If your car is properly wired the fuel pumps should not run until the fuel metering plate/control arm is deflected enough to activate the electrical switch connected to it. Cranking the engine and drawing air across the metering plate will delfect it and start the pumps running. I believe the switch is normally closed, and opens when the arm deflects enough.

You may want to check the connections on that switch, at the back of the fuel distributor. Pull the electrical connection (green plug, or is it blue?) to the switch. If everything is operating correctly, pulling the plug will cause your pumps to start running. If they're already running to begin with, then dirty connections or faulty switch may be the cause....or, the metering plate control arm is hanging up and not fully returning to rest when you shut the car off.
