But when I connected the Vac pump to the EGR Solenoid Valve (key off/engine stopped) it passed vacuum through it, or in other words was "open". Is this normal?




Nope, I don't think so. It should be closed at idle and at KOEO.

Now here is the part where I may have messed up. I removed the EGR Solenoid Valve and connected a pair of jumper wires to a 12v source. Got a huge arc, so either the solenoid windings are shorted or I just fried it.





Messed up is right. The EVR solenoid runs on a 150hz signal from the PCM. You can't hookup 12 VDC directly or you may cause damage to the solenoid.
