So I decided to go ahead and change my spark plugs & wires today. That actually went pretty well considering it was first time i've changed them on these cars. So I clean it all up, go to start it. Click, pump primes, radio's on; I go for the start click and DEAD, the whole thing just dies without turning over. I try to turn it on again, and nothing. Zero juice.

So I consider maybe the battary is screwed up, I replace it with a Delco battery and jump it for a half hour. When I try to click it, all the car does, is what can be best described as a banging sound. I checked the wires at the starter, and they all look good. I didin't yank on anything when I changed the plugs. I'm really at a loss now as to what to do, and could really use some help!

 

Clean your battery terminals, You are not making good contact. This is very common. Corrosion will build up inside the screw on terminals and the cable will just make enough contact for the radio and such, but the second you turn the lights on or you try to start it it will arch and and render even the faint contact it was getting useless.
Soak the terminal calbe ends in baking soda and water in a glass (about 1 tbsp of baking soda) or just use good ol full strength Coca-Cola in a glass.
