2007 Chrysler Sebring Fuel Pump Replacement: A Complete Step-by-Step Guide

If your 2007 Chrysler Sebring is stalling at stop lights, cranking for a long time before it starts, or making a loud whining noise from the rear of the car, the fuel pump is likely failing and needs to be replaced. The good news is that on the 2007 Sebring, the fuel pump is accessible from under the rear seat, which means you can replace it without dropping the fuel tank. This guide walks you through everything you need to know, from confirming the diagnosis to choosing the right replacement part and completing the job safely.

The 2007 Chrysler Sebring was produced in sedan, convertible, and coupe body styles with different engines, and the fuel pump replacement procedure is similar across these variants. The pump itself sits inside the fuel tank, submerged in gasoline, and its only job is to deliver fuel to the engine at the correct pressure. When it wears out, the engine gets starved of fuel, which leads to the symptoms listed above. Ignoring a failing fuel pump is not recommended because the engine can stall unexpectedly in traffic, creating a serious safety hazard. Replacing the pump is a job that a confident DIYer can complete in about two to three hours with basic hand tools.

How to Tell If Your Fuel Pump Is Going Bad

Before you buy any parts, you need to be certain the fuel pump is actually the problem. On the 2007 Sebring, there are several well-documented symptoms that point to fuel pump failure. The most common ones include:

1. Engine stalling or sputtering. The engine may cut out suddenly while driving, especially when it is hot or under load. The car might restart after cooling down for a few minutes, which is a classic sign of a pump that is overheating. This is the most dangerous symptom because it can happen in traffic or on the highway.

2. Difficulty starting the engine. If the car cranks for an extended period before it finally fires up, the fuel pump may not be building enough pressure in the fuel lines. In the final stages of failure, the engine will crank but never start at all.

3. A loud whining noise from the fuel tank. A healthy fuel pump makes a quiet hum when you first turn the key to the ON position. If you hear a loud, high-pitched whine coming from the rear of the vehicle, the pump motor is strained and likely failing.

4. Loss of power under acceleration. The engine may feel sluggish, struggle to climb hills, or hesitate when you press the gas pedal. A weak pump cannot keep up with the increased fuel demand during hard acceleration or when towing.

Important note about the 2007 Sebring: There is a specific and well-known failure mode on this model year. The electrical connector on top of the fuel pump module can overheat and melt. This can cause the wires to burn and, in some cases, create a fire hazard. If you are experiencing intermittent stalling and your car has high mileage, it is worth inspecting the connector before condemning the pump itself. Many owners have reported that the fuel pump pin melted out of the module, and the repair required replacing both the fuel pump and the wiring harness.

Where the Fuel Pump Relay and Fuses Are Located

Before you start the replacement, it is also wise to rule out a simpler problem: a blown fuse or a faulty fuel pump relay. On the 2007 Sebring, the fuel pump relay is located inside the Totally Integrated Power Module, which is the main fuse box in the engine compartment near the air cleaner assembly. The relay is not serviceable separately on many models because it is integrated into the TIPM, but you should still check the fuses.

The fuel pump is not protected by a dedicated fuse labeled "fuel pump" in the TIPM. Instead, it is powered through the ASD (Auto Shut Down) relay. In the 2007 model year, the ASD relay feeds several circuits, and the fuel pump receives power through this relay. If you want to verify the fuel pump is getting power, you can do a simple test: turn the key to the ON position without cranking the engine. You should hear the fuel pump prime for about one to two seconds. If you do not hear it, check the ASD relay and related fuses first.

There are also two fuse boxes in the passenger compartment. On the sedan and convertible, the fuse access panel is located at the left side of the instrument panel; on the coupe, the fuse block is on the driver's side. If your fuel pump is completely dead, checking these fuses first is a quick and free step that can save you from buying an unnecessary pump.

Gathering the Right Parts and Tools

The fuel pump for the 2007 Sebring is an electric pump that sits inside the fuel tank, and it is part of a larger assembly called the fuel pump module. This module includes the pump, the fuel level sender, and the strainer. When you buy a replacement, you have a few options:

1. Buy a complete fuel pump module assembly. This is the easiest route. The entire assembly comes ready to install, including the pump, sender, and float. You simply remove the old unit and install the new one. This is the recommended approach because the fuel level sender is a common failure point as well, and replacing the whole module addresses both issues at once.

