Ignition when i go to turn my key forward to start the car it feels like there is nothing there just spins, feels like it isn't catching anything to start the car. what part of the system could have broke inside, so i know which part to replace! Thank You in advance!

The actuator inside the sterring column that the lock cylinder turns is boken, this is a very complex job and is not for the home tech without a factory service manual.

The ignition switch has the detents and spring inside of it. The lock cylinder where the key goes in, just allows you to turn the cylinder which then turns the ingnition switch. The ign switch has the electrical connector going to it.

You have to remove the lock cylinder and the upper and lower plastic shrouds to access the ign siwtch.
