Here's a general outline of the process. This is not a complete, step-by-step guide. Consult a repair manual specific to your 1996 Pontiac Trans Am for detailed instructions and diagrams. Repair manuals can be found online or at auto parts stores.
1. Safety Precautions:
* Disconnect the negative battery terminal. This is crucial to prevent sparks and electrical shock.
* Work in a well-ventilated area. Gasoline fumes are highly flammable and dangerous.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
* Use jack stands. Never work under a car supported only by a jack.
2. Preparation:
* Locate the fuel pump access panel. This is usually located in the trunk, under the rear seat, or in the underbody. Consult your repair manual for the exact location. You may need to remove interior trim panels to access it.
* Gather your tools: This will likely include various sockets, wrenches, screwdrivers, a fuel pump removal tool (often a specialized socket), pliers, a fuel line disconnect tool, rags, and possibly a fuel pressure gauge.
3. Fuel System Depressurization:
* This is extremely important. You need to relieve pressure in the fuel system before disconnecting any fuel lines. Consult your repair manual for the specific procedure for your vehicle. This might involve starting the engine and letting it run until it stalls after disconnecting the fuel pump relay (this is safer than simply releasing pressure via the schrader valve).
4. Accessing the Fuel Pump:
* Remove the access panel.
* Disconnect the electrical connector to the fuel pump.
* Disconnect the fuel lines. Use the correct fuel line disconnect tool to avoid damaging the lines. Have rags ready to absorb any spilled fuel.
* Remove the fuel pump retaining ring or bolts. This might require a specialized tool.
* Carefully remove the fuel pump assembly from the tank. This assembly will likely include the fuel pump, fuel level sender, and other components.
5. Fuel Pump Replacement:
* Inspect the fuel tank and fuel pump assembly for any damage.
* Install the new fuel pump assembly. Ensure it's properly seated and all components are connected correctly.
* Reconnect the fuel lines and electrical connector.
* Reinstall the retaining ring or bolts.
* Reinstall the access panel.
6. Fuel System Re-pressurization and Testing:
* Reconnect the negative battery terminal.
* Check for fuel leaks.
* Start the engine and let it run for a few minutes to check for proper operation.
* Have the fuel system pressure tested if possible to verify correct operation. This often requires specialized equipment.
