, the pump itself may be the culprit.
5. Inaccurate fuel gauge reading. The fuel level sending unit is attached to the pump assembly. If your gauge shows empty when the tank is full, or jumps around erratically, you may need to replace the entire assembly .
Step-by-Step Guide to Replacing the Fuel Pump
Replacing the fuel pump on a 2002 Lincoln Town Car requires dropping the fuel tank. The job is rated as intermediate difficulty and requires basic mechanical tools . Here is the process in order.
Step 1: Safety First
Before you start, disconnect the negative battery terminal. This prevents electrical sparks that could ignite fuel fumes. Work in a well-ventilated area, have a fire extinguisher nearby, and wear safety glasses and gloves. Gasoline is highly flammable and can irritate your skin .
Step 2: Turn Off the Air Suspension
This is a critical step unique to the Lincoln Town Car. Open the trunk and locate the suspension switch on the left side. It is a plastic switch marked "On" and "Off." Turn it to the "Off" position. Do not jack up the vehicle with the suspension on, as this can tear the air bags and cause serious damage .
Step 3: Jack Up the Car and Drain the Fuel Tank
Jack up the rear of the car and place it securely on jack stands. Look for the drain plug on the bottom of the fuel tank. Place a container underneath to catch the fuel, then remove the plug to drain the tank. Draining the tank makes it much lighter and safer to handle .
Step 4: Support the Fuel Tank and Remove the Straps
Using a ratchet, unscrew the four bolts that hold the metal bands (straps) around the fuel tank. As you loosen these bolts, the tank will start to drop. Place a jack or a tall cinder block under the tank to support its weight as you lower it. The tank is oblong-shaped, so you will need to pivot it back and forth to help it come down .
Step 5: Disconnect the Fuel Lines
Once the tank is lowered enough to access the top, disconnect the fuel inlet line. This line connects to the top portion of the tank and is held in place by a hose clamp. Use a screwdriver to loosen the clamp, then slide the line off. You may also need to disconnect electrical connectors and any other lines running into the cap. Lay the tank flat on the ground .
Step 6: Remove the Old Fuel Pump Assembly
You may need a hammer and a screwdriver to loosen the large locking ring or cap on top of the tank. Pull the cap straight up and out. You might need to turn the assembly at an angle as you pull it out, since the fuel sending unit is attached to it. The fuel pump is visible once the cap is removed. The pump and sending unit are attached together, so you will remove the entire assembly .
Pro tip: Note the position of the o-ring. You will need to replace it with a new one when you reassemble the tank.
Step 7: Clean the Tank
Before installing the new pump, wash out the inside of the fuel tank to remove any sediment, rust, or debris that has accumulated over the years. You can use the excess fuel or water, but if you use water, make sure the tank is completely dry before reinstalling it .
Step 8: Install the New Fuel Pump Assembly
Place the new o-ring on the threaded part of the tank where the old one was. Install the new fuel pump assembly into the tank, making sure the float arm is positioned correctly. Seat the cap or locking ring firmly, and tighten it securely. Reconnect the electrical connectors and the fuel lines. Make sure the cap is tight and all lines are secured. The electrical lines and small hoses should snap into place .
Step 9: Reinstall the Fuel Tank
Lift the tank back into position using the jack. Put the metal bands back into place and snug the bolts so the tank is held securely. Reconnect the fuel inlet hose from the gas cap. Once everything is in place, tighten the bands fully .
Step 10: Replace the Fuel Filter
This is a critical step. The fuel filter on a 2002 Lincoln Town Car is located on the frame rail, running along the side of the driver's door. It is inexpensive and easy to replace. A clogged old filter will restrict fuel flow, forcing your new pump to work harder and causing it to fail prematurely . Always replace the fuel filter when you replace the pump.
Step 11: Reset the Inertia Switch and Start the Car
After working on the fuel system, the inertia cut-off switch may have been triggered. Locate it in the trunk (left side near the hinge) and press the reset button. If the car is off the jack, turn the suspension switch back to the "On" position. Now, turn the key to the "On" position for a few seconds (without cranking) to prime the fuel system. Repeat this two or three times, then try to start the engine. Check for fuel leaks around all connections .
Important Tips for a Successful Replacement
Replace the entire assembly, not just the pump motor. The labor involved in dropping the tank is significant. If you only replace the pump motor, the old sending unit or strainer could fail later, forcing you to do the job all over again. Always replace the complete fuel pump module assembly .
Use jack stands, not just a jack. The fuel tank is heavy, and working under the car is dangerous. Never rely on a single jack to support the vehicle.
Be careful with the fuel lines. The 2002 Town Car uses quick-disconnect fittings on some fuel lines. You may need a specialty tool to disconnect them without damaging the lines .
Check for recalls. There are no specific NHTSA recalls for fuel pump failure on the 1998-2002 Lincoln Town Car, but there were some technical service bulletins (TSBs) related to the fuel tank straps and a clunking noise. Check with your local dealer if you are concerned .
