Steven, You are the second person to indicate that production (street) cars have an impact type safety switch. My experience with GM products is that the fuel pump is turned on when the ignition key is in the start position, and when the engine starts, the oil pressure switch keeps the pump on. When the oil pressure drops, the switch opens and the pump stops.
Are you sure about the impact type switch on Ford products ?
