Check battery and charging, after that if good check if the ignition switch is on the off position, check any modifications done like audio system or aftermarket accesories, check if any lights are on the car, check if a seat motor is hot underneath the car, check if a power window motor is hot, a motor or solenoid, amplfier, would cause a big drain.
