2001 Galant Not Starting
 

I have a 2001 Galant and it is not starting. It just clicks when the key is turned. We bought a new battery, a new starter and we had the alternator checked. We've also made sure all spark plugs are fine and checked the fuel pump as well. All of that is fine and it still does not want to turn on. The cam and crank shaft sensors were just replaced in March. It was fine last week and one morning I went to leave and it would not turn on not even with a jump. I am at a lost and so fusturated as to what else it can be. Any ideas?
