Will not start after replacing steering column?

The steering column had broken where it tilts, so I located one at a junkyard, (was only at salvage yard for short time). I stripped it down and replaced ignition switch, turn signal switch and everything from broken column. I have to add that car has an aftermarket alarm and I did wire it back in. So I got it all put back together, turned key forward, everything works! Next I tried to start the car and nothing, again all lights, radio, heater/AC etc., work fine but starter did nothing. I tried cleaning the key and using the spare(have chip on key) i unplugged the computer and even tried the rest. I have tried every thing I know to do. never have had this much problems with a car. thank you very much.
