That's done by the ECU, so the pump only runs when the ECU says it should! 

When you turn on the ignition, the pump should run for a second or two then
stop, unless you are cranking the engine or it is running.  The trigger
contacts tell the computer if the engine is running.

I'm trying to diag a prob with my fuel pump on a '71 FI Squareback. I'm not
getting a ground on the neg side of the plug that connects to the pump.
Where does this terminal connect to ground?
