Where is the fuel pump relay switch on a 2010 Malibu?

The fuel pump relay location on a 2010 Chevrolet Malibu varies slightly depending on the specific trim level and whether it's a sedan or a coupe. It's usually found in the underhood fuse box, but not always directly labeled as "fuel pump."

Your best approach is to:

1. Consult your owner's manual: This is the most reliable source. It will have a diagram of the fuse box showing the location of all relays. Look for relays related to the fuel system, fuel injection, or engine control.

2. Check the underhood fuse box diagram: Even without the manual, the fuse box cover *should* have a diagram printed on the inside of the lid. Again, look for relays related to fuel or the engine.

3. Use a multimeter (if comfortable): With the key in the "off" position, you can test relays to find the one related to the fuel pump. This requires some electrical knowledge, and it's best avoided unless you are comfortable working with car electrical systems.

Without your owner's manual or a visual inspection, providing an exact location is impossible. If you're uncomfortable working on your car's electrical system, it's best to have a qualified mechanic locate and check the relay.
