Is car stick or auto? could be neutral safety or clutch interlock switch. Does it crank? You say doesn't start or is it that it doesn't run. Looking at wiring diagram steering column plug has start wiring in it.
Car is auto, I'll check the neutral safety switch. No dome light. No screws holding the dash bezel and dash in. Does the dash need to be grounded for all the dash lights and dome light to work?
Don't think I unpluged anything on the steering column
