Replacing Fuel Pump In 2001 Mercury Sable: Step-By-Step Guide

If you're looking to change the fuel pump in your 2001 Mercury Sable, you'll first need to locate the fuel pump module. This can be found in the gas tank. It is not a DIY repair job and will require some expertise. You'll need to remove the fuel tank by hoisting the car up, disconnecting the connection for the pump, and unhooking the lines to the tank. It's important to wear safety glasses during this process as the fuel lines are under pressure. Once the tank is lowered, you can remove the lock ring and pull up the pump assembly.

The fuel pump is in the gas tank

To replace the fuel pump in a 2001 Mercury Sable, you will need to remove the fuel tank. This is not a DIY repair job.

First, hoist the car and disconnect the connection for the pump. Then, unhook the fuel lines from the tank. Be sure to wear safety glasses, as the fuel lines are pressurised. Next, remove the filler neck and vent hoses from the tank. Now, support the tank and remove the straps, bending them out of the way as you start to lower the tank. Always keep an eye out for connections you may have forgotten.

With the tank on the ground, remove the lock ring and pull up the pump assembly. The fuel pump then turns out. Some pumps can be rebuilt and are cheaper; instructions on how to do this come with the replacement pump.

Yes, to replace the fuel pump on a 2001 Mercury Sable, you will need to remove the fuel tank. Here is a step-by-step guide to help you through the process:

Step 1: Safety First

Before you begin, it is important to take some safety precautions. Make sure you are working in a well-ventilated area and avoid smoking or carrying any lighted tobacco or open flames near the vehicle. Highly flammable mixtures are always present in the fuel system, and any ignition source can result in a dangerous situation. Ensure that you disconnect the battery ground cable and relieve the system pressure before proceeding.

Step 2: Prepare the Vehicle

Drain the fuel tank and remove the screws. Raise the vehicle and remove the fuel tank filler pipe from the fuel tank.

Step 3: Disconnect Components

Locate and disconnect the fuel pump connector, which is usually above the No.4 crossmember. Then, disconnect the fuel lines and the vapor tube from the tee on the right side of the vehicle. Also, disconnect the vapor tube from the canister tube.

Step 4: Support the Fuel Tank

Position a safety support under the fuel tank to hold it securely in place.

Step 5: Remove the Fuel Tank Support Straps

Remove the nuts and carefully swing the fuel tank support straps away from the fuel tank.

Step 6: Lower the Fuel Tank

Once the straps are removed, carefully lower the fuel tank. At this point, you will have access to the fuel pump for replacement.

Step 7: Reinstall the New Fuel Pump

After installing the new fuel pump, follow these steps in reverse to reassemble the components and refuel the tank.

Please note that removing and replacing the fuel tank can be a complex and challenging task. If you feel uncomfortable or unsure about any part of the process, it is recommended to seek the assistance of a qualified mechanic or automotive professional.

The fuel pump is controlled by the Fuel Pump Driver Module

The 2001 Mercury Sable's fuel pump is controlled by the Fuel Pump Driver Module (FPDM). The FPDM controls the speed of the fuel pump to maintain constant pressure.

The FPDM is located in a small metal box behind the radiator, along with the PCM, fuel pump, and fan relay. It is powered by a fuse—specifically, fuse 225 2amp on the left side of the dash, which then powers the inertia switch and the fuel pump module.

Some people have reported that their 2001 Mercury Sable does not have a separate FPDM, and that the fuel pump is controlled only by a fuse, relay, and the computer, which engages the relay to operate the pump.

The Fuel Pump Driver Module is behind the passenger backrest

To access the Fuel Pump Driver Module (FPDM) on a 2001 Mercury Sable, you will need to move the passenger-side backrest. The FPDM is located behind it.

First, remove the four bolts holding the back of the seat in place. Then, on the passenger side, you will notice a black piece of trim. This can be slid off, as it is held in place by two plastic clips. Once removed, you will see two 10mm nuts holding the FPDM in place. To fully remove the FPDM, you will need to pull the trunk liner over slightly.

The FPDM controls the speed of the fuel pump to maintain constant pressure.

You can buy a new fuel pump online

Some fuel pumps are sold as part of a fuel pump module assembly, which includes other components such as a sender assembly, strainer, and lock ring. These additional parts may be useful if you need to replace any other components in your fuel system.

Before purchasing a fuel pump online, be sure to verify that the fuel pump is compatible with your specific vehicle by checking the product description and compatibility information. It is also a good idea to read reviews from other customers to get an idea of the quality and performance of the fuel pump.

In addition to purchasing a new fuel pump, you may also need to buy any necessary tools or equipment to install the fuel pump, such as a jack to lift your car.
