How do you remove the ignition switch

I have a 94 grand am that will not start. We have been working on this car for a month and have no clue what to do. I get battery power and radio works. We tested the starter and that is fine. We figured out how to remove the ignition switch. Can you test the ignition switch and how do you know what wires to test.

are you getting spark?
or fuel pressure?

Come to find out it was an extra part that was not suppose to be on the car we had to pay 235 dollars to fix it.

What part?
I have a similar problem, and can't figure out the problem.
