Here's a general overview of the process. This is not a complete, step-by-step guide and should not be considered a substitute for a professional repair manual specific to your 1989 Ford Taurus. Consult a repair manual for detailed instructions and diagrams specific to your vehicle's year and engine.
Tools You'll Likely Need:
* Socket set (metric)
* Wrenches (metric)
* Screwdrivers (Phillips and flathead)
* Fuel pump pliers or a fuel line disconnect tool
* Safety glasses
* Gloves
* Jack and jack stands
* Wheel chocks
* Fuel line clamps
* New fuel pump (ensure it's the correct one for your vehicle)
* New fuel filter (recommended)
* Shop rags
* Container to catch fuel
* Torque wrench (recommended)
General Steps:
1. Safety First: Disconnect the negative battery terminal.
2. Prepare the Vehicle: Raise and securely support the vehicle on jack stands. Place wheel chocks on the wheels that remain on the ground.
3. Access the Fuel Pump: This usually involves lowering the fuel tank. The specific method varies depending on the Taurus model (sedan, wagon). This often requires removing the access panel under the car and possibly detaching the fuel filler neck and lines. You'll need to consult your repair manual for the exact procedure. This is often the most challenging part of the job.
4. Disconnect Fuel Lines: Once access is gained, carefully disconnect the fuel lines from the fuel pump. Use fuel line pliers or disconnect tools to prevent damage to the lines. Have rags ready to soak up any spilled fuel. Important: Note which line goes where to avoid problems during reassembly.
5. Disconnect Electrical Connector: Disconnect the electrical connector from the fuel pump.
6. Remove the Fuel Pump Assembly: This is usually held in place by a retaining ring or bolts. The fuel pump might be integrated into a module that needs to be removed as a unit. Your repair manual will provide details specific to your model.
7. Install the New Fuel Pump: Carefully install the new fuel pump assembly, ensuring all seals and gaskets are properly seated.
8. Reconnect Everything: Reconnect the electrical connector and fuel lines, ensuring a tight and secure connection. Use new clamps if necessary.
9. Lower the Fuel Tank: Carefully lower the fuel tank back into its position.
10. Reconnect the Fuel Filler Neck and Lines: Reconnect any components that were disconnected to access the fuel pump.
11. Lower the Vehicle: Carefully lower the vehicle to the ground.
12. Reconnect the Battery: Reconnect the negative battery terminal.
13. Prime the Fuel System: You might need to prime the fuel system by turning the ignition key on and off several times before attempting to start the engine. Consult your repair manual for details on this step.
14. Test the Fuel System: Start the engine and check for leaks around the fuel lines and pump assembly. Let the engine run for a few minutes to ensure it's running smoothly.
Important Considerations:
* Fuel Pressure: Be aware that there is residual pressure in the fuel system. Releasing this pressure incorrectly can be dangerous.
* Safety: Work in a well-ventilated area due to fuel fumes.
* Repair Manual: A factory repair manual for your specific 1989 Ford Taurus model is highly recommended. It will provide detailed diagrams and instructions, ensuring a safe and successful repair.
This is a complex repair and could easily go wrong if not done correctly. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Replacing a fuel pump incorrectly can cause significant damage to your vehicle or result in a fire.
