Sorry but these engines do not have a timing belt, they have a timing chain. The timing cannot be checked it is computer controled. Plus going to autozone is not a good idea for automotive advise, they are parts people selling parts, thats all they know and all they do they are not techs. Why don't you post back with the problem you are having and we can go from there. Also scan for any dtc's it will help.
