The fuel pump relay of the Buick Regal is located in the engine compartment, inside a fuse box with labeled position numbers. Location of the fuel pump relay: The fuel pump relay is situated under the car hood, at the bottom of the engine compartment, between the left side of the car transmission and the car battery. To locate the fuel pump relay, you need to first open the engine hood. Working principle of the fuel pump relay: The fuel pump relay is primarily controlled by the engine ECU.

I've handled the Buick Regal model many times before. The fuel pump relay is located inside the fuse box in the engine compartment. Open the hood, and you'll see a black box, usually near the battery or windshield side, with the exact position varying by model. It's best to refer to your owner's manual or check the diagram on the box cover. Inside the box, there are a series of relays, and the fuel pump relay will be labeled "Fuel Pump" or similar. This setup ensures the circuit is close for better control of the fuel pump. If the relay fails, the fuel pump won't supply fuel, and the car won't start. For inspection, I recommend turning off the engine, removing the key, and disconnecting the battery's negative terminal to avoid short circuits—safety first. If you can't locate it, you can use a multimeter to test continuity or refer to online diagrams for assistance.
