2001 Chrysler Sebring Fuel Pump Replacement: A Complete Step-by-Step Guide
If you own a 2001 Chrysler Sebring and your fuel pump has failed, the most important thing to know is that replacing the fuel pump is a job you can do yourself with basic mechanical skills and the right tools. The 2001 Chrysler Sebring uses an electric fuel pump located inside the fuel tank, and when it fails, the engine will crank but not start unless you spray starter fluid into the intake. The pump usually costs between $50 and $260 depending on the brand and whether you buy just the pump cartridge or the full assembly with the sending unit. This guide walks you through every step of the process, from diagnosing the problem to installing the new pump, so you can get your Sebring back on the road without paying a mechanic $500 or more.
Understanding the 2001 Chrysler Sebring Fuel Pump System
The 2001 Chrysler Sebring came with several engine options. The most common are the 2.4L four-cylinder engine and the 2.7L V6 engine . These engines use an electric fuel pump that sits inside the fuel tank. The pump pushes fuel from the tank to the engine at a pressure of around 58 PSI . The pump is part of a module assembly that also includes the fuel level sending unit, which tells your gas gauge how much fuel is in the tank.
The fuel pump system on the 2001 Sebring includes a fuel pump relay, a fuse, and a safety circuit that shuts off the pump if the engine stops rotating . This safety feature is important because it prevents the pump from running if the car is in an accident. The pump gets power through a relay in the fuse box under the hood. When you turn the key to the "run" position, the pump should run for about one second to prime the system. Then it runs continuously while the engine is cranking or running.
Signs Your Fuel Pump Is Failing
Before you start tearing apart your Sebring, you need to be sure the fuel pump is actually the problem. Here are the most common symptoms of a failing fuel pump on a 2001 Chrysler Sebring:
1. Engine cranks but won't start. This is the most obvious sign. If the engine turns over but never fires, and you have confirmed that the spark plugs are firing, the fuel pump is likely the issue. You can spray starter fluid into the intake. If the engine runs for a few seconds and then dies, the fuel pump is not delivering fuel .
2. No sound from the fuel tank when you turn the key. Have a helper turn the key to the "run" position while you listen near the fuel tank. You should hear a brief humming sound as the pump primes. If you hear nothing, the pump is not getting power, or the pump itself is dead .
3. Car stalls while driving, especially when accelerating hard. Some owners report that the car will run fine for a while, then die suddenly when they press the gas pedal hard. This is a classic sign of a failing fuel pump that cannot keep up with demand .
4. Loss of power under load. If the car feels sluggish and struggles to accelerate, the fuel pump may be delivering low pressure. This can cause the engine to run lean and lose power.
5. Check engine light with fuel pressure codes. A code reader may show codes related to fuel pressure. One 2001 Sebring owner reported a code indicating left and right side fuel rail high pressure, which is a strong indicator of fuel pump issues .
Step 1: Check the Fuses and Relays First
Do not skip this step. Many people replace the fuel pump only to find out the problem was a blown fuse or a bad relay. The fuel pump on the 2001 Chrysler Sebring has two key fuses and one relay.
Fuse 8 provides voltage to the fuel pump relay. Fuse 23 is needed to close the relay contacts. If either fuse is blown, the pump will not run . Check both fuses with a test light or a multimeter. Do not just look at them. A fuse can look good but still be blown.
The fuel pump relay is located in the power distribution box under the hood. The relay pins are numbered 30, 85, 86, 87, and 87a. Pin 30 is hot with the key on. When the relay is activated, pin 30 connects to pin 87, which sends power to the fuel pump. To test the relay, you can swap it with the same type of relay from another system in the fuse box, such as the horn relay. If the pump starts working, the relay was bad.
You can also test the circuit by jumping pin 30 to pin 87 in the relay socket. If the pump runs when you do this, the wiring to the pump is good, and the problem is in the relay or the control circuit .
Step 2: Release Fuel System Pressure
Before you work on the fuel system, you must release the pressure. The fuel system on the 2001 Sebring operates at about 58 PSI. If you disconnect a fuel line without releasing pressure, fuel will spray everywhere and create a fire hazard.
