Here's a general overview. This is not a comprehensive guide, and you should consult a repair manual specific to your 2001 Oldsmobile Intrigue before attempting this repair. Repair manuals provide detailed instructions, diagrams, and torque specifications crucial for success.
Safety Precautions:
* Disconnect the negative battery terminal before starting any work.
* Work in a well-ventilated area. Gasoline fumes are dangerous.
* Have a fire extinguisher nearby.
* Wear safety glasses and gloves.
* Use appropriate tools and follow all safety guidelines.
* Properly dispose of old fuel and fuel pump components.
General Steps (Consult your repair manual for specifics):
1. Vehicle Preparation: Secure the vehicle on a level surface. Engage the parking brake.
2. Access the Fuel Pump: This usually involves dropping the fuel tank. The process varies depending on the Intrigue's model and trim. You may need to remove the rear seat(s), access panels under the vehicle, or even detach the exhaust system to gain sufficient access. Consult your repair manual for the specific procedure.
3. Drain the Fuel Tank (Partially or Completely): This reduces the risk of fuel spillage and makes the tank lighter to handle. Use a siphon pump to drain fuel into an approved fuel container.
4. Disconnect the Fuel Lines: Carefully disconnect the fuel lines leading to and from the fuel pump. Have rags ready to absorb any spilled fuel. You will likely need to use line wrenches or fuel line disconnect tools. Mark the lines so you know how to reassemble them.
5. Disconnect the Electrical Connector: Unplug the electrical connector to the fuel pump.
6. Remove the Fuel Pump Assembly: The fuel pump assembly is typically held in place by a retaining ring or bolts. Remove these fasteners to access and remove the assembly. This often involves working through an access hole in the top of the fuel tank.
7. Replace the Fuel Pump: Install the new fuel pump, ensuring it's properly seated and aligned.
8. Reassemble: Reinstall the retaining ring or bolts, reconnect the electrical connector, and reconnect the fuel lines. Ensure all connections are secure and tight.
9. Refuel and Test: Lower the fuel tank, reconnect any components you removed, and carefully refuel the vehicle. Start the engine and check for leaks. Monitor the fuel gauge and operation of the vehicle for a while to ensure the new pump is working correctly.
Important Considerations:
* Fuel Pressure Regulator: The fuel pressure regulator might be integrated into the fuel pump assembly; replace it if necessary.
* Fuel Filter: This is a good opportunity to replace the fuel filter as well, while you're working on the fuel system.
* Tank Straps and Sending Unit: Be careful when handling the fuel tank; it is heavy and potentially dangerous. Pay attention to the tank straps and fuel level sending unit, if applicable, ensuring they are properly reinstalled.
* Fuel Pump Compatibility: Ensure the replacement fuel pump is the correct one for your vehicle's specifications.
This is a complex repair. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Improper installation can lead to serious problems, including engine damage or fire. Again, always consult your repair manual for detailed instructions specific to your vehicle.
