I have a 2000 pontiac Bonneville sle and it was running fine it stalled yesterday on me n after a bit started back up and ran fine the rest of the night, This morning It started fine and then 15 mins...

I had the same problem with my 2000 Bonneville SLE and I replaced the crank shaft sensor and it solved the problem. The crank shaft sensor is located behind the harmonic balancer. You have to take the balancer off to get to the part. You will need a puller to get it off. You will also have to take the fly wheel cover off and hold the fly wheel when you remove the nut from the front of balancer.

I need a diagram for a serpentine belt routing for a 2000 pontiac bonneville sle

You probably have it fixed by now, but you should have a 3.8L V6 (no supercharger).
The belt routing should be the same as my Impala 3.8L.