To release the pressure, locate the fuel pump relay in the fuse box. Remove the relay. Then start the engine and let it run until it stalls. Crank the engine for a few more seconds to make sure all pressure is gone. Turn the ignition off and reinstall the relay. This step is important for safety.
Step 3: Disconnect the Battery
Disconnect the negative battery cable using a socket wrench. This prevents any electrical shorts or sparks while you are working near the fuel tank. It also resets the engine control module, which can help with diagnostics later.
Step 4: Drain the Fuel Tank
You will need to drain the fuel tank before you remove it. You can do this by siphoning the fuel out through the filler neck or by using the fuel pump itself to pump the fuel out. If you use the fuel pump, you need to jump the relay to make the pump run. Disconnect the fuel line at the engine and route it into a fuel-safe container. Apply 12 volts to the fuel pump relay pins to run the pump and drain the tank.
If your pump is already dead, you will have to siphon the fuel out. Use a hand siphon pump to remove as much fuel as possible. A full tank is very heavy and difficult to lower safely.
Step 5: Raise the Vehicle and Support the Fuel Tank
Jack up the rear of the vehicle and place it on jack stands. Make sure the car is stable and secure. Never work under a car supported only by a jack.
The fuel tank is located under the rear of the car. Place a transmission jack or a floor jack with a block of wood under the fuel tank to support its weight. The fuel tank straps hold the tank in place. Use a socket wrench to remove the bolts from the fuel tank straps . Once the bolts are removed, the tank will rest on your jack.
Step 6: Disconnect the Fuel Lines and Electrical Connector
Before you lower the tank, you need to disconnect everything that connects the tank to the car.
Fuel filler tube: Loosen the clamp that holds the rubber filler hose to the tank. Slide the hose off the tank neck.
Fuel line: The fuel line uses a quick-connect fitting. Squeeze the plastic retainers on the fitting and pull the line off the fuel pump module. Be careful not to damage the plastic retainers.
Vapor line and vacuum line: There is a vapor line that connects to the top of the tank. Disconnect it by pulling off the rubber hose. Some models also have a vacuum line that needs to be removed.
Electrical connector: The fuel pump has a wiring harness that plugs into the top of the pump module. Push down on the retainer tab and pull the connector off. The connector is usually held in place by a locking tab that you must press or lift to release .
Step 7: Lower the Fuel Tank
With everything disconnected, slowly lower the jack to bring the fuel tank down. You may need a helper to guide the tank as it comes down. The tank is awkward and heavy, even when empty. Once the tank is on the ground, slide it out from under the car.
Step 8: Mark the Fuel Pump Location
Before you remove the old pump, note the position of the pump module in the tank. The module has a specific orientation. Mark the tank and the pump flange with a marker or a scribe so you can install the new pump in the same position. This ensures the fuel pickup tube sits in the correct spot inside the tank.
Step 9: Remove the Fuel Pump Lock Ring
The fuel pump is held in place by a large lock ring. This ring is usually a metal ring with tabs that fit into slots on the tank. To remove it, use a brass punch and a hammer. Tap the ring counterclockwise to loosen it. A brass punch is recommended because it will not spark and will not damage the ring or the tank .
Once the ring is loose, lift it out of its groove. Then lift the fuel pump module straight out of the tank. Be careful not to bend the fuel level float arm. The module will have a rubber O-ring seal around the top edge. Remove and discard this O-ring. Never reuse an old O-ring.
Step 10: Inspect the Fuel Tank
Before you install the new pump, look inside the fuel tank. Check for debris, rust, or sediment. Fuel contamination is the leading cause of premature fuel pump failure. If the tank is dirty, you should clean it before installing the new pump. Some manufacturers recommend using a fuel tank cleaning kit to remove any contamination . If you see rust or heavy debris, you may need to replace the tank.
Step 11: Install the New Fuel Pump
Now you can install the new fuel pump. If you bought a complete fuel pump module assembly, the installation is straightforward. Place the new O-ring seal into the groove on the tank. Make sure it sits evenly. Lower the new pump module into the tank, aligning it with the marks you made earlier. Press the module down firmly.
