There are 4 round relays mounted together near the ECU, the fuel pump relay should be one of these.

You do know that the fuel pump only has power for 2 seconds after the ignition is switched to on. It only comes back on if the engine starts.

If you join the 2 green test connectors together, the fuel pump should cycle on and off with the ignition on at a ratio of 1 second on, 1 second off.

Nah, my fuel pump relay and ignition relay was mounted above ECU on a bracket. The four round relays are more forward just above fuse box and do fans and stuff - on EA82T mpfi anyway