2. Buy just the fuel pump. If your fuel level gauge still works fine and your only problem is the pump not delivering fuel, you can buy just the pump and swap it into your existing module. This is cheaper but requires more labor because you must disassemble the module carefully.

3. Check for your specific engine and drivetrain. The 2007 Sebring came with a 2.4L four-cylinder, a 2.7L V6, and a 3.5L V6, plus a coupe version that used different components. The fuel pump design varies significantly by engine type and whether the car is front-wheel drive or all-wheel drive. On the Sebring, the pump assembly also varies by emissions system (PZEV vs. non-PZEV). You must verify your car's exact configuration before ordering a replacement part to avoid fitment issues.

Tools you will need:

  • A flathead screwdriver or trim removal tool
  • A 10mm socket with extension
  • A ratchet
  • A small pick or pliers
  • A clean rag or shop towels
  • A fuel line disconnect tool (if your car uses quick-connect fittings)
  • A new fuel pump module or pump assembly
  • A new fuel pump gasket or seal (often included with the module)
  • Safety glasses and nitrile gloves

Preparing the Car and Removing the Rear Seat

Safety first. Before you start any work on the fuel system, disconnect the negative battery terminal. Gasoline is extremely flammable, and you do not want any sparks while you are working near the fuel tank. Also, depressurize the fuel system. The easiest way to do this is to remove the fuel pump fuse or relay, then start the engine and let it run until it stalls. This releases the pressure in the fuel lines. If the car will not start, you can skip this step, but be aware that some pressure may still be in the lines.

Once the battery is disconnected and the fuel pressure is relieved, remove the rear seat cushion. On the 2007 Sebring sedan and convertible, the rear seat bottom simply pulls up and out. There are two clips near the front edge of the seat. Grab the seat firmly at the front, lift up sharply, and it should pop free. On some models, there may be a 10mm bolt holding the seat in place.

With the seat removed, you will see a metal access panel on the floor. This is the fuel pump access cover. On the 2007 Sebring, replacement is accessible under the rear seat, which makes the job significantly easier than on earlier models that required dropping the fuel tank. Remove the screws or bolts holding the panel in place, then lift the panel off. You will now see the top of the fuel pump module, which is the round black ring with wires and hoses connected to it.

Removing the Old Fuel Pump Module

Now you are ready to remove the old pump. Follow these steps carefully:

1. Clean the area around the pump. Before you disconnect anything, use a rag or shop towel to wipe away any dirt and debris from the top of the fuel pump module. You do not want any contamination falling into the fuel tank when you open it.

2. Disconnect the electrical connector. The wiring harness is connected to the top of the module. Depress the locking tab and pull the connector straight off. On the 2007 Sebring, this connector is the one that is prone to melting, so inspect it carefully. If the connector or the terminals look burned or melted, you will need to replace the wiring harness as well.

3. Disconnect the fuel lines. There are two fuel lines connected to the module: a supply line and, on some models, a return line. They use quick-connect fittings. Push the release tab and pull the line off, or use a fuel line disconnect tool to release the fitting. Be prepared for a small amount of fuel to spill out, so keep a rag handy.

4. Remove the retaining ring. The fuel pump module is held in place by a large plastic ring or a metal lock ring. Use a hammer and a flathead screwdriver or a specialized fuel pump lock ring tool to tap the ring counterclockwise. This ring can be tight, so take your time. Once it is loose, lift the ring off.

5. Lift the module out. Carefully lift the fuel pump module straight up and out of the tank. It may take some wiggling to get it past the opening. Be gentle with the float arm on the fuel level sender so you do not bend it. Once the module is out, set it aside. You will see the fuel remaining in the tank below. If the tank is more than a quarter full, you may want to siphon some fuel out first to make the removal easier and to reduce the chance of spills.

6. Transfer the rubber gasket. The old module has a rubber gasket that seals the top of the tank. You will need to reuse this gasket or use the new one that comes with your replacement module. If you are reusing the old one, inspect it for cracks or damage and replace it if necessary.

Installing the New Fuel Pump Module

Installation is essentially the reverse of removal, but there are a few important details:

1. Align the module correctly. The new module has a tab or a notch that must align with a slot in the fuel tank. Look at the tank opening and the module to find the alignment points. If you do not align them properly, the float arm will not work correctly and the module may not sit flat.