Install the lock ring by tapping it clockwise with the brass punch and hammer. Make sure the ring seats fully into the groove. The ring should be tight enough that the pump module cannot move.
Step 12: Reinstall the Fuel Tank
With the new pump in place, lift the fuel tank back into position under the car. Reconnect the fuel filler tube, the fuel line, the vapor line, and the electrical connector. Make sure the quick-connect fittings click into place. Pull on them gently to confirm they are secure.
Install the fuel tank straps and tighten the bolts to 40 foot-pounds using a torque wrench. Do not overtighten these bolts. The fuel tank straps need to hold the tank securely but not crush it. Tighten the fuel filler hose clamp to 32 inch-pounds with a torque wrench .
Step 13: Reconnect the Battery and Test
Reconnect the negative battery cable. Turn the key to the "run" position but do not start the engine. Listen for the fuel pump to prime. You should hear a brief hum from the fuel tank. If you hear the pump, turn the key to "start" and crank the engine. It may take a few seconds for the fuel pressure to build, but the engine should start and run smoothly.
If the engine still does not start, check for fuel pressure at the fuel rail. If you have no fuel pressure, the pump may not be getting power. Check the wiring and the relay again. If the pump runs but the engine still does not start, the problem may be elsewhere, such as the crank sensor or cam sensor .
Choosing the Right Fuel Pump for Your 2001 Chrysler Sebring
The 2001 Chrysler Sebring can use a 2.4L four-cylinder engine or a 2.7L V6 engine. You need to know your engine size before buying a replacement pump. The fuel pump for the 2.4L engine is different from the pump for the 2.7L engine .
There are two types of fuel pump replacements:
1. Fuel pump cartridge only. This is just the pump itself. You reuse your existing fuel pump module assembly and replace only the pump. This is cheaper but requires you to disassemble the module, which can be tricky.
2. Complete fuel pump module assembly. This includes the pump, the fuel level sending unit, the strainer, and the O-ring seal. This is the easier option because you simply swap the entire module. It costs more but saves time and ensures a proper fit.
Several brands make fuel pumps for the 2001 Chrysler Sebring. Walbro offers an OEM-spec fuel pump kit for the 2.4L engine, part number TU146, which costs about $258 . For the 2.7L engine in the convertible model, Walbro offers part number GCA785 for about $136 . Carter makes a complete module assembly, part number P75025M, that fits both the 2.4L and 2.7L engines and costs about $154 . Delphi offers an in-tank electric fuel pump that fits multiple years and engine sizes, including the 2001 model, for about $142 . Spectra Premium makes the SP7038M assembly, which fits the 2001 Sebring 2.4L and costs about $58 .

Common Mistakes to Avoid
1. Not checking the fuses and relay first. This is the most common mistake. A blown fuse or a bad relay can mimic a dead fuel pump perfectly. Always check the electrical system before you drop the fuel tank.
2. Reusing the old O-ring seal. The O-ring seal between the fuel pump module and the tank must be replaced every time you remove the pump. An old, hardened O-ring will leak fuel and cause a fire hazard.
3. Forgetting to clean the fuel tank. Fuel contamination is the leading cause of premature fuel pump failure. If there is dirt, rust, or debris in the tank, the new pump will suck it up and fail quickly. Clean the tank before installing the new pump.
4. Not supporting the fuel tank properly. A fuel tank full of gasoline weighs over 100 pounds. If you do not support it properly, the straps can break, and the tank can fall on you. Always use a jack or a transmission jack to support the tank.
5. Tightening the tank strap bolts too much. The tank strap bolts should be tightened to 40 foot-pounds, not full torque. Overtightening can crush the tank or strip the threads.
6. Forgetting to prime the pump. After installation, turn the key to the "run" position for a few seconds before starting the engine. This allows the pump to build pressure and prevents the engine from running dry.
Final Thoughts
Replacing the fuel pump on a 2001 Chrysler Sebring is a straightforward job that most DIY mechanics can handle in a weekend. The key to success is proper diagnosis. Check the fuses and relays first, then listen for the pump to prime, and only then drop the fuel tank. Once you have the new pump installed, take your time with the reassembly. Make sure all connections are secure, and double-check the O-ring seal.
