2000 Chrysler Cirrus Fuel Pump: The Complete Guide to Symptoms, Replacement, and Best Options
The bottom line: If your 2000 Chrysler Cirrus 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 the most likely culprit. Replacing it with a high-quality OEM replacement unit is the only reliable fix. We recommend the KEMSO brand for its proven performance, exact fit, and lifetime warranty.
Understanding the 2000 Chrysler Cirrus Fuel Pump System
The 2000 Chrysler Cirrus was offered with two engine options: the 2.4L 4-cylinder and the 2.5L V6. Both engines use an electric fuel pump located inside the fuel tank. This pump is responsible for delivering fuel from the tank to the engine at the correct pressure. On the 2000 Cirrus, the fuel pressure regulator is part of the fuel pump module assembly, which means the entire module must be replaced if the pump fails.
The fuel pump module includes the pump itself, the fuel level sending unit, the fuel pressure regulator, and the fuel filter. Many owners do not realize that the fuel filter is not serviceable separately on this vehicle. When the pump goes bad, you replace the whole assembly. This is important because a clogged filter can cause the pump to work harder and fail prematurely.
Common Symptoms of a Failing Fuel Pump in a 2000 Chrysler Cirrus
Recognizing the signs of a bad fuel pump early can save you from being stranded on the side of the road. Here are the most common symptoms you will experience with a 2000 Chrysler Cirrus:
1. Engine Cranks But Does Not Start
This is the most obvious symptom. You turn the key, the engine cranks over normally, but it never fires up. You may hear the fuel pump prime for a few seconds when you first turn the key to the "on" position. If you do not hear that priming sound, the pump is likely dead.
2. Sputtering or Stalling at High Speeds
A failing pump cannot maintain consistent fuel pressure. When you accelerate on the highway or drive uphill, the engine may sputter, hesitate, or lose power. This happens because the pump cannot deliver enough fuel to meet the engine's demand.
3. Loss of Power on Steep Grades
If your 2000 Cirrus struggles to climb hills or feels like it is running out of gas even with a full tank, the fuel pump is failing. The pump has to work harder to push fuel uphill, and a weak pump will fail under that load.
4. Whining Noise from the Fuel Tank
A healthy fuel pump makes a quiet humming sound. A loud whining or buzzing noise coming from the rear of the car, especially when you first start the engine, indicates the pump bearings are wearing out. This noise will get louder over time until the pump fails completely.
5. Surging or Inconsistent Idle
When the fuel pump cannot deliver a steady stream of fuel, the engine may surge at idle. You will notice the RPMs rising and falling without you touching the gas pedal. This is often accompanied by a rough idle.
6. Check Engine Light Turns On
The 2000 Cirrus has an OBD-II diagnostic system. A failing fuel pump often triggers a check engine light with codes related to fuel pressure or lean fuel mixture. Common codes include P0087 (Fuel Rail Pressure Too Low) or P0171 (System Too Lean).
How to Test the Fuel Pump on a 2000 Chrysler Cirrus
Before you buy a new pump, you should confirm the diagnosis. Here is a simple test you can do:
1. Listen for the Prime
Turn the ignition key to the "on" position without starting the engine. Listen for a 2-3 second humming sound from the rear of the car. If you hear it, the pump is getting power and running. If you do not hear it, check the fuel pump relay and fuse first.
2. Check the Fuel Pump Relay and Fuse
Locate the fuse box under the hood. The fuel pump relay is usually labeled. Swap it with a similar relay from the horn or air conditioning system. If the pump starts working, the relay was bad. The fuel pump fuse is also in the same box. A blown fuse will stop the pump completely.
3. Use a Fuel Pressure Gauge
This is the most accurate test. Connect a fuel pressure gauge to the test port on the fuel rail. The 2000 Cirrus should have 49-52 psi of fuel pressure at idle. If the pressure is below 45 psi, the pump is weak. If the pressure drops quickly after turning off the engine, the check valve in the pump is bad.
How to Replace the Fuel Pump on a 2000 Chrysler Cirrus
Replacing the fuel pump on a 2000 Chrysler Cirrus is a job that most DIY mechanics can handle. The pump is accessible through an access panel under the rear seat. You do not need to drop the fuel tank. This makes the job much easier than on many other cars.
Tools and Parts You Will Need:
- New fuel pump module assembly (KEMSO brand recommended)
- Socket set with extensions
- Flathead screwdriver
- Hammer and punch (for lock ring removal)
- Shop rags
- Safety glasses
- Fire extinguisher (safety first)
Step-by-Step Replacement Process:
1. Relieve Fuel System Pressure
Locate the fuel pump fuse in the fuse box and remove it. Start the engine and let it run until it stalls. Turn the key off. This relieves pressure in the fuel lines. Disconnect the negative battery terminal.
