So here's a weird one. Truck has been perfect, no issues other than low heat but that's known and I plan to fix it when it's not near 0 outside. Parked it last night after going out and this morning it's completely dead. I put the battery charger on it and as soon as it got power my stereo turned on without the key being in the ignition. Had to pull the IOD fuse.

Anybody have a clue?

 

Battery's can do crazy things when there cold....

 

Is that a stock radio? It shouldn't have power when the key isn't even in it.....

 

No, it's an aftermarket unit. It did eventually start working right once the battery got some juice in it. I think RacerHog was right.

 

Drive like you use to.... It might have to run a few drive cycles to act completely rite....

Oh...One other thing... Down in your sig... Lucas fuel additive will help with some mileage.

Just an FYI
