Sometimes my Magnum has difficulty starting in cold weather...so i was thinking it could be the battery. The battery in there now has 730 cold cranking amps...is that enough? I'm in Rochester, and temps have been teens-30's the past couple weeks. usually it has a harder time starting when it's closer to the teens. other than the start problem, everything seems to be running just fine, no codes or weird noises.

rochester NY...the EVIC shows 14.5 volts so the battery is still good. the times that it does not start up, its about a min or two of holding the key in the "start" position, and it doesnt fire up. its just a lot of starter motor whine and thats it, until the HEMI finally starts.
If the starter is cranking, I doubt it is the battery. I would try the cam sensor like Funky suggested.

I wasnt sure if it was maybe JUST under the CCA that the starter needed, so it would crank but not fast enough to start the engine, or what. but yeah, i will look into the cam sensor too.
