thanks for the help guys-- I took in my old battery (it was like 4 years old by the way) in to sears and tested it, it was dead, so they gave me a new one at a discount since it was under warranty. But there's still a problem, I took it home and put the new battery in and the car still wont start! The lights and stereo and everything still work but no turnover. So I dont know if it's the starter or maybe, maybe my old alarm thats still in there. It is a APS500 Prestige and it was there when i bought my car, but it was having problems so i thought i disconnected it... but it does have a starter kill feature but i'm not sure if this would be the problem or not??? also i'm not even sure if it has a backup battery or not, i had the old battery out for at least 2 hours and the backup probably wouldnt have lasted that long right?? anyways any help would be great guys thanks! even just tell me where to find the damn alarm or how to permanently disconnect it. thanks--
