Here's a general overview. Specific steps and tools may vary slightly depending on the engine (2.0L or 2.5L). Always consult a repair manual specific to your vehicle's year and engine for detailed instructions and diagrams. A Haynes or Chilton manual would be invaluable.
1. Preparation:
* Safety First: Work in a well-ventilated area. Use proper eye protection and gloves. Have a fire extinguisher nearby.
* Tools: You'll need various tools, including sockets (metric), wrenches, screwdrivers (Phillips and flathead), a fuel pump pliers or fuel line disconnect tool, a fuel pump removal tool (possibly), jack and jack stands, possibly a fuel pressure gauge (to ensure the system is properly depressurized after disconnecting the battery), and possibly a torque wrench.
* Gather Parts: Obtain a new fuel pump assembly (including the filter and gasket). Consider replacing the fuel filter at the same time.
* Drain the Fuel Tank (Optional but Recommended): This reduces the risk of spillage and makes the job cleaner. Siphon the gas out using a siphon pump.
2. Access the Fuel Pump:
* Lower the Fuel Tank: This is typically the most challenging part. You'll likely need to:
* Raise the vehicle: Securely lift the car using a jack and jack stands.
* Remove components: This may involve removing the rear seat bottom (or parts of it), detaching the fuel filler neck, disconnecting various electrical connectors and fuel lines. Consult your repair manual for exact steps, as they can vary significantly. You may need to lower the tank straps or possibly even disconnect the exhaust system in certain areas.
* Support the fuel tank: Use a fuel tank support strap or other secure method to support the tank while it's partially lowered. The tank is heavy!
3. Replace the Fuel Pump:
* Disconnect fuel lines: Use the fuel line disconnect tool to safely disconnect the fuel lines from the fuel pump module. Be prepared for some fuel spillage. Have rags ready to absorb any fuel.
* Disconnect electrical connectors: Carefully disconnect the electrical connectors from the fuel pump module.
* Remove the fuel pump assembly: Use a fuel pump removal tool (often specific to the vehicle) to remove the fuel pump assembly from the tank. Some vehicles have a retainer ring to remove.
* Install the new fuel pump: Carefully install the new fuel pump assembly, ensuring the gasket is properly seated.
* Reconnect electrical connectors and fuel lines: Carefully reconnect all electrical connectors and fuel lines. Ensure a tight, secure connection.
* Reinstall the fuel pump assembly: Securely reinstall the fuel pump assembly into the tank.
4. Reassembly:
* Raise the fuel tank: Carefully raise the fuel tank back into its position.
* Reconnect all components: Reconnect all components that were disconnected earlier (fuel filler neck, electrical connectors, etc.).
* Lower the vehicle: Carefully lower the vehicle from the jack stands.
* Reconnect the battery: Reconnect the negative battery cable.
* Prime the fuel system: Some vehicles require you to prime the fuel system after replacing the pump. Check your vehicle's repair manual for instructions. You might need to turn the ignition key on and off several times before starting the engine.
5. Test:
* Start the engine: Check for leaks around the fuel lines and connections.
* Test drive: Take the vehicle for a short test drive to ensure the fuel pump is working correctly and there are no issues.
Important Considerations:
* Fuel pressure: Before disconnecting fuel lines, it's highly recommended to relieve fuel pressure. Consult your repair manual for the specific procedure.
* Static electricity: Be aware of static electricity, which can ignite fuel vapors. Take appropriate precautions.
* Repair manual: This is crucial. Generic instructions cannot cover all possible variations.
* Professional help: If you are not comfortable performing this task yourself, take your vehicle to a qualified mechanic. This is a complex repair with potential safety hazards.
This is a simplified overview. Refer to a repair manual specific to your 1998 Chrysler Sebring LXi for detailed, step-by-step instructions and diagrams. Attempting this repair without proper knowledge and tools can lead to damage to your vehicle and potential injury.
