Wife's 09 Mega Cab is having a starting issue. Turn the key & all we get is a click. Batteries & terminals have been checked & are in good shape. I've replaced the starter relay & still nothing but clicking. Any ideas??

 

Sounds like the starter is bad, brushes worn out. If batteries and connections are clean and tight. Try tapping starter motor while someone turns ignition key, if it starts then replace starter or rebuild it.

 

Thanks! Will give it a shot!
