Ignition switch problem Please Help!!!

I have a 68 firebird. I think I have a problem with my ignition switch. The volt meter is showing 12 volts with the key in the on position. When I turn it to engage the starter i'm showing 0 volts. Electricity is not getting to the starter from the switch. I'm trying to take the stinking switch out and am having an awful time. Any tricks in getting the darn thing out and could there be some other problem causing this. It has done this about 4 times but it eventually cranks after some time. It will not crank and I'm in a tight spot. I need to get the thing cranked and back to my dad's garage. Any help would be GREATLY appreciated.

To get it back to the shop:

You need to put 12v to the small wire terminal on the starter solenoid. That should be a purple wire 'if' it's like a Chevy. If you have a factory automatic trans car; you can jump that purple wire at the 'neutral safety switch' which is inside, under the dash, near the bottom of the column (on most old cars).

Before jumping that wire, make sure it's not in gear.

That will crank the starter, and if the key is "on", it will crank & run. (if the starter is ok)

After you get the car to the shop; Put the voltmeter at the heavy feed wire to the ign switch then check volts when trying to key-start it. If it stays near 10+ volts, the feed is ok. Now check the volts to the "s" terminal wire at the ign switch as you try to key-start it. If you have 10+ there, the key switch is ok on the cranking part of it. If it still won't key-start/crank over, then trace that "s" terminal wire down to the neutral safety switch(auto) and if ok there, then trace it from there through the firewall to the starter.
