i was hearin a noise didnt think anything of it my battery light turned on kept driving then 15mins later the car just shuts off i let it coast i pop the hood and the main pulley is gone nothing there at all what kinda damage could i have done im goin ot get a new pulley tomorrow but my timing is proply shot right>>?????

 

If the timing belt is still in place (which is likely) then there shouldn't be any real damage at all. Install and properly torque the new pulley, fully charge your battery, and you should be fine.

 

i would suggest against driving it as well since that pulley is also your hamonic balancer. good luck
