If your Lincoln Town Car fuel pump is not working, you can reset it by locating the reset button on the hinge. If the button is pushed down, you may have a pump failure. In this case, you can use a small screwdriver to push the button out and reset the switch. Alternatively, you can try to reset the Inertia Fuel Shutoff (IFS) switch, which is located in the luggage compartment on the outboard side of the LH hinge support. This switch is used to shut the fuel pump off in the event of a collision. If your fuel pump has failed, you can replace it yourself by first emptying your fuel tank to the minimum level and then unplugging any connections going to the fuel pump.

What You'll Learn
Resetting the fuel pump using the reset button
Resetting the fuel pump on a Lincoln Town Car using the reset button is a straightforward process. The first step is to locate the Inertia Fuel Shutoff (IFS) switch, which is usually found in the luggage compartment on the outboard side of the left hinge support. This switch is designed to shut off the fuel pump in the event of a collision, preventing potential fires or other hazards.
Once you've located the IFS switch, inspect the button on top of it. If it is pushed down, this could indicate a pump failure. To reset the fuel pump, simply press the button. If it is resistant and does not move, you may need to use a small screwdriver to gently push it out.
After resetting the switch, you can try to restart the engine. In some cases, the engine may need to be primed by turning the key to the "on" position a few times before cranking it. This process should get your Lincoln Town Car's fuel pump working again.
It is important to note that the fuel pump may not be the only issue preventing your car from starting. There could be other underlying problems, such as a faulty fuel filter or electrical issues. If resetting the fuel pump does not resolve the problem, it is recommended to consult a professional mechanic for further diagnosis.

Resetting the fuel pump using the inertia switch
The inertia switch is designed to shut off the fuel pump in the event of a collision. When a sharp impact occurs, the ball breaks loose from the magnet, rolls up a conical ramp, and strikes a target plate. This action opens the electrical contacts of the switch, disrupting power to the electric fuel pump. The engine will stop running within a few seconds of the fuel pump losing power.
The inertia switch must be manually reset before the engine can be restarted. In the reset position, the button can be pressed an additional 1.59 mm (0.0625 inches) against a spring. This is a normal condition.
To reset the fuel pump using the inertia switch, locate the switch in the luggage compartment. Check if the button on the switch is pushed down; if it is, this may indicate a pump failure. Use a small screwdriver to access the side of the switch and push the button out. Reset the switch by pushing it in or out.

Replacing the fuel pump in a Lincoln Town Car
The fuel pump in a Lincoln Town Car can be challenging to replace, and the process may vary depending on the model year of the vehicle. Here is a step-by-step guide on how to replace the fuel pump:
Step 1: Prepare the Vehicle
Start by emptying your fuel tank as much as possible. If you have a lift, great; if not, jack up the rear of your Lincoln and put the air suspension switch in the OFF position before safely blocking up the car. You will need enough space to slide under the car from the rear and access the fuel pump.
Step 2: Accessing the Fuel Pump
To access the fuel pump, you may need to lower the tank. This can be done by dropping the first two hangers on your exhaust system and pulling it to the side. Alternatively, some models may have a removable panel in the forward vertical panel of the tank that can be carefully twisted out.
Step 3: Disconnecting the Old Fuel Pump
Once you have access to the fuel pump, unplug any connections and disconnect the wires. You may need to cut the wires on the old pump, but be careful as this will void the warranty on the new pump assembly.
Step 4: Removing the Old Fuel Pump
Unbolt the old fuel pump and remove it from the tank. You may need to loosen the straps holding the tank and let it drop down, but be careful as the tank is not heavy if emptied properly.
Step 5: Installing the New Fuel Pump
Slide in the new fuel pump slowly, ensuring it is properly aligned. Bolt up the new pump with a new gasket and tighten the straps. Plug in the connections and add gasoline.
Step 6: Testing the New Fuel Pump
Prime the engine by turning the key to the "on" position a few times. You should hear the new pump buzzing each time you turn the key. Now try to crank the engine.
Additional Notes:
- It is recommended to change the fuel inline filter before refilling the gas tank. Be careful with the plastic clips that hold the gas filter in place, as they can be fragile.
- Some Lincoln Town Car models may not require dropping the tank to replace the fuel pump. However, this may involve cutting wires and voiding warranties, so proceed with caution.
- Always refer to your owner's manual or seek professional assistance if you are unsure about any steps in the replacement process.

Step-by-step guide to replacing the fuel pump
First, empty your fuel tank as much as possible. If you have a lift, great. If not, jack up the rear of your Lincoln, but before you do, go into your trunk and put the air suspension switch in the OFF position. Block up your car safely and at a height that allows you to slide on your back from the rear of the car and look up to see your fuel pump.
Next, unplug any connections you see going to the fuel pump. You will need as much space as possible to unbolt the pump. You may have to loosen the straps holding the tank and let it drop down. Pull out the old pump, slide in the new pump slowly, and bolt the pump up with a new gasket. Tighten the straps, plug in the connections, and add gas. Prime the engine by turning the key to the 'on' position a few times. You should hear the pump buzzing each time you turn the key. Now crank it.
It is also a good time to change your fuel inline filter before you refill the tank with gas. Be careful with the plastic clips that hold the gas filter in place, as they tend to be fragile.
Please note that some sources suggest that you do not need to drop the tank to replace the fuel pump in a Lincoln Town Car. However, other sources suggest that the tank needs to be dropped twice: once to replace the pump and a second time to test the fuel gauge.
