2000 MC SS will not start. Help
 

I'm having issues pinning down the problem as to why my 2000 SS will not start. Going back a couple weeks the car was running fine, no issues whatsoever. One day it just wouldn't start. No click, Nothing. I had power for dash lights, radio, dinger, etc. But nothing when I went to turn it over. Thought it was the battery, tried to jump, wouldn't. I was able to get it to start by holding a screwdriver to the starter posts. Figured it was Starter that was going bad. For 2 weeks it kept starting without any problems until yesterday. Same issue as before so I went and bought a new starter and put it in. Everything worked fine. Started no problem. Drove around and did my normal stuff. This morning it wouldn't start again with the same syptoms. Battery is good, Starter is new, can start it with screwdriver to starter posts. Anyone have any ideas? Someone told me it could be the key switch???

Any help would be appreciated. I don't want to pay someone to do something I can do myself. I already spent money on a new starter that I apparently didn't need.

Thanks!
