2002 Chrysler Sebring Fuel Pump Relay Location: Quick Guide and Complete Diagnosis

The bottom line: The fuel pump relay on a 2002 Chrysler Sebring is located in the underhood power distribution center (fuse box) near the air cleaner assembly. For the sedan model, it is labeled as relay R10 or R3 depending on the specific fuse box layout, and for the coupe model, the fuel pump relay is typically found on the junction block inside the passenger compartment. If your engine cranks but won't start, and you don't hear the fuel pump hum for about one second when you turn the key to the "Run" position, the relay or the fuel pump itself may be faulty.

Understanding the 2002 Chrysler Sebring Fuel System

The 2002 Chrysler Sebring came in several body styles, and the fuel system layout differs slightly between the sedan and coupe versions. The sedan uses a 2.4L four-cylinder or 2.7L V6 engine, while the coupe uses a 2.4L or 3.0L V6 engine. Regardless of the engine, the fuel pump relay is responsible for sending power to the fuel pump when you turn the ignition key. The fuel pump pressurizes the fuel system, and without it, the engine won't start.

A common symptom of a bad fuel pump relay is that the engine cranks but does not start, and you cannot hear the fuel pump humming from the rear of the car when you first turn the key. The fuel pump should run for about one second to prime the system. If it doesn't, the relay, the fuel pump, or the power supply could be the problem.

Where Is the Fuel Pump Relay on a 2002 Chrysler Sebring Sedan?

For the 2002 Chrysler Sebring sedan (built on the JR platform), the fuel pump relay is located in the underhood power distribution center. This black plastic box is situated near the air cleaner assembly on the driver's side of the engine compartment.

To access the relay:

  1. Open the hood and locate the power distribution center. It is a rectangular black box with a removable cover.
  2. Remove the cover by pressing the release tabs. On the underside of the cover, you will find a diagram showing the fuse and relay layout.
  3. Look for the relay labeled "Fuel Pump Relay." In the sedan diagram, the fuel pump relay is typically labeled as R10 or R3, depending on the specific fuse box revision.
  4. The relay is a small, square plastic component that plugs into the fuse box. You can gently pull it straight up from its socket.

For the 2002 Chrysler Sebring sedan, the fuel pump relay is located at the R10 position in the underhood fuse box according to many fuse box diagrams. Some earlier diagrams show it as R3. The best way to confirm is to check the diagram on the underside of your fuse box cover.

Where Is the Fuel Pump Relay on a 2002 Chrysler Sebring Coupe?

The 2002 Chrysler Sebring coupe has a different layout. The fuel pump relay for the coupe is located on the junction block inside the passenger compartment. The junction block is positioned on the left end of the dashboard, behind a plastic end cover.

To access it:

  1. Open the driver's side door and look at the left end of the dashboard.
  2. Pull the plastic end cover straight out to remove it. This reveals the fuse and relay panel.
  3. Find the fuel pump relay. On the coupe, the fuel pump relay is typically labeled on the back of the cover or in the owner's manual.

For the 2002 Chrysler Sebring coupe with the 3.0L V6 engine, the fuel pump relay is the in-board-most of the three relays on the firewall in front of the driver. This is a different location than the sedan, so it is important to know which body style you have.

How to Test the Fuel Pump Relay

Before replacing the relay, you can test it to confirm it is the problem. Here is a simple way to check:

Step 1: Listen for the Fuel Pump
Turn the ignition key to the "Run" position (do not crank the engine). Listen carefully from the rear of the car. You should hear a brief humming sound from the fuel pump that lasts about one second. If you hear it, the relay and the pump are working. If you do not hear it, the relay or the pump may be faulty.

Step 2: Check for Power at the Relay
Remove the fuel pump relay from the fuse box. Use a test light or a multimeter to check if there is power at the relay socket terminals. With the ignition in the "Run" position, you should see battery voltage on one or more terminals. If there is no power, the fuse or wiring may be the problem.

Step 3: Bypass the Relay (Jumper Wire Test)
If you want to bypass the relay to test the fuel pump directly, you can use a jumper wire. For the sedan, connect a jumper wire between female terminals 16 and 15 of the fuel pump relay socket in the underhood fuse box. For the coupe, jump a wire from the red/brown wire to the black/blue wire at the relay socket. This will turn on the fuel pump directly. If the pump runs, the relay is bad. If the pump does not run, the fuel pump itself or the wiring is likely the problem.

