shut truck off and went to start back truck just turns over and wont start. fuel pump relay clicks but don't hear anything from gas tank area. any help would be greatly apricated

 

Spray some gas or starter fluid into the throttle body. If it starts and runs for a few seconds you a fuel problem, most likely the fuel pump. If it still does nothing then you most likely have no spark. Is the check engine light on? If it is read the codes, it will lead you in the right direction.
