Here's a general outline of the process. Specific steps may vary slightly depending on your vehicle's configuration. Always consult a repair manual specific to your 1995 Buick Skylark for precise instructions and diagrams. A Haynes or Chilton manual is a good investment.
1. Preparation:
* Safety First: Disconnect the negative battery terminal. Let the car sit for at least 15 minutes to allow residual pressure in the fuel system to dissipate.
* Gather Tools: You'll need a socket set (metric), wrenches, screwdrivers (possibly including Torx), fuel line disconnect tools, a fuel pump removal tool (often a special socket or strap wrench), jack stands, jack, safety glasses, gloves, and rags. A fuel pressure gauge is helpful but not strictly necessary.
* Locate the Fuel Pump: The fuel pump is typically located inside the fuel tank, requiring tank removal or access from underneath. Consult your repair manual for the exact location and access method.
2. Fuel Tank Access:
* Lower the Fuel Tank: This usually involves lowering the tank from underneath the car. You'll need to support the tank securely with jack stands while you're working on it. Disconnect the fuel lines, electrical connector, and vent line. Be aware that the tank will contain some fuel, so take precautions to prevent spills. Some models may allow tank access through a trap door in the trunk floor.
3. Fuel Pump Removal:
* Disconnect Electrical Connector: Unplug the electrical connector from the fuel pump.
* Disconnect Fuel Lines: Use the correct fuel line disconnect tools to carefully separate the fuel lines from the pump. Have rags ready to absorb any spilled fuel.
* Remove the Fuel Pump: This is usually done by accessing it through the top of the fuel tank after removing the fuel pump access cover. You'll likely need a fuel pump removal tool to secure and unscrew the pump from its retaining ring or cover.
4. Fuel Pump Installation:
* Install New Fuel Pump: Carefully install the new fuel pump, ensuring that all seals and gaskets are properly seated.
* Reconnect Fuel Lines: Reconnect the fuel lines securely.
* Reconnect Electrical Connector: Plug the electrical connector back into the fuel pump.
* Reinstall the Fuel Tank and Components: Reverse the removal process to reinstall the fuel tank, securing all connections.
5. Testing:
* Reconnect Battery: Reconnect the negative battery terminal.
* Check for Leaks: Check carefully for any fuel leaks around the fuel lines and tank connections.
* Start the Engine: Start the engine and let it run for a few minutes to ensure the new fuel pump is functioning correctly. Check for any unusual noises or performance issues.
Important Considerations:
* Fuel Pressure: Some repairs necessitate relieving fuel pressure before working on the system; consult your repair manual.
* Fuel Type: Use the correct type of gasoline for your car.
* Cleanliness: Keep the area clean and free of debris.
* Professional Help: If you're not comfortable performing this repair yourself, take your car to a qualified mechanic. Improperly working on the fuel system can be dangerous.
This is a general guide; always consult a repair manual specific to your 1995 Buick Skylark for detailed instructions and diagrams. Improperly performing this repair could lead to serious injury or damage to your vehicle. If you're unsure about any step, it's best to seek professional help.
