I recently purchased a 2004 Santa fe with 180,00 miles on it. Drove the vehicle for over a month before I had an issue with it not starting. When I turned the ignition to start I had no crank but all the appropriate dash lights came on and I can hear the fuel pump working. Since this first incident I have had a new battery installed, a new neutral safety switch installed and a new starter but the problem still happens. When it does this I turn the key off and then try again, it starts. Any ideas??
