Here's a general outline. Specific details may vary slightly depending on the engine (2.0L, 2.5L, 2.8L V6). Consult a repair manual specific to your 1986 Chevy Celebrity and engine for precise instructions and torque specifications. This is crucial to avoid damage.
Tools you'll likely need:
* Socket set (metric)
* Wrenches (metric)
* Screwdrivers (Phillips and flathead)
* Fuel line disconnect tool (or pliers, but the tool is recommended to avoid damage)
* Jack and jack stands (or ramps)
* Fuel pump pliers (for clamping the fuel lines)
* New fuel pump assembly (ensure it's the correct one for your car)
* Safety glasses
* Gloves
* Rags or shop towels
* Drain pan
* Fuel pressure gauge (optional, but recommended to verify pressure after installation)
Steps (General Outline):
1. Safety First: Disconnect the negative battery cable.
2. Access the Fuel Pump: The fuel pump is typically located inside the fuel tank. This usually involves:
* Lowering the fuel tank: This is often the most challenging part. You'll need to support the tank safely. You may need to disconnect various components connected to the tank (fuel lines, electrical connectors, etc.). Consult your repair manual for the precise procedure. Be aware that some fuel might remain in the tank, so be prepared.
* Alternatively, some models may allow access through a dedicated access panel in the trunk or under the rear seat. Check your repair manual.
3. Disconnect Fuel Lines: Use fuel line disconnect tools to carefully disconnect the fuel lines from the pump. Have rags ready to absorb any spilled fuel.
4. Disconnect Electrical Connections: Carefully disconnect the electrical connectors from the fuel pump.
5. Remove the Fuel Pump: Once the lines and electrical connections are disconnected, you should be able to remove the fuel pump assembly from the tank. This often involves removing retaining clips or bolts.
6. Install the New Fuel Pump: Carefully install the new fuel pump assembly, ensuring it's properly seated.
7. Reconnect Everything: Re-connect the fuel lines, electrical connectors, and any other components you disconnected.
8. Raise the Fuel Tank (if lowered): Carefully raise the fuel tank back into its original position.
9. Reconnect the Battery: Connect the negative battery cable.
10. Prime the Fuel System: This is essential. You may need to turn the ignition key to the "ON" position (without starting the engine) several times to prime the fuel pump and fill the lines.
11. Check for Leaks: Carefully inspect all connections for leaks.
12. Test the Vehicle: Start the engine and check for proper operation. Listen for unusual noises from the fuel pump. Use a fuel pressure gauge to check the fuel pressure if you have one.
Important Considerations:
* Fuel Pressure: The fuel system is under pressure. Releasing this pressure improperly can be dangerous. Your repair manual should provide instructions on how to safely relieve fuel pressure.
* Fuel Tank Safety: The fuel tank can be heavy. Take precautions to avoid injury while handling it.
* Repair Manual: This is absolutely essential. Do not attempt this repair without a repair manual specific to your 1986 Chevy Celebrity and engine.
This is a simplified overview. Refer to a repair manual for detailed, step-by-step instructions, diagrams, and torque specifications. If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improperly installing a fuel pump can lead to serious safety hazards.
