Another thing to try it works on my 1996 I dropped my remote and broke it and then started having the same problem, but mine was only when I locked the doors, and used the key to unlock it, thsn sometime it would not start, I called the Chevy house and was told to roll the drivers window down, remove the keys from the switch, lock the car, stay out of it for 3 minutes, then reach in the window unlock the door and it would start this has worked for me for a couple of months now, I just bought a remote from a guy on ebay hope it works when I get it
