Replacing the fuel pump in a 2002 Pontiac Firebird is a complex task that can be made easier with some advanced preparation. The fuel pump is located in the fuel tank, so the first step is to relieve the pressure in the fuel system and drain the gas from the tank. Next, disconnect and remove the fuel tank and sender assembly from the fuel pump. You can then disconnect the fuel sender from the tank and remove the pump. To install the new fuel pump, simply reverse these steps, taking care to plug in the fuel lines and electrical connectors.

What You'll Learn
Remove the fuel tank
To remove the fuel tank from a 2002 Pontiac Firebird, follow these steps:
Park the car on a level surface and engage the parking brake. Loosen the fuel cap to relieve pressure in the tank.
Jack up the rear of the car and secure it with jack stands. Make sure the car is stable and you have enough room to work underneath. Remove the rear wheels.
Locate the fuel tank and identify the fuel lines, electrical connections, and mounting hardware. Disconnect the fuel lines and electrical connectors from the fuel tank. This may involve removing nearby components or covers for access.
Place a drain pan or container underneath the fuel tank to catch any remaining fuel. Slowly lower the fuel tank from the vehicle, being careful not to damage any surrounding components.
Once the fuel tank is removed, you can access the fuel pump for replacement. It is important to work carefully and safely when dealing with flammable liquids and high-pressure fuel systems. If you are unsure about any steps, consult a qualified mechanic.

Next, disconnect the negative battery cable and raise the car on jack stands. Drain the fuel from the tank by removing the tank's drain plug or the line running to the fuel filter. Make sure you know how much fuel is in the tank and have an approved container to pour it into.
Now, you can disconnect and remove the fuel tank and sender assembly from the fuel pump. To do this, first, clean the fuel system's exterior, especially around the fuel-sender assembly.

Cut a trap door
To cut a trap door to change the fuel pump in a 2002 Pontiac Firebird, you will need a flat-head screwdriver and a hammer, rags and cleaning solution, and a Dremel with a cutting wheel.
Before you cut the trap door, some steps need to be taken to allow the fuel pump to be replaced safely and successfully. First, pull the fuel pump fuse and disconnect the negative (black) battery terminal. Also, bleed the fuel pressure at the Schrader valve on the driver's side fuel rail. Make sure you have a bucket and rags ready for this. Lastly, open the gas cap to relieve any more pressure. Now, you can proceed to cut the trap door. Use a Dremel with a cutting wheel and go slowly! Make sure that nothing gets cut that shouldn't be, like wiring harnesses and fuel lines.
Now, you must remove the two connectors on top of the fuel pump assembly. They simply unclip and come off of the fuel pump assembly. Also, clean the area in the trap door carefully to minimize the risk of dirt falling into the tank. Now, the three fuel lines can be disconnected by simply pulling and unclipping them off the plastic hose connectors. Have rags ready to catch any fuel that might come out of these lines. Then, you can use a screwdriver and hammer on the edges of the fuel pump retaining ring to spin it away from the locks to be able to remove the assembly. The fuel pump assembly should easily lift out of the trap door now.
Be careful working in the trap door area, as the edges are sharp!
