I recently had my mechanic replace my ignition assembly (aftermarket). It worked okay for 3 or 4 days. Now when I start the car and release the key, the ignition switch recoils too far back causing the motor to shut off. I have removed all the panels inhibiting access to the ignition components and steering column. I have removed and reinstalled the ingition/key assembly and there is no improvement. TI confirmed that there are no springs or tensioners within the switch. I can't figure out how to access the spring/return mechanizm to diagnose this problem. The screw which holds the wiring harnes to the ignition assembly on the left side of the steering column is held on by 2 screws with inverse star bit heads and no one seems to have a tool to remove them. Do I need to remove this coupling to access the recoil mechanizm? Am I wasting my time? Please help.
