that doesn't really give us any details. in order for anyone to help you with this, you have to put down some more details on the situation. we can't just diagnose something because you say the car doesn't start.

If it doesn't start after it sits for longer than 12 hours, your battery may not be holding its charge. This could mean a power drain somewhere (improper wiring of sounds system or alarm, perhaps?) Or that the battery is bad and is no longer holding its charge.
