I of course have a 2003 kia sorento. i can go out in morning and turn the key and nothing happens. the battery has plenty of power the lights come on as to say it is going to start but that is all. it is like there is no power at all but like i say it has power. but there is more to the story, you can go back out an hour later and it will fire right up with no issue what so ever and continue to do so for days until it does it again about not starting.....what the heck is going on??????
