Here's a general outline. Specific steps might vary slightly depending on the exact model and engine of your Camry (2.0L or 2.5L). Always consult a repair manual specific to your 1989 Toyota Camry for detailed instructions and diagrams.
1. Safety First:
* Disconnect the negative battery terminal. This is paramount to prevent sparks.
* Ventilate the area. Work in a well-ventilated space to dissipate any fuel fumes.
* Wear safety glasses and gloves. Protect yourself from potential fuel spills and sharp objects.
* Have a fire extinguisher readily available.
2. Preparation:
* Locate the fuel pump. It's usually located inside the fuel tank, requiring tank removal or access through a dedicated access panel. Your repair manual will show its precise location.
* Gather necessary tools. You'll need various sockets, wrenches (possibly a fuel line disconnect tool), screwdrivers, jack stands, jack, and possibly a fuel pump removal tool. A torque wrench is also highly recommended.
* Drain the fuel tank. This is highly recommended to reduce the amount of fuel you have to deal with. Siphon the fuel into a properly labeled and sealed container.
3. Fuel Tank Access:
* Secure the vehicle. Use jack stands to safely support the vehicle after raising it with a jack. Never work under a vehicle supported only by a jack.
* Access the fuel tank. This usually involves lowering the fuel tank. Consult your repair manual for the specific procedure; it might involve removing the rear seat, disconnecting fuel lines, electrical connectors, and possibly detaching the fuel tank straps.
4. Fuel Pump Removal:
* Disconnect the fuel lines. Be prepared for some fuel spillage. Use rags to soak up any leaks. A fuel line disconnect tool will help prevent damage.
* Disconnect the electrical connector.
* Remove the fuel pump access plate (if applicable).
* Remove the fuel pump assembly. This may involve using a special tool or carefully working it out.
* Inspect the fuel pump and surrounding components. Check for wear, debris, or damage.
5. Fuel Pump Installation:
* Install the new fuel pump assembly. Make sure the o-rings and gaskets are properly seated.
* Reconnect the electrical connector.
* Reconnect the fuel lines. Tighten connections securely.
* Replace the access plate (if applicable).
* Reinstall the fuel tank.
6. Post-Installation:
* Lower the vehicle carefully.
* Reconnect the negative battery terminal.
* Check for leaks. Inspect all fuel lines and connections carefully.
* Prime the fuel system. This may involve turning the ignition key to the "on" position (without starting the engine) several times to build pressure.
* Start the engine and check for proper operation. Listen for any unusual noises and monitor the fuel gauge.
