Sorry just seeing this today. The toggle is only used to turn the Starter. I still use the ignition key to turn it off. Now there are 3 parts in the ignition. The tumbler, ignition switch and igniton switch actuator pin.
To figure out which one it is you will have to do some looking. But which ever it is they are all easy to replace.
First, remove the tumbler. Do google search. It should be the same as some Dodge mini vans. All you need for this is a thin screw driver.
Once this is out turn your Key in the cylinder to see if it is bing up. if not then you will have to check the Ignitons switches.
I posted some videos here on how to remove remove these. It is really easy and should only take about 5-10 mins.
Now once you have it apart. If you don't see anything wrong with the actuator Pin. Then you can test the Ignition Switch. Just need a flat screw driver. Insert the screw driver were the actuator pinn would attach to the switch and turn it. If its goog the Jeep will turn over and Start.
I took mine a part last week and found the issue was the actuator pin. So now this is how I start my Jeep. I have not had time to get to the parts store and get the actuator pin. I just use a screw driver in the ignitions switch since I do not have the tumbler installed.
