Did you take the tensioner off the timing cover for some reason?

The tensioner is what you have to rotate with a socket driver or breaker bar to relieve tension on the belt so that you can remove or install it. Did you also unbolt it from the engine (timing cover) for any reason?

Where on the tensioner are the sparks coming from? Can you take a pic and then circle the area?

^ What he said.

Be sure the tensioner is attached to the timing cover firmly (it's just one bolt, more or less in the center of it. I forget the torque spec for that bolt, but it's not much - maybe like 20lb/ft or something). If it is, and it's grinding up against the timing cover then the bearing/bushing in the tensioner is shot and the whole thing needs replaced. Not a big deal - it's about $35 at Autozone and 10 minutes of your time.

Don't let it rub against the timing cover very long; the timing cover is aluminum and not very thick, and the pulley on the tensioner is steel. The pulley will win that fight, and when it does it will be a much bigger job. When my tensioner went, it took out about 1/16" of material from the timing cover in less than a few minutes.
