2002 Sonata just quit running

2002 sonata 71,534 miles 4 cyl auto trans
on my way home from work pulling away from a green light it just quit in the intersection it turns over all lights work fine just doesn't start I checked the timing belt it has a few teeth missing but it seems ok not slipping. I know this needs to be replaced but could this cause my problem? Also when I turn the key to the on position and listen should I hear the fuel pump? Could it be a fuel problem? Help I have lost a day and a half at work because of this.
