Here's a general outline; however, you MUST consult a repair manual specific to your 1999 Oldsmobile Intrigue for detailed instructions, torque specifications, and safety warnings. The repair manual will show you the exact location of components and provide diagrams.
Safety First!
* Disconnect the negative battery terminal before starting any work. This prevents accidental sparks that could ignite fuel vapors.
* Work in a well-ventilated area. Fuel vapors are highly flammable.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
General Steps (Consult your repair manual for specifics):
1. Vehicle Preparation: Raise the vehicle securely using jack stands. Locate the fuel pump access panel, usually under the rear seat or in the trunk. This may involve removing interior trim panels.
2. Fuel System Depressurization: You need to relieve pressure from the fuel system. The exact procedure varies but may involve starting the engine and letting it run until it stalls (after disconnecting the fuel pump relay), or using a fuel pressure gauge and release valve. Consult your repair manual.
3. Access the Fuel Pump: Remove the access panel to expose the fuel pump assembly. This often involves removing the fuel tank retaining straps or other components. You may need to disconnect electrical connectors and fuel lines.
4. Fuel Pump Removal: Carefully remove the fuel pump assembly from the tank. This usually involves unscrewing a retaining ring or other fastening mechanism. Be careful not to damage the fuel pump gasket.
5. Installation of the New Fuel Pump: Carefully install the new fuel pump assembly into the tank, ensuring the gasket is properly seated. Secure the retaining ring or other fastening mechanism.
6. Reconnect Fuel Lines and Electrical Connectors: Reconnect the fuel lines and electrical connectors to the new fuel pump, ensuring a tight and secure connection.
7. Reinstallation: Reinstall the access panel, interior trim panels, etc.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Reconnect Battery: Reconnect the negative battery terminal.
10. Prime the Fuel System (If Required): Some systems require priming the fuel pump after installation. Consult your repair manual.
11. Test the Vehicle: Start the engine and check for leaks. Monitor the fuel gauge and drive the vehicle to ensure the fuel pump is functioning correctly.
Important Considerations:
* Fuel pump replacement often requires specialized tools. You may need a fuel pump socket, fuel line disconnect tools, and potentially a fuel pressure gauge.
* The fuel tank may need to be dropped or partially lowered for easier access. This is a more complex procedure.
* Always replace the fuel filter at the same time as the fuel pump.
* Improperly tightening fuel line connections can lead to leaks.
This is a simplified overview. Do not attempt this repair without a detailed repair manual specific to your 1999 Oldsmobile Intrigue. If you are not comfortable performing this repair, it is best to take your vehicle to a qualified mechanic. Improper installation can lead to serious injury or damage to your vehicle.
