Why won't my 89 Chevy caprice start? on 1990 Chevrolet Caprice

I have a 1989 Chevy caprice I have replaced the steering column and the starter and for some reason the car won't start I have also replaced fuel pump, all computer chips and ignition module, I really need some help so if u could give me some advice on why the car won't start I would appericate it.

Won't CRANK, spin over? Or won't START, fire up and run?
Agree with pushrod. Not CRANKING and not STARTING are 2 very different things given what you said about replacing the column.
