V8 two wheel drive automatic.

My fuel pump will not turn off. I need to know where the fuel pump relay is on my vehicle. It is a wagon.

Hello, my general Caprice information says the relay is located under the hood, passenger side, close to firewall. The primary wiring colors at the connector are green, orange, black, gray.

You also need to check the oil pressure switch. Some systems have an oil pressure switch in the fuel pump circuit. If that switch gets stuck in the closed position, the pump will continue to run.
