Need help,something is draining my battery. It wont drain while parked checked voltage after sitting all night drops down to 9 while driving then creeps up and then down so I know its charging,checked starter connections. Bought new ground strap polished ground connections,checked everything in the trunk. Battery tested it's fine. All fuses checked. Also when battery is charged the car starts slowly then you do it again it starts fine. I've looked through the forums nothing quite like this. I've never seen a car drain a battery this fast.And my OBD port quit communicating so no codes. Any help you could give me would be much appreciated.

The "usual" problem is the little trap door in the ignition key hole. If it stays stuck open, the car thinks the key is still ignition and does not shut down. You need to lubricate this trap door to make sure it closes every time. Resist the urge to use graphite as it can stain the key and then your pants pockets. A silicone spray might be a good start. To my knowledge, this leads to a slow drain, it may not be enough to explain the faster drain you are describing. Unless the battery is old and a small drain quickly kills whatever margin you have left.
Best of luck, keep us posted.

Your going to have to go digging. You might not get as lucky as the guy above (the OP) who found a loose or corroded major cable at the starter. Ya MIGHT, but maybe not...
Watch this video and check back....I'm interested to know what ya find when ya find it...
