That is the control side. You should have battery voltage there. The other terminal goes to the PCM to be grounded. When the PCM grounds the control side, the load side is activated.
As far as the key on, there will be no ground to the PCM. IN the on position, the PCM will ground the control side for 2 seconds to allow the pump to prime. When cranking, the PCM will ground it all the time.
Check the fuse listed for the control side. I believe it is ABS IGN fuse.
