A faulty fuel damper can produce a ticking noise, which can be heard inside the cabin when the engine is idling. Replacement of the failed dampener should correct this problem.Google+

What my car basically does is that it takes a few seconds for it to start. It is usually during cold weather that it takes a while to turn on. Some of the times it wont even make a clicking noise. When it struggles to turn on, it keeps clicking and clicking.
