Bought car no key, had to change out steering column got new key. Won’t turn over or start.
Check for battery positive at the “S” terminal on the starter while someone holds the ignition key in the “START” position. If you see battery voltage, replace the starter. Otherwise you will need to trace the wiring to determine why it is not getting voltage. I’ll provide a wiring diagram for the starting system. It may be a good idea to double check your work to make certain you did not leave something disconnected.
