There are a few potential causes of a ticking sound when accelerating your GMC Sierra. One possibility is that you have a loose bolt or screw in your engine. Another possibility is that you have a worn-out timing chain or belt. A third possibility is that you have an exhaust leak. If you cannot determine the source of the ticking sound, it is best to take your vehicle to a mechanic for diagnosis and repair.
