I believe there is circuitry in the fuel pump relay wiring to allow the fuel pumps to run for 5 sec. or so at startup. Otherwise there would be no fuel pressure to start the engine. This may be why your engine starts and then dies.

On my car, I have the connector on the air meter but it is not connected to anything because of an update to the circuit wiring. My understanding of this switch is that it cuts power to the fuel pumps if the plate is in the upper position and the key is in the "on" position but the engine is not running.
