2009 grand prix won't start, just clicks when the key is turned. charged battey overnight and same result. replaced battery and worked fine for a few days but now it's the same problem. i put a voltmeter on the battery with the car running and it shows 14.6v. with the car off it's reading 12.5v but still won't start. what else can i check?
