Well, lately my car has been having trouble starting. Sometimes it starts right away and other times it won't. when it doesn't start, the car cranks as if it wants to but when I look at the speedometer and it says that my battery is pushing about 6 volts. and I just got a new battery and I got my alternator tested and it's fine as well. So I'm not sure what's going on, especially since I'm new to cars. Any suggestions for what the problem could be?

 

Sorry, I meant to post this in the specifics section.
