I have a 1995 Buick Park Avenue with a security light problem. When it is on, it will not start. What I mean to say is, it will not crank. At one point I saw it on when my wife was driving, but it went off in thirty or so seconds. I'm not sure if it was on when she started it, but it always goes off after it starts for me. The only thing that seems to help is waiting and slamming the car doors. I have tried both keys, same problem. It is intermittent. The starter has been changed. Battery is good. The 8th number of the vin is K.
