Replacing The Fuel Pump In Your 2001 Acura Cl

Replacing the fuel pump in a 2001 Acura CL is a fairly straightforward process, but it can be labour-intensive to gain access to the pump. The process involves disconnecting the battery, removing the rear seats, taking out the fuel pump assembly, and then reassembling the parts. The tools required for the job include a socket set and ratchet, a small pry bar or flat-head screwdriver, a Phillips screwdriver, and a lock ring wrench, large water pump pliers, or a drift punch and hammer.

Before beginning the process, it is important to note that the fuel pump is a crucial component in any modern fuel-injected vehicle, supplying the engine with adequate fuel for proper operation. While fuel pumps can go out without warning, they usually provide some signs of deterioration, such as a loud whine while the engine is running, hard starting issues, engine surging or loss of power, and poor fuel economy.

The first step is to disconnect the negative (black) battery cable to prevent any electrical shorts and potential fires. Next, the rear seats need to be removed to access the fuel pump access panel on the floorboard. This involves removing the plastic trim pieces covering the seat mounting bolts and then removing the bolts themselves. With the seats removed, the fuel pump can be accessed through a small flap in the carpet. In some cases, the carpet may need to be cut with a utility knife to fully reveal the pump cover.

The pump cover is usually secured with screws, which need to be removed using a Phillips screwdriver. After removing the cover, disconnect the electrical harness plug and fuel line from the fuel pump. The lock ring can then be removed using a lock ring wrench, water pump pliers, or a drift punch and hammer. With the lock ring removed, the fuel pump assembly can be lifted out of the tank, allowing any residual fuel to drain. It is important to tilt the pump to allow the fuel level sensor arm to clear the tank opening.

For reassembly, install the rubber sealing gasket onto the new fuel pump and carefully slide it into the fuel tank, being careful not to damage the fuel level sensor arm. Ensure that the pump is fully seated and positioned correctly to allow for the connection of the fuel line and electrical harness plug. Install the locking ring securely to prevent fuel leaks, and if necessary, transfer the old fuel line quick connect coupler to the new fuel pump nipple. Connect the fuel pump wiring harness plug and reinstall the fuel pump cover and screws. Finally, reinstall the rear seat and trim covers, and reconnect the battery.

Disconnect the battery

Disconnecting the battery is a crucial first step when replacing the fuel pump in your 2001 Acura CL. Here is a detailed, step-by-step guide on how to do it safely and effectively:

Step 1: Locate the Battery

Before you begin, put on safety gloves and goggles to protect your hands and eyes during the process. Open the hood of your Acura CL and locate the battery. It is usually hidden under a cover on the right front side of the engine bay. Simply pop up or remove the cover to access the battery.

Step 2: Disconnect the Negative Cable

You will see two cables connected to the battery terminals—a red positive cable and a black negative cable. Always start by disconnecting the negative cable first. Loosen the nut or bracket securing the negative cable to the battery terminal using a 10 mm socket, wrench, or even pliers. Once it is loose, carefully remove the cable from the terminal.

Step 3: Disconnect the Positive Cable

Now, move on to the positive cable. Again, loosen the nut or bracket securing the cable using the appropriate tool. After loosening it, carefully remove the positive cable from the battery terminal. Ensure that you do not allow the positive and negative terminals to touch each other or any metal components to avoid short circuits.

Step 4: Secure the Cables

After both cables are disconnected, it is important to secure them to prevent accidental contact with the battery terminals. You can use cable ties or tape to hold them in place, ensuring they are away from the battery.

Step 5: Remove the Battery

At this point, you can carefully remove the battery from its tray. Batteries can be heavy, so lift it with caution and place it aside in a safe location.

Remember to follow safety precautions when working with car batteries. Always disconnect the negative cable first and be cautious to avoid any sparks or short circuits. Additionally, if your Acura CL has any specific procedures for battery disconnection, be sure to refer to the owner's manual or consult a professional mechanic.

Remove rear seats

To remove the rear seats of a 2001 Acura CL, first move the two front seats forward to give yourself some extra room.

Now, you need to remove the rear seat cushion. Start by locating the seat cushion bolt on the right end of the cushion. Pull open the crevice between the cushion and the seat back to find it, then remove it with a socket wrench. Next, release the two latches beneath the seat cushion by pulling the release hatches forward to disengage them from their retaining hooks. With the bolt and latches released, you can now remove the seat cushion.

With the seat cushion removed, you can now remove the seat back. Start by removing five bolts with a socket wrench. Three of these bolts will be at the bottom of the seat back, and the other two are located below the headrest, which you can access by going through the folds in the upholstery.

Now that all the bolts are removed, carefully pull the seat back forward and out through one of the rear passenger doors.

And that's it! You have successfully removed the rear seats of your 2001 Acura CL.

Remove fuel pump assembly

To remove the fuel pump assembly from a 2001 Acura CL, you'll first need to disconnect the negative battery cable to prevent any electrical shorts and potential fires. Then, remove the rear seats to access the fuel pump access panel on the floorboard. With the seats removed, you'll be able to fold back the carpet flap and reveal the fuel pump cover.

Using a Phillips screwdriver, remove the screws securing the pump cover and use a small pry bar or screwdriver to pry it upwards for removal, as it has an adhesive backing. Disconnect the electrical harness plug and fuel line from the fuel pump.

Next, remove the lock ring from the fuel pump using a lock ring wrench, water pump pliers, or a drift punch and hammer. With the lock ring removed, lift the fuel pump assembly from the tank, tilting it to allow the fuel level sensor arm to clear the tank opening.

Before removing the old fuel pump assembly, clean the top of the assembly to ensure that no dirt or debris enters the fuel tank.

Reassembly

When reassembling your 2001 Acura CL, it is important to follow the correct steps to ensure that the fuel pump is installed properly and functions correctly. Here is a detailed guide on how to reassemble the fuel pump:

• Install the rubber sealing gasket onto the new fuel pump. Carefully slide the pump into the fuel tank, being cautious not to damage the fuel level sensor arm. Ensure that the pump is fully seated and positioned correctly to allow for the connection of the fuel line and electrical harness plug.
• Securely tighten the locking ring to prevent fuel leaks.
• If necessary, transfer the old fuel line quick-connect coupler to the new fuel pump nipple and attach the fuel line.
• Connect the fuel pump wiring harness plug.
• Reinstall the fuel pump cover and secure it with the fastening screws.
• Reinstall the rear seat and tighten the mounting bolts. Put back the plastic seat mount trim covers.
• Reconnect the battery.
• Before installing the cover, you can inspect the fuel pump for leaks by starting the car and examining it for wetness.

By following these steps, you can ensure that your 2001 Acura CL's fuel pump is properly reassembled and functioning as intended.

Reconnect the battery

To reconnect the battery of your 1997 Acura CL, you will first need to locate the battery. In some Acura CLs, the battery is located in the engine bay, but it may also be in the trunk, fender, or inside of the vehicle. Once you have located the battery, you can proceed to reconnect it.

Before reconnecting the battery, ensure that you have the correct security code for your radio from the owner's manual. This is important because, when you reconnect the battery, your radio presets are likely to be cleared. Additionally, your Acura's transmission may need to "re-learn" your driving style after the battery change, resulting in altered driving dynamics.

Now, to reconnect the battery, simply attach the terminals back to the battery. Make sure you do this step correctly, as a loose connection can cause a variety of electrical issues. Once the terminals are securely connected, start the car and check that all electrical components, such as headlights, interior lights, radio, etc., are functioning properly. If everything works as expected, your battery reconnection is complete!