Important: Do not drive the vehicle with the relay bypassed, as the fuel pump will run continuously even if the engine stalls or you are in an accident. This is for testing only.

Common Symptoms of a Bad Fuel Pump Relay

If the fuel pump relay fails, you may experience one or more of these symptoms:

1. Engine Cranks But Does Not Start
This is the most common symptom. The engine turns over but will not fire because there is no fuel pressure.

2. No Fuel Pump Noise
When you turn the key to "Run," you should hear a brief humming sound from the fuel pump. If you hear nothing, the relay is not sending power to the pump.

3. Engine Starts Then Stalls
A failing relay may work intermittently, allowing the engine to start but then stall when the relay loses contact.

4. Erratic Idling or Stalling While Driving
If the relay is failing, it may cut power to the fuel pump while driving, causing the engine to stall suddenly.

How to Test Fuel Pressure on a 2002 Chrysler Sebring

If the relay is working but the engine still won't start, you should test the fuel pressure. The correct fuel pressure for a 2002 Chrysler Sebring is 53-63 PSI with the key on, engine off (KOEO). This applies to both the 2.4L four-cylinder and the 2.7L V6 engines.

To test fuel pressure:

  1. Relieve the fuel system pressure by removing the fuel pump relay and cranking the engine until it stalls.
  2. Disconnect the fuel inlet line from the fuel injector rail. Wrap a shop towel around the line to catch any fuel spillage.
  3. Connect a fuel pressure gauge adapter between the fuel line and the fuel injector rail.
  4. Reactivate the fuel pump by bypassing the relay (jumper terminals 16 and 15 in the relay socket) or by reinstalling the relay and turning the key to "Run."
  5. Read the pressure gauge. It should be between 53 and 63 PSI.

What the results mean:

  • 0 PSI: The fuel pump is not delivering fuel. It is likely bad and needs replacement.
  • Below 53 PSI but not zero: The fuel pump is failing. It may still run but does not provide enough pressure for the engine to run properly. You may experience stalling, loss of power, or lean air/fuel mixture trouble codes.
  • Within 53-63 PSI: The fuel pump and relay are working correctly. The problem is elsewhere, such as the ignition system, sensors, or other components.

Where to Find the Fuse for the Fuel Pump

The fuel pump relay is also protected by a fuse. For the 2002 Chrysler Sebring sedan, the fuse for the fuel pump is located in the underhood fuse box. The fuel pump is powered through fuse #8 (Start/Fuel 20A) or fuse #14 (PCM/ASD 30A), depending on the specific wiring diagram. For the coupe, the fuel pump fuse is #24 (Fuel Pump 15A) in the underhood fuse box.

Check these fuses if the relay is not getting power. A blown fuse will prevent the relay from operating.

How to Replace the Fuel Pump Relay

Replacing the fuel pump relay is a simple job that takes about five minutes.

Step 1: Locate the relay as described above.
Step 2: Pull the relay straight up from its socket. It may require a firm tug.
Step 3: Insert the new relay. Make sure it is oriented the same way as the old one. Most relays have a notch or a diagram on the top to indicate the correct orientation.
Step 4: Push the relay down firmly until it clicks into place.
Step 5: Test the system by turning the key to "Run" and listening for the fuel pump.

What If the Relay Is Not the Problem?

If the relay is good and the fuse is not blown, the problem may be with the fuel pump itself, the wiring, or the engine control module. The fuel pump is located inside the fuel tank, and it may need to be tested with a fuel pressure gauge as described above. If the pressure is zero, the pump is likely bad and needs to be replaced.

The fuel pump on a 2002 Chrysler Sebring is accessed by removing the fuel tank. Some models have an access panel under the rear seat, but on most Sebring models, you must drop the fuel tank to replace the pump. This is a more involved job that requires draining the fuel tank and disconnecting the fuel lines and electrical connectors.

When to Call a Professional

If you have tested the relay, the fuse, and the fuel pressure, and you still cannot find the problem, it may be time to consult a professional mechanic. The issue could be a faulty crankshaft or camshaft position sensor, a bad engine control module, or a wiring problem. A professional scan tool can read fault codes from the engine computer, which can help pinpoint the problem quickly.
