I'll answer this with the same answer I gave on your other DUPLICATE thread:
Disconnect the negative battery cable and connect an Amp Meter between the two.
If something is staying on, you will see a Amperage value.
Start pulling and reinstalling the fuses (one at a time) and observe the meter. Once you reach the circuit which is staying on, the meter value will drop to zero. That is your hint as to where to start looking.
Be aware that there are some systems that do stay alive, even with the key off.
Both the clock (and I believe the ECM) require a uninterupted power sourse, so plan accordingly. The amp draw for these components will be in the milliamp range and can be disregarded. It's so small a draw that it would take months to drain down a battery.

Well I'm assuming that if the lights are turning on it's not your battery unless its only got enough juice for the lights.
In accessory does the radio and everything work?
If so I doubt its the battery.
I had a similar situation with my car.
Read this forum... Let me know if it helps
In my case it was the main relay that was causing the car not to start

Anything over 50mA is an excessive current draw.
