Seems like if I let my car sit for a day it stutters to start. Some times i have to try 3-4 times for it to fire up.

Now I ran a OBD and there were no codes. I replaced my sensors a while back. It was taken cared of when I first gotten the cam sensor positioning system error code.

So i checked the volt meter and it registered 12.5 when i put the key in the ON position and when its turned on it's at 14.5. I'm thinking it might be a battery issue. Any insight on this issues?

 

Checkers/Autozone will check your battery/alternator if it checks out try turning the key to the on position a couple times before turning it over. If it starts better you're probably looking at a fuel pump issue. This just happened to a buddy of mine last month.
