Normally, you should be able to see the plunger pull up into the solenoid.
However with no pressure in the OD (or if the adjustment has slipped), the
plunger may have not fallen back down.  If it is already up, you might not
see it move.  Move it to be sure it is down and try again.

And as Bud already pointed out, check the voltage right at the solenoid with
the solenoid still connected.  The solenoid draws a big wad of current when
it moves, so any little resistance in the circuit (like a dodgy connection
or a bad relay) will keep it from getting the current it needs.
