This is for a turbo car. It has 2 fuel pumps one will only turn once under boost. This will be done via Hobbs switch. Also I would like to add in a fuel pressure safety switch that will shut off both pumps if there is a failure. The ECM supplies 12V to the pump that will be for just driving around no boost.

So what would be the best way that I can shut off power to both pumps if the fpss see's a problem?

The ECM should control the pumps.

Otherwise pumps & valves are controlled by the charge light circuit, else an ignition sensing circuit.
