I am getting the car to start my 2008 dodge charger, it starts fine so about 15 minutes to start it,

So when the vehicle cools down it starts? This is an indication of a Ignition Control Module, that can be taken out and tested, If this is the 5.7L. Also I would have it scanned for any trouble codes.

No lights are on(meaning engine lights), this morning I was driving it and when I cut it off and when into the store and came back out about 5 mins. later and try it, it wouldn't start at all, It would crank but not turn over it tried to start but it was a 5-6 second delay in starting but in this 5-6 second delay its still in cranking mold without me doing anything usually I would turn it off because I don't want anything to mess up, but this time I just let it go to see what it would do. It just crank out the problems is getting worst please help

Sounds like you are not getting a good spark, or there is a fuel issue. Fuel pressure would have to be checked if there is nothing wrong with the ignition control module. Like I said, that can be checked, but needs to be taken out. Fuel pressure would be next if need be. Gotta start diagnosing the problem.

OK will try that, and let you know