2. Insert the module into the tank. Carefully lower the module into the fuel tank. Make sure the float arm is not bent and that it moves freely as the module goes in. Push down gently until the module sits flush with the tank surface.

3. Install the retaining ring. Place the retaining ring back on top and turn it clockwise to tighten it. Use your hammer and screwdriver or the lock ring tool to tap it into place. Do not overtighten, as this can crack the ring or the tank flange.

4. Reconnect the fuel lines. Push the quick-connect fittings back onto the module until they click into place. Pull on them gently to make sure they are secure.

5. Reconnect the electrical connector. Plug the wiring harness back into the module. Make sure the connector seats fully and the locking tab clicks into place. If the connector on the harness side was damaged, you must repair or replace it before continuing. This is the exact point where many 2007 Sebrings fail, so do not skip this inspection.

6. Reinstall the access panel and rear seat. Place the metal access cover back over the opening and secure it with the screws or bolts. Then press the rear seat cushion back into place, making sure the clips snap in securely.

Testing Your Work and Reassembly

After the new pump is installed, it is time to test everything. Follow these steps:

1. Reconnect the negative battery terminal.

2. Turn the key to the ON position without cranking the engine. You should hear the fuel pump prime for one to two seconds. This confirms the pump is getting power and running.

3. Check for fuel leaks. While the pump is priming, and again after you start the engine, inspect the area around the fuel pump module for any signs of fuel leakage. A small drip means a fitting is not sealed properly. Fix any leaks before driving.

4. Start the engine. It may take a few extra cranks the first time while the fuel system builds pressure. Once it starts, let it idle for a few minutes and check for leaks again.

5. Verify the fuel gauge works. Since the fuel level sender is part of the new module, check the gauge to make sure it reads correctly. If you had a full tank, the gauge should show full. If the gauge is inaccurate, the float arm may be bent or the module may not be aligned correctly.

6. Take a short test drive. Drive the car for about ten minutes, including some acceleration and deceleration. Pay attention to how the car feels. It should accelerate smoothly without hesitation, and there should be no whining noise from the rear of the car.

What It Costs to Replace a Fuel Pump on a 2007 Sebring

The total cost of this repair depends on whether you do it yourself or hire a shop.

If you do it yourself: The parts cost for a new fuel pump module is typically between $100 and $250 for an aftermarket OEM replacement unit. You will also need to budget for a few small items like a new gasket or lock ring if they are not included. The total DIY cost is usually around $150 to $300.

If you hire a professional: Shop labor rates for this job typically range from $150 to $450, depending on where you live. When you add the cost of the parts, the total bill at a shop will likely be between $400 and $700. The labor is lower on the 2007 Sebring than on earlier models because the tank does not need to be dropped, which saves significant shop time.

A note about the fuel pump connector: If your car has the melted connector problem, you will also need to replace the fuel pump wiring harness. This harness is separate from the pump itself and adds to the cost. On the 2007 Sebring, the connector is a known problem, and it is worth replacing the harness preventively while you have everything apart, even if the connector looks okay.

Common Mistakes to Avoid

Many DIYers make a few common mistakes when replacing the fuel pump on a 2007 Sebring. Avoiding these will save you time and frustration:

1. Skipping the fuel pressure release. If you do not depressurize the system, fuel will spray out when you disconnect the lines. This is messy and dangerous. Always remove the fuel pump fuse and crank the engine until it stalls before starting.

2. Buying the wrong pump. The Sebring has multiple engine options, and the pump assembly varies by engine and emissions package. Order a pump specifically for your engine size and drivetrain. Double-check the part number against your VIN before installing.

3. Reusing a melted connector. If the old electrical connector shows signs of heat damage, do not reuse it. The new pump will run hotter than the old one if the pump is working harder, and the melted connector is often the root cause of the failure. Replace the harness if there is any doubt.

4. Forgetting the fuel filter. The fuel filter is usually part of the pump module, but on some models it may be a separate item in the fuel line. If you have not changed the filter in a long time, consider replacing it while you are working on the fuel system.

5. Not checking the ground connection. A bad ground can cause the pump to run weakly and overheat. Make sure the ground wire at the rear of the car is clean and tight before you button everything up.