2. Access the Fuel Pump
Remove the rear seat cushion. It simply pulls up and out. You will see a metal access cover on the floor pan. Remove the screws holding this cover in place. You will now see the top of the fuel pump module.
3. Disconnect Electrical and Fuel Lines
There is a wiring harness connector on top of the pump module. Press the tab and pull it apart. There are two fuel lines: a supply line and a return line. On the 2000 Cirrus, these are quick-connect fittings. Press the release tabs and pull the lines off. Have a rag ready because some fuel will spill.
4. Remove the Lock Ring
The fuel pump is held in place by a large metal lock ring. Use a hammer and punch to tap the ring counterclockwise. It may be tight, but it will loosen. Once it is free, lift the ring off.
5. Remove the Old Pump Module
Carefully lift the old pump assembly out of the tank. Tilt it to allow the float arm to clear the tank opening. Note the orientation of the rubber gasket at the top of the tank. You will reuse this gasket or install a new one.
6. Install the New Pump Module
Transfer the rubber gasket to the new KEMSO fuel pump module. Lower the new pump into the tank in the same orientation as the old one. Make sure the float arm is not bent. Press the assembly down until it sits flush.
7. Install the Lock Ring
Place the lock ring back on top of the pump module. Tap it clockwise with the hammer and punch until it is tight. Do not overtighten, as you can damage the plastic housing.
8. Reconnect Everything
Reconnect the fuel lines. Push them on until they click. Reconnect the electrical connector. Install the access cover and screws. Reinstall the rear seat cushion. Put the fuel pump fuse back in. Reconnect the battery.
9. Prime the System
Turn the key to the "on" position for 3 seconds, then turn it off. Repeat this 3-4 times to prime the system. Check for fuel leaks at the fuel line connections. Start the engine and let it idle. Check for leaks again.
Cost of a 2000 Chrysler Cirrus Fuel Pump Replacement
The cost of replacing the fuel pump on a 2000 Chrysler Cirrus depends on whether you do it yourself or hire a mechanic.
DIY Cost:
- A quality replacement fuel pump module costs between $65 and $120.
- You need no special tools beyond basic hand tools.
- Total cost: $65 to $120.
Professional Mechanic Cost:
- Parts markup: $100 to $180.
- Labor: 1.5 to 2 hours at $100 to $150 per hour.
- Total cost: $250 to $480.
Important: Cheap fuel pumps from online marketplaces can cost as little as $30. These pumps often fail within months. You will end up paying twice for labor if you use a cheap part. Spending a little more on a quality pump like KEMSO saves you money in the long run.
Why Choosing the Right Fuel Pump Matters
The 2000 Chrysler Cirrus is a 26-year-old car. The original fuel pump has long exceeded its expected lifespan. When you replace it, you want a pump that will last another 10-15 years. Here is what to look for in a replacement:
OEM Replacement vs. Generic
An OEM replacement pump is built to the same specifications as the original part. It will have the correct fuel pressure, flow rate, and electrical connections. Generic pumps often have different dimensions or lower quality internal components. They may require modifications to fit, or they may not deliver the correct fuel pressure.
Fuel Pump Module vs. Pump Only
On the 2000 Chrysler Cirrus, you should replace the entire module. The module includes the fuel pressure regulator, the fuel level sending unit, and the fuel filter. If you replace only the pump, the old regulator may fail soon after, or the old filter may restrict fuel flow and damage the new pump. Replacing the whole module is more expensive upfront but cheaper in the long run.
Warranty and Support
A good fuel pump comes with a warranty. This gives you peace of mind. If the pump fails within the warranty period, you get a replacement at no cost. Some brands offer limited warranties of 1-2 years. Others offer lifetime warranties.

Preventative Maintenance for Your 2000 Chrysler Cirrus Fuel System
After replacing your fuel pump, you can take steps to make it last longer.
1. Keep the Fuel Tank at Least Half Full
Running the tank low on fuel causes the pump to work harder. The pump relies on fuel for cooling and lubrication. When the tank is low, the pump is exposed to air and can overheat. Try to refill when the tank reaches a quarter full.
2. Use Quality Fuel
Cheap gas stations may have water or contaminants in their fuel. Water can cause internal corrosion in the pump. Use fuel from a reputable station. If you are concerned about ethanol, consider using a fuel stabilizer that counteracts ethanol's effects.
3. Replace the Fuel Filter
While the 2000 Cirrus has a non-serviceable fuel filter inside the module, you can still replace the fuel filter if your car has an external one. Some models have a small inline filter. Check your owner's manual. If you have one, replace it every 30,000 miles.
4. Listen for Changes
After installing a new pump, pay attention to the sound it makes. A healthy pump makes a quiet, steady hum. If you hear any whining or buzzing, the pump may be failing. Catching it early prevents a breakdown.
