i have a 89 accord that when it sits in the sun apparently gets so hot it just will not start untill it cools off .i mean like in the parking lot not started all day just wont start. is this a common problem? i was thinking its vapor locking but i dont know roll the windows down wait about an hour and it starts right up! is the computer over heating? vaper lock? someone suggested a bad coil but i dont see it car runs fine
