When the airflow meter plate is pushed down, the safety circuit is opened. Pulling the plug off the switch also opens the circuit.
As mentioned above, the pump relay is in the fuse box. With the box cover removed, push down on the airflow plate while listening for the click of the relay in the fuse box.
The relay supplies power to the pump when: 1) the engine is running, and the safety circuit is open, and 2) when the engine is being cranked by the starter motor.

Because the fuel pump is heard to run when the airflow plate is depressed, you may conclude that the relay is operating. It may take the assistance of a helper, but by repeatedly cycling the plate up/down, while listening in various places around the car, the clicking of the relay will reveal its location.
It can hide, but it cannot run away.
