In a 1987 Grand Marquis, the fuel pump is powered by the vehicle's electrical system, specifically through the ignition switch and a relay. When the ignition is turned on, power is supplied to the fuel pump relay, which activates the fuel pump to draw fuel from the tank to the engine. The system is designed to operate only when the engine is running or during the initial start-up phase to prevent fuel leakage and ensure safety.
