The seat is designed to hinge forward, but be cautious of any wiring harnesses or cables connected to the seat. Disconnect these carefully if necessary, noting their positions for reassembly. Place a protective cloth or towel on the floor to avoid scratching the interior as you lift the seat.
With the seat removed, you’ll have a clear view of the fuel pump assembly, typically located beneath a metal or plastic cover. This method, while not as convenient as an access panel, provides sufficient space to work on the fuel pump. Always refer to the vehicle’s service manual for specific instructions related to your Malibu’s configuration, as variations may exist across trim levels or optional equipment.
Reinstalling the rear seat is a reverse process, but ensure all bolts are tightened securely and any disconnected wiring is properly reconnected. Test the seat for stability before driving to prevent it from shifting during operation. While removing the rear seat isn’t the most elegant solution, it’s a practical workaround for accessing the fuel pump in the 2010 Chevy Malibu.
