Is there a fuse for this
You need to check for OBD Codes,
if you have any dash light on
Fuses-- you can check them all
Replacing a blown fuse won't do anything,
they blow for a reason
Sounds like an emission problem. Take it to your local parts store (AutoZone. Advance, Oreilly's). They usually connect the scan tool and check for free.

This is the diagram but you should have factory belt diagram sticker is still somewhere under the hood
If not:

To replace the serpentine belt on a V6 3800 you must jack up the motor and remove a motor mount. You must then use a breaker bar with a socket (13/64") and pull it toward the front of the car to release the belt tensioner. Put the new belt on, tighten it, put the mount back on, and lower the jack.
Driving without a belt can cause the motor to overheat, will cut power steering, and will not recharge the battery, so you should probably get a tow
Good Luck

Code PO442 means you have a small leak in your evap system. Codes PO452 & PO453 refer specifically to the fuel thank.
Although it will be a good idea to change your gas cap, I don't think it is where your problem is coming from.
I would check the vacumm hoses for loose fitting or small cracks.
Specially if you had your car worked on recently.
Good luck
