DEFAULT WITH THE SERPENTINE BELT

You can reroute the serpentine belt to no air. Your parts shop will be able to sell you a belt to accomplish this.

take it back off and check the routing for the belt
grooves in belt to grooves in pulleys and flat back on flat pulley surfaces

If it quits and starts back up, its going to be tough to diagnose.
It needs to happen on demand to track down the problem, otherwise you may never find it and know its fixed.
Could be the key switch, a relay, an ignition component, or something else electrical.

Only thing that would cause your vehicle to not start after replacing a serpentine belt, is maybe a wire was knocked off during installation. Your car will run, even without the serpentine belt on it (don't do it, it will cause it to overheat very fast and may cause damage). So just check around, odds are its something simple

Go to; daycoproducts.com, click cars and trucks, then go to serpentine belt. Then on the right side of the screen click on finding your vehicle. Then get the illistration number and click on illistrations, go to that number it should something 6-? or 7-?. It's a pretty good websight.

with the belt off,try to spin each and every pulley,and water pump,alternator,idler pulley,automatic belt tensioner pulley,sounds like one froze up and took the belt out.

Sounds like you have something locked up.

Take a picture/draw a diagram of serpetine belt routing.

Remove the belt, then try turning each individual item the belt powers to see which one is locked up.

I'd start with the AC Compressor first, then alternator, the belt tensioner, power steering pump, and whatever else is powered by the belt.

The only thing that comes to mind is the belt may be set to tight.

check to see if the injectors are working....

with the belt off try turning all the pullies to make sure nothing is froze
