Fuel Pump Wiring
Does anyone use a Hobbs switch to shut off fuel with loss of oil pressure?
And if so, is there an bypass terminal on the LS starter to wire into the switch?
I've always used them for electric low pressure carb pumps, but have not seen any mention of that in this forum.

people traditionally use an oil pressure switch as a way to approximate whether the engine is turning. The PCM can tell directly whether the engine is turning by looking at the crank sensor, and it turns off the fuel pump if the engine stops turning. Most people use the PCM to control the fuel pump.

No, with an oil pressure switch to connect power to the pump from either the starter or a switched circuit.
