Ignition column replaced and now it will not crank?

I just replaced my ignition column for my car while using the same ignition lock cylinder to keep from buying and using a new key. After the replacement was installed, my car would not crank. I put the old switch into the new column I had installed to see if the issue was lying in the key and new switch, as it may not be able to read my key with its new switch that comes with the new column. But the same problem still occurs. The car doesn’t crank.
