Re: [T3] Cold Start Valve on a 72 fi square


your starter solenoid is wired wrong.  There should be a wire coming off of
terminal 50 on your starter to the FI wiring harness.  This allows the pump
to operate when the starter is turning.  Otherwise the pump will turn off
when you turn the switch to start (it only runs for 1.5 seconds when you
turn the switch to "run".  It will not pump again until the engine is
running, that's the reason for the wire from terminal 50
