The other day I was driving home and I lost my power steering. I got home and the Fan Belt Slipped off. It didnt break it slipped off. So I put it back on the way it shows on the Manual and now my car wont start. I even put in a fresh battery and car still wont start.

Any Ideas?

Check your battery cables at all ends. Clean them very well.

Also, add your year and trim level to your sig.

My connectors are clean, you can eat off of them if you want too.

I have no idea about the sensor

All I know is it came off and my car didnt die and I got home.

My tempnever hit the red and I was 4 minutes away from home so I kept going

Ok it started for like 5 seconds and sounded like it was going to explode and died.

Now when I try to start it I just hear a click. Starter motor?

You need to do a carefull inspection of the belt path area for any broken or unplugged wires. Damaged sensors, crank,cam etc.
put a wrench on the harmonic balancer nut and see if the engine turns freely.
