My '89 Bird has been experiencing the problem with starting my car with the anti-theft for two years now. I'm going to try some persons answer and rub a pencil eraser on my anti-lock key connector. I don't know if it will solve anything but my advice is if you can afford it, start looking for something more economical and relliable.
