I have a 1988 GL10 Turbo Wagon. I have an intermittent starting problem. It starts several times and then it does not. All power comes on and there is a slight click but the solenoid will not engage. I continue to turn the key to start and after 10 or 15 attempts it will engage. The battery is new and the charging circuit is operational. I replaced the starter with a new - not remanufactured - starter. The problem continues. I am now pretty certain the actual ignition/key lock switch is bad. How do I remove it? I have a tilt column. I have heard there is a video on YouTube but I cannot find it. I am ok putting in a new switch and key keeping the old key for the doors but I might have the tumbler keyed to the old key.
