What You'll Learn
Removing the fuel pump fuse
To remove the fuel pump fuse of a 2007 Grand Prix, you must first locate the fuse box. For the 2007 model, the fuse box is located under the hood, unlike some earlier models where it can be accessed from the back seat.
Once you have located the fuse box, you will need to identify the fuel pump fuse. This should be marked clearly and located next to the relay. The relay is a small, usually black, component with wires coming out of it.
With the fuel pump fuse located, you can now remove it. To do this, simply pull the fuse out of its socket. In some cases, you may need to use a small tool, such as a screwdriver, to gently pry it out. Be careful not to damage the fuse or the fuse box.
It is important to note that removing the fuel pump fuse will disable the fuel pump, preventing it from receiving power. This means that the engine will not be able to draw fuel from the tank, and the car will not start or run. Make sure you have a safe and appropriate place to work on your vehicle before proceeding.
Additionally, always exercise extreme caution when working with the fuel system. Ensure the engine is off and the keys are removed from the ignition to prevent any accidental startups.

Using the trunk access panel
To remove the fuel tank from a 2007 Grand Prix using the trunk access panel, follow these steps:
First, relieve the fuel system pressure and drain the fuel tank until it is about one-quarter full. You can do this by starting the car and pulling the pump fuse, which is located in the box under the hood. When the car dies, the pressure will be released.
Next, disconnect the negative battery terminal with a socket wrench. Clear the trunk by removing the jack and spare tire. Then, remove the trunk lining and fold down the trap in the middle of the rear seat to access the trunk.
Now, you should be able to see the fuel tank cover. Lift the carpet inside the trunk to see it. Disconnect the electrical connections and the three tubes connected to the fuel sending unit. Some fuel may spill out, so it is recommended to have some towels ready to absorb it.
Once the connections are disconnected, remove the metal holding piece. The canister will then be ready to come out, but you will need to twist it to get it out.
Finally, with the aid of an assistant, support the fuel tank and disconnect the two fuel tank retaining straps. Lower the fuel tank and disconnect any remaining hoses and pipes.

Dropping the fuel tank
To remove the fuel tank from a 2007 Grand Prix, you will first need to locate the fuel pump fuse and remove it. This will allow the car to suck out all the fuel in the lines, so you won't need to worry about any fuel leaking out while you work.
Next, you will need to locate the fuel pump. On some models, there is an access panel in the trunk that will allow you to reach the fuel pump without dropping the tank. This access panel is usually under the carpet, right behind the fold-down access in the rear seat. However, some people have claimed that there is no trunk access on the Grand Prix, so you may need to consult a mechanic or a dealer to confirm the location of the fuel pump in your specific model.
If there is no trunk access, you will need to drop the fuel tank in order to reach the fuel pump. This is a more complicated process and may require the assistance of a professional. Be sure to take all necessary safety precautions when working with fuel and electricity.
Once you have accessed the fuel pump, you can begin the process of removing and replacing it. Again, if you are unsure about any part of this process, it is always best to consult a professional.
Finally, after you have replaced the fuel pump, you can put the fuel tank back into place and re-install the fuel pump fuse. Be sure to follow all manufacturer instructions and safety guidelines when working on your vehicle.

Replacing the fuel pump
To replace the fuel pump of a 2007 Grand Prix, you may need to remove the fuel tank. However, some sources suggest that there is an access panel in the trunk that allows you to replace the fuel pump without removing the tank. Here is a step-by-step guide on how to replace the fuel pump:
First, locate the access panel in the trunk. Open the pass-through hatch in the rear seat and pull up the carpeting. You should see a 6-8" panel with about eight screws around it. This is the access panel for the fuel pump.
Once you have located the access panel, remove the screws and carefully open the panel. With the panel open, you should be able to see the fuel pump. Twist the fuel pump to remove it from the tank. Install the new fuel pump by twisting it into place and securing it with the screws.
If you are unable to locate the access panel or if your vehicle does not have one, you may need to remove the fuel tank to replace the fuel pump. This is a more involved process and may require additional tools and safety precautions.
Before beginning any work, ensure that you have depressurized the fuel line and that there is no fuel remaining in the lines. This can be done by removing the fuel pump fuse or loosening a fitting at the filter side to relieve the pressure. Always exercise extreme caution when working with flammable liquids and gases.
When removing the fuel tank, be sure to follow the appropriate safety procedures and have the necessary tools and equipment. It may be necessary to raise the vehicle and support it securely on jack stands to access the fuel tank from underneath. Once the fuel tank is removed, you can replace the fuel pump and reinstall the tank.
Finally, always refer to the vehicle's service manual for specific instructions and safety information pertaining to your particular model. Replacing a fuel pump can be a complex task, and it is important to ensure that the job is done safely and correctly.

Cleaning the fuel filter
To clean the fuel filter of a 2007 Grand Prix, you must first locate it. According to some sources, it is under the car on the driver's side, just ahead of the rear wheel. However, one source states that it is underneath the driver's side of the car towards the rear.
Once you have located the fuel filter, you can begin the cleaning process. Here is a step-by-step guide:
- De-pressurize the fuel line to prevent gas from shooting out and covering your face.
- Remove the cover from the housing of the fuses and relays, and locate the fuel pump relay.
- Unscrew the fuel line from the filter. Some gas will come out, so use a drip pan to catch it and protect yourself.
- Remove the old fuel filter by pushing in the tabs on the plastic piece and pulling the filter off.
- Clean the gas off the two fuel lines with a rag.
- Install the new fuel filter by pushing the fuel line onto the filter end until you hear a small click.
- Attach the brace to the new filter and screw the bolt back in.
- Reinsert the relay for the fuel pump and close the housing.
- Get into the driver's seat and turn the key on, but do not start the engine. This will re-pressurize the fuel line.
- Check for leaks at both ends of the fuel filter.
- If no leaks are present, turn on the engine. It may stutter as fuel re-enters the engine, so let it idle for a few seconds.
By following these steps, you can effectively clean and replace the fuel filter on your 2007 Grand Prix.
