Where is the fuel pump relay switch located on a 2007 Chevy Malibu?

The fuel pump relay location on a 2007 Chevy Malibu is in the underhood fuse block, often called the Power Distribution Center (PDC). However, it's not always a separate, easily identifiable "fuel pump relay." Instead, the fuel pump circuit is often controlled by a relay within the PDC that might be shared with other components.

To find it:

1. Locate the underhood fuse block: This is usually a large black plastic box under the hood, often near the battery.

2. Consult your owner's manual: This is the best resource. It will have a diagram showing the fuse and relay layout of your PDC. The diagram will specify which relay controls the fuel pump (or which fuse/relay is part of the fuel pump circuit).

3. Look for a relay that corresponds to the fuel pump circuit in the manual: The manual should list the relay by number or location. You might see labels such as "Fuel Pump" or something similar. Even if you don't see "Fuel pump", pay attention to the circuits described.

4. Use a multimeter (optional): If you're comfortable with basic electrical testing, a multimeter can help verify if a particular relay is the one controlling your fuel pump.

Important Note: Working with automotive electrical systems can be dangerous. If you're not comfortable working on your car's electrical system, take it to a qualified mechanic. Improperly handling relays or fuses could lead to damage or injury.
