What You'll Learn
The fuel pump is located in the fuel tank
The fuel pump is located underneath the fuel tank cover, and you will see two electrical connections that will need to be disconnected. You will also see three tubes connected to the fuel sending unit. Disconnect these tubes as well, and around half a cup of gas will come out.
To remove the fuel pump, you will need to turn a big knob that is part of a locking disc and metal ring locking the pump in place. This is the hard part, and it may be easier with three tools.
The fuel pump is an essential part of the fuel system, and a faulty fuel pump can cause the car to crank and not start.

The fuel filter can also be accessed from inside the car. To do this, fold down the trap in the middle of the rear seat to access the trunk. Lift the carpet inside the trunk to see the fuel tank cover. Disconnect the electrical connections and the three tubes connected to the fuel sending unit.
Before attempting to replace the fuel filter, it is important to relieve the fuel system pressure and raise and support the vehicle. Disconnect the quick-connect fitting at the fuel filter and the quick-connect fittings at the end of the fuel lines.

To access the fuel filter, you will need to fold down the trap in the middle of the rear seat to access the trunk. Lift the carpet inside the trunk to locate the fuel tank cover. Disconnect the two electrical connections and the three tubes connected to the fuel sending unit.
You will then need to disconnect the fuel lines from the fuel filter. There will be some gas in the lines, so be prepared to catch it with a drip pan.
Once the fuel lines are disconnected, you can remove the fuel filter. It is located just as the fuel exits the tank, towards the front of the car.

The fuel pump is connected through a fuse in slot 48
The fuel pump in a 2003 Grand AM is connected through a fuse in slot 48. This fuse is located in the underhood fuse block, which is found in the engine compartment fuse box. To access this, simply remove the cover—it should be near the battery under the hood.
If the fuse in slot 48 is blown, it may be due to a short circuit. This could be caused by a melted wire going to the A/C compressor, which is connected to the fuel pump. To fix this, you will need to identify and repair the damaged wire.
If the fuse looks good, you may need to check the fuel pump relay (also inside the engine compartment fuse box). To do this, get someone to put the key in the car's ignition and attempt to start the car while you listen to the relay. If you can hear a "clicking" noise as the car attempts to start, then the relay is working.
If the fuel pump is not coming on, check that you are getting power at the fuel pump with a DVOM. If the pump is not receiving power, this could be due to a faulty connection or a bad ignition switch.
The fuel filter in a 2003 Grand AM is located at the back of the fuel tank. You will need to crawl underneath the car to access it.

The fuel filter may need replacing if it's causing engine start issues
The fuel filter in a 2003 Grand Am is located in the back, next to the fuel tank. It is an essential part of the fuel system. Unless the fuel filter is totally blocked, it will rarely keep the engine from starting. However, a dirty filter can cause erratic fuel flow, resulting in longer than usual cranking before the engine starts.
A dirty fuel filter can cause engine drivability problems. Contaminants that get past a dirty fuel filter can damage, clog, or cause a fuel injector to leak. This can lead to engine issues. A clogged fuel filter can cause low fuel pressure, resulting in a lean fuel condition and engine misfire. This can cause poor fuel mileage, rough idling, and the check engine light to come on. Under heavy loads, a clogged fuel filter may cause the engine to randomly hesitate, surge, or sputter.
If the fuel filter is causing engine start issues, it may be time to replace it. Before attempting to replace the fuel filter yourself, ensure the engine is cool, you have the proper tools, and you have released the fuel system pressure. Refer to the owner's manual for instructions on releasing the fuel system pressure. It is critical to release the fuel system pressure to avoid gas spraying all over the engine or the ground.
To access the fuel filter in a 2003 Grand Am, you will need to fold down the trap in the middle of the rear seat to access the trunk. Lift the carpet inside the trunk to locate the fuel tank cover. Disconnect the electrical connections and the gas lines connected to the fuel sending unit. You will then need to disconnect the inlet and outlet lines from the fuel filter using the appropriate tools.
