2001 Acura CL Fuel Pump: Complete Guide to Symptoms, Replacement, and Best Options
The bottom line: If your 2001 Acura CL is hard to start, stalls while driving, loses power on hills, or makes a whining noise from the rear of the car, the fuel pump is likely failing. Replacing it yourself can save you hundreds of dollars in labor costs, and choosing a high-quality aftermarket pump like KEMSO gives you better performance, a perfect fit, and a lifetime warranty—all at a fraction of the dealer price.
Signs Your 2001 Acura CL Fuel Pump Needs Replacement
Before you order a new pump, it helps to confirm that the fuel pump is actually the problem. The 2001 Acura CL uses an in-tank electric fuel pump, and when it starts to fail, you will notice one or more of these symptoms:
1. Engine cranks but does not start. This is the most common symptom. The starter turns the engine over, but the engine does not fire because no fuel is reaching the injectors. You can test this by turning the key to the "ON" position and listening for a brief hum from the rear of the car—that is the pump priming. If you hear nothing, the pump or its electrical circuit may be dead.
2. The car hesitates or sputters during acceleration. A failing pump cannot maintain consistent fuel pressure, causing the engine to hesitate when you press the gas. This is especially noticeable when merging onto a highway or climbing a steep grade.
3. The engine stalls at high speeds. The pump may run fine at low speeds but fail when the engine demands more fuel. If your CL stalls after driving at highway speeds for a while, the pump is likely overheating or struggling to keep up.
4. The car has a hard time starting after sitting for a while. The pump may be losing its prime, allowing fuel to drain back into the tank. This means you have to crank the engine several times before it fires up.
5. You hear a whining noise from the fuel tank. A healthy fuel pump makes a quiet hum. A loud whining or buzzing noise means the pump is wearing out and should be replaced soon.
It is also worth checking the fuel pump relay and the fuel filter before condemning the pump. A bad relay can mimic a dead pump, and a clogged filter can cause similar symptoms. The relay on a 2000 Ford Taurus is located in the power distribution box, but for the 2001 Acura CL, the relay is typically in the under-dash fuse box or the engine compartment fuse box—check your owner's manual for the exact location.
What You Need to Know Before You Start
The 2001 Acura CL fuel pump is located inside the fuel tank. To access it, you will need to remove the rear seat cushion to reach the access panel on top of the tank. This is a common design for Honda and Acura vehicles of this era, and it makes the job much easier than dropping the tank.
Important safety precautions:
- Work in a well-ventilated area. Gas fumes are heavy and can accumulate in low spots. If you are working in a garage, open the door.
- Keep a fire extinguisher nearby. This is a good practice for any automotive work, but especially for fuel system work.
- Do not smoke or use any open flames near the work area.
- Relieve fuel system pressure before disconnecting any lines. You can do this by removing the fuel pump fuse and cranking the engine for a few seconds.
The Cost of Replacing the Fuel Pump
The cost of a fuel pump for a 2001 Acura CL varies depending on the brand and whether you buy just the pump or the entire module assembly.
- A standalone pump (just the electric pump itself) typically costs between $40 and $80.
- A complete module assembly with the pump, sender, strainer, and pressure regulator costs between $100 and $200.
- Labor cost at a shop is usually $200 to $400, bringing the total to $300 to $600 for a professional replacement.
Doing the job yourself saves the labor cost and only requires the cost of the pump and a few basic tools. The 2001 Acura CL is a straightforward vehicle to work on, and most DIYers with basic mechanical skills can complete the job in a weekend.
Step-by-Step Overview of the Replacement Process
Here is a high-level overview of what the job involves. Always consult a service manual for your specific vehicle before starting.
1. Relieve fuel system pressure. Remove the fuel pump fuse from the fuse box. Start the engine and let it run until it stalls. Crank the engine a few more times to ensure all pressure is gone. Disconnect the negative battery terminal.
2. Remove the rear seat cushion. The seat cushion typically pulls up and out. On some models, you may need to remove a few bolts.
3. Remove the access cover. You will see a metal or plastic cover plate on the floor pan under the seat. Remove the screws or bolts to access the top of the fuel tank.
4. Disconnect the electrical connector and fuel lines. The fuel pump module has a wiring harness connector and two fuel lines (supply and return). Mark the lines so you know which is which. Use a fuel line disconnect tool if necessary. Be prepared for a small amount of fuel to spill.
5. Remove the retaining ring. The fuel pump module is held in place by a large locking ring. Use a hammer and a blunt punch or a special fuel pump ring tool to turn the ring counterclockwise. If the ring is cracked, you will have a fuel leak.
6. Lift out the old module. Carefully pull the module straight up out of the tank. The fuel level sender arm may catch on the tank opening, so tilt the module slightly as you remove it.
7. Transfer components to the new module. If you bought a complete module assembly, you can skip this step. If you bought just the pump, you will need to disassemble the old module and install the new pump into the existing housing. This usually involves removing a few screws, disconnecting the old pump, and installing the new one with new O-rings and strainers.
8. Install the new module. Lower the new module into the tank, making sure the fuel level sender arm is not bent. Align the index marks on the module and the tank, then install the retaining ring and tighten it to the manufacturer's specification (usually around 30 to 40 foot-pounds).
9. Reconnect everything. Attach the fuel lines, plug in the electrical connector, and reinstall the access cover and seat cushion.
10. Test the system. Reconnect the battery. Turn the key to the "ON" position but do not start the engine. Listen for the pump to prime for 2-3 seconds. Check for fuel leaks at the connections. Start the engine and let it idle. Check for leaks again. Take the car for a short test drive to confirm the pump is working properly.

Final Tips for a Successful Fuel Pump Replacement on Your 2001 Acura CL
Removing the fuel pump on a 2001 Acura CL is a job that most DIYers can handle in a weekend. The key is to take your time, follow the steps in order, and prioritize safety. Here are a few final tips to make the job go smoothly:
- Work in a well-ventilated area. Gas fumes are heavy and can accumulate in low spots. If you are working in a garage, open the door.
- Keep a fire extinguisher nearby. This is a good practice for any automotive work, but especially for fuel system work.
- Do not smoke or use any open flames near the work area.
- Clean the area around the fuel pump module before removing it. Dirt and debris can fall into the tank and damage the new pump.
- Use a torque wrench if you have one. The retaining ring should be tightened to the manufacturer's specification, which is usually around 30 to 40 foot-pounds. If you do not have a torque wrench, tighten it firmly by hand and then give it a quarter turn with a tool.
- Replace the fuel filter at the same time. A clogged fuel filter can put extra strain on a new pump. It is cheap insurance and only takes a few minutes.
- Check the fuel pump relay. If the new pump does not run, the relay may be bad. A relay costs only a few dollars and can prevent unexpected breakdowns.
Frequently Asked Questions
Q: How long does a fuel pump last on a 2001 Acura CL?
A: Fuel pumps typically last between 100,000 and 150,000 miles. If your CL has over 100,000 miles on the original pump, it is a good idea to consider replacing it proactively.
