Hi Guys
I recently replaced the steering column on my 87 fiero GT with a spare I had in stock as the tilt mechanism had become very sloppy. While this solved the wobble, it has introduced a new problem

When I put the key in and turn the vehicle on, it often will not turn. I can fiddle around with the "key lock lever" and eventually the key will turn and everything is fine. A secondary, and maybe unrelated issue, is that the steering column lock doesn't seem to be operative.
I would appreciate any suggestions as to what the issue might be and how to solve it.
Regards, Richard
