3.8 Camaro wont start...no engagement of starter motor when i turn key. battery

wow..thanks for the quick reply ! i have used neutral and the dash lights go completely dark except for the security light when i turn to start .

Sounds like new starter is "sticking"? When starter replaced did you use the shims that the old starter had(if any)? Shims are flat metal pieces that go between starter and bolt on surface. A quick fix is to "tap" starter lightly while someone is turning the key. Be careful not to hit anything electrical. I myself would use something on wood or plastic.
