Not sure how old the battery is. I've had the car for 5 yrs. I checked the battery (12.78v 710 CCA). When I hooked up the negative lead of the battery tester the negative battery connection to the frame seemed the move, possibly a little loose. I removed the negative cable, clean the terminal, let it sit for about 45 mins. Then reconnected the cable and ALL IS WORKING! Hopefully that was the problem. Thanks for your help.
