Sounds like a weak battery issue. Is it on the original battery from 2012? Either way, if everything turns on but the engine is "clicking" then that's usually just a weak battery. Advance Auto will test the battery for you for free and even charge it over night for you for free.. but even then you'll probably need to go and get a brand new battery for it.So when we turn the key it wants to turn over but doesn't. How could I check those? And I know its not the spark plugs.
