Nick Onale Junction City, Arkansas - 1992 Chevrolet S-10
Nick hears a buzzing sound after he shuts off the car following a short trip. It doesn’t happen on longer trips. He thinks the noise is coming from the fuel pump. Also, the truck sometimes hesitates when he’s going uphill--like it’s not getting gas. He could have a bad fuel pump relay--he can test it by unplugging it while it’s making the noise, and if the noise stops, that’s it.
