You mean, you were playing with the "code" button on the OBC?

your battery may be drained low enough to still run lights and stuff but not enough to turn over. I know when I was getting mine on the road I had to always have a battery tender on it because the alternator was never really charging the battery.

the "code" feature on the OBC is an anti theft feature, its kind of like a stock kill switch, it uses a programmed code by the owner to cut the fuel flow from the tank to the engine, that way if somebody manages to hotwire your ignition, they still wouldnt get too far. and the only way to turn it off again is by entering that code again, so this is where you hope you weren't too baked to remember the code lool.. if not, check the fuses by the battery in the trunk, i had one blow on me the first day i got mine and it drove me insane till i found out what it was, had to tow it home and everything lol.. good luck!

Could be a bad coolant temp sensor. If the car thinks its warm it'll be injecting less fuel at idle then when it's cold, but in reality the car is actually cold. The problem will go away once the motor is actually warm. Once you can get it to start just unplug the coolant temp sensor and see if it makes a difference.

well considering you've driven the car before, and you only had problems once messing with it.. that can only mean either it had no code and you set one by playing with it, orr you miraculously got the right code that was set before and activated it.. but im not even really sure how it works so you'd have to do a little research and im sure you will find how to reset it, i know this info only because i was curious what that button was for and searched it up and decided not to mess with it after lol (apparently the owners manual tells you how it works im not a 100% on that, if you dont have one i can check mine tomorrow and get back to ya)
