A co-worker called this afternoon with questions about his Intrepid. When the car has ran it sometimes will not crank over after running errands. If he or his wife leaves it sitting for about 20 minutes it will crank over and start right up. He had a new starter put on about a week ago, this did not help. He said he hears the fuel pump run and all lights are good but will not crank when engine is hot. Any help would be appreciated.
