The fuel injector in a 2005 Pontiac Grand Am is located in the engine's intake manifold or cylinders, as part of the fuel and engine management system. The fuel injector controls the way that fuel is delivered to the engine, spraying it into the engine at regular intervals. The fuel travels from the tank into the fuel injectors via a fuel pump. If the injectors are clogged or damaged, the fuel won't reach the engine as it should.

What You'll Learn
The fuel injector is located near the fuel tank
To access the fuel injector, you will need to raise and support the vehicle and perform several disconnecting procedures. Firstly, disconnect the quick-connect fitting at the fuel filter and the quick-connect fittings at the end of the fuel lines. Remove the rubber exhaust hangers, allowing the exhaust system to rest on the rear axle. Remove the exhaust heat shield, and loosen the fuel filler hose clamp near the fuel tank.
Once these initial steps are completed, you can proceed to remove the hoses from the fuel tank filler, the EVAP vent, and the EVAP vapor pipes. It is important to have an assistant to support the fuel tank during this process. Disconnect the electrical harness from the multi-way rear body connector and the fuel strap.
After ensuring the fuel tank is supported, you can carefully lift the fuel injector and begin the replacement process. This typically involves prying up the fuel injector with a pry bar and lifting it out. It is important to note that you should always replace the fuel filter when replacing the fuel injector. Additionally, you may need to apply white grease around the edges of the new fuel injector and push the leads back into place, ensuring they are in the correct order.

The fuel pump relay is located in the engine compartment fuse box
The fuel injector in a 2005 Pontiac Grand Am is part of the fuel and engine management system. It atomizes fuel into the engine's intake manifold or cylinders. The fuel travels from the tank into the fuel injectors by way of a fuel pump. The injectors then spray the fuel into the engine at regular intervals.
If you are having trouble with your fuel pump, you may need to check the fuse box under the hood. The fuel pump relay is located in the engine compartment fuse box. The cover should be easy to remove, and the fuel pump should be connected through a fuse in slot 48. If that fuse looks good, you may want to check the fuel pump relay (also inside the engine compartment fuse box). The fuel pump relay is #18 in the fuse box. Start with the car off, and have someone else put the key in the car's ignition and attempt to start the car while you listen to the relay. If you can hear this relay make a "clicking" noise as the car attempts to start, then it is working properly.
If you are still having trouble with your fuel pump, there are many reasons your car may not start. Anything from a factory security system locking you out, a bad fuse or relay, a clogged fuel filter, a faulty fuel pump, oil sending unit/crank sensor failure, a clogged catalytic converter, failing electronic ignition, or ECM/PCM issues. As a first step, it is best to see if there are any stored trouble codes that could point directly to the fault. Some auto parts suppliers offer free code reading, and their staff may be knowledgeable about the issue.

The fuel filter should be replaced when replacing the fuel injector
The fuel injector in a 2005 Pontiac Grand Am is located in the engine. The injectors spray fuel into the engine at regular intervals. If the injectors are clogged or damaged, the fuel isn't getting into the engine as it should, which can cause poor engine performance and fuel economy.
When replacing the fuel injector, it is recommended to replace the fuel filter as well. This is because the fuel filter can become clogged with crud or dissolved residue, which can then affect the performance of new injectors.
To replace the fuel filter, first relieve the fuel system pressure and raise and support the vehicle. Disconnect the quick-connect fitting at the fuel filter and the fittings at the end of the fuel lines. Remove the rubber exhaust hangers and allow the exhaust system to rest on the rear axle. Remove the exhaust heat shield and loosen the fuel filler hose clamp at the fuel tank. Disconnect the electrical harness from the rear body connector and fuel strap. With an assistant, support the fuel tank and disconnect the fuel tank retaining straps. Lower the fuel tank and disconnect the wiring harness from the modular fuel sender assembly and the fuel tank pressure sensor.
Finally, disconnect the EVAP and fuel pipes from the modular fuel sender and the fill limiter vent valve. Install the new fuel filter by following these steps in reverse. It might be a good idea to ''prime'' the new fuel filter with BG-44K prior to installation.

The fuel injector can be accessed by removing the rear seat
The fuel injector in a 2005 Grand Am can be accessed by removing the rear seat. This process is relatively straightforward and can be completed in a few steps.
First, fold down the trap in the middle of the rear seat to access the trunk. Once inside the trunk, lift the carpet to reveal the fuel tank cover. You will then need to disconnect the two electrical connections and the three tubes connected to the fuel sending unit.
At this point, you will need to remove the fuel sender assembly from the tank. This involves loosening a metal ring locking mechanism and turning a large knob to release it. Be careful, as approximately half a cup of gas will be released during this step.
With the fuel sender assembly removed, you will have access to the fuel injectors. To replace a fuel injector, simply lift it out and install a new one in its place. Be sure to apply a small amount of white grease around the edges of the new fuel injector before putting the fuel injector leads back into place.
It is important to note that this process may vary slightly depending on the specific make and model of your Grand Am. Additionally, working with fuel and vehicle components can be dangerous, so it is always recommended to consult a professional or a repair manual for detailed instructions before attempting any repairs or maintenance.

The fuel injector can be replaced using common tools
The fuel injector on a 2005 Pontiac Grand Am is located near the engine. It can be replaced using common tools, and the procedure is the same for most GM cars with a 3.4-liter V6 engine. The tools you'll need include a 10mm and 13mm socket and ratchet, a flat-blade screwdriver, a Phillips screwdriver, a pair of pliers, a drip pan, a funnel with a screen or filter, a vacuum, a pry bar, and some white grease.
First, unplug each of the spark plug wires, being sure to remember their order. Then, loosen the hose clamp and drain the coolant. Lift up and remove the hoses, and then remove the gaskets. Disconnect the connector and remove the two 10mm bolts. Vacuum out the top of the engine to get rid of any dirt and buildup. Using a pry bar, carefully pry up the fuel injectors and lift them out.
With the fuel rail up, pull out the metal clip above the fuel injector and move the fuel injector back and forth to pull it free. If the O-ring stays inside, use a small flat-blade screwdriver to pull it back out and put it back on the fuel injector. Push the new fuel injector into place, replace the clip, and apply a small amount of white grease around the edges. Put the fuel injector leads back into place, making sure they are in the correct order. Finally, line up the fuel injectors and push them down into place.
By following these steps and using common tools, you can replace the fuel injector on your 2005 Pontiac Grand Am.
