The relay is energised by virtue of switching the ignition on, the relay is there simply to reduce the load on the ignition switch.

That's the "main relay" The fuel pump is switched by a second relay which is energised only when the ECU detects cranking or running of the engine.

Both of these relays are purple and they're side by side at the rear of the relay box by the battery.
