Symptoms of a failing fuel pump
The fuel pump is an essential component of a car's fuel system, delivering fuel from the tank to the engine. If the fuel pump fails, the car will not run.
- Whining Noise: A whining noise coming from the fuel tank area when the engine is running could indicate a failing fuel pump. This noise is often a precursor to a loss of pressure or total failure.
- Stalling: If your car stalls but can be restarted after several minutes, it could be a sign of a failing fuel pump.
- Trouble Starting: If your car struggles to start or won't start at all, it may be due to a faulty fuel pump. This issue can be more prominent when the fuel tank is less than a quarter full or when parked facing uphill.
- Lack of Power: A failing fuel pump may cause a loss of engine power, resulting in poor performance or intermittent bursts of power while driving.
- Engine Misfires: Engine misfires, especially when the fuel level is low, could indicate a problem with the fuel pump.
- Long Cranking Time: If it takes a long time for your engine to turn over, it may be due to insufficient fuel delivery from a failing fuel pump.
- Check Engine Light: A failing fuel pump can cause the "Check Engine" light to illuminate.
If you suspect that your 2003 Chevrolet Malibu's fuel pump is failing, it is recommended to consult a professional mechanic. The average cost of replacing the fuel pump in this vehicle is between $1,038 and $1,325, but it can vary depending on the specific car. Additionally, it is advised to use OEM (Original Equipment Manufacturer) parts for a more durable solution, as cheaper alternatives may not last as long.

Fuel pressure test
The fuel pump in a Chevrolet Malibu is designed to be long-lasting, but like any other part, it can fail. A failing fuel pump will not create enough pressure in the fuel system, possibly causing a loss of engine power or preventing the car from starting. It may also cause the check engine light to come on.
To perform a fuel pressure test on a 2003 Chevrolet Malibu, you will need to use a fuel injection test set and T into the fuel rail lines. This is because there is no fuel rail pressure test port on the vehicle.
You can test the fuel pressure at idle and full throttle; it should be 38 psi at idle and 44 psi at full throttle. When the fuel pressure regulator is disconnected from the vacuum line, the pressure should be 52 psi at idle and full throttle. When you push the "test" button on the fuel pressure tester, the pressure should drop to 25 psi, and when you shut down the engine, the pressure should drop from 38 psi to 28 psi.
If you are not comfortable performing these tests yourself, it is recommended that you take your vehicle to a repair shop or a service center that works on Chevrolet vehicles to have them diagnose and address the problem. The average cost for a fuel pump replacement across all vehicles is between $611 and $894, but for a Chevrolet Malibu, the cost is typically between $1,038 and $1,325. There are less expensive pumps available, but they may not last as long. Additionally, you may need to replace the fuel filter if your vehicle is equipped with one.

It is also important to have a safe and accessible workspace and to take the proper safety precautions, such as pulling the fuel pump relay and disconnecting the battery.
Next, if possible, reduce the amount of fuel in the tank to minimize the risk of spillage. Clean the area around the fuel pump to prevent dirt and debris from falling into the fuel tank. Then, relieve the fuel system pressure by disconnecting the negative battery cable. Disconnect the filler tube hose and the electrical connection to the pump. Support the fuel tank with a jack and a block of wood. Remove any retaining straps or bolts holding the tank to the frame, then lower the tank and disconnect the fuel lines.
Remove the old fuel pump from the tank and compare it with the new one to verify that you have the correct part. Install the new fuel pump and reassemble the fuel system. Finally, test the new fuel pump to ensure that everything is functioning properly.
It is important to note that replacing a fuel pump can be a challenging task, and it is recommended to work in a well-ventilated area to minimize the risk of fire or inhalation of harmful fumes.
