What can I do? When I turn the ignition it just runs. It IS NOT turning over. It did it today when I was coming home from work, but then it turned over and started. I ran to the gym and when I got in to leave, it wouldn't start. When I turn the key to start it just runs (I can't explain it, but it doesn't turn over). After awhile, it started after I tried and waited a few times. I need the truck for transportation. Please Help!!!!
