no power or crank to my 97 camaro just replaced the battery the starter and a alternator ?

 

Check neutral safety switch or clutch switch if manual.
Or swap starter relay.

 

is the security light on

 

Good point on security. Insert key into tumbler, disconnect column connector and measure ohms into harness checking if socket reads key chip.
No reading, then replace socket after removing steering wheel and verifying car registration at dealer for replacement socket.
