Car won't start after replacing Ignition Switch?

So my ignition switch has been a little sticky feeling, I had the car turned on and driving then I went to park it, i turned it all the way off then back on half way to listen to the radio without the engine running. After 20 mins i went to start it and the key just spins freely. Not only that but when i take out the key the battery stays on in that mode, it won't crank or turn over, and it won't turn off the power. So i tested the starter by connecting positive and negative cables connected to the starter and it turns on! But then i couldn't turn it off either… So i pulled the fuses to kill it. I thought it was the metal piece on the cylinder that goes into the casing on the steering unit, but after replacing the ignition cylinder it still does the exact same thing. I can feel it want to catch but it's like the housing unit is off track. Any way i can fix this at home? I have little money and I can't find a way to take off the whole housing unit, nor find it sold anywhere or how to fix it. Thanks for the help! 1997 ford taurus, automatic, v6

You boo boo'd placing the switch. Don't fret, we all do it. Took a couple tries with a 95 Olds recently for me. Just get back to the mount points, loosen the screws and reset the switch position. Make sure those screws are tight once done. If, this is a rod type? Like the Olds? Where the switch is really at the top of column below dash? Check that the rod is placed in the correct slot.of the switch. Often they slip while mounting.

Go back and check your work. Sounds like a positioning problem. Switch alighnment.
