I bought this truck about a month ago. It has 206,000 miles. I put a brand new battery in it because the one that was in it was old. It has run absolutely perfectly. I had it detailed last week. The guy cleaned the engine. Not sure if he used water or not. I'll ask him tomorrow, but it has started perfectly ever since I got it back from him. I even took a road trip to the mountains this past weekend with it. NO issues whatsoever. Then I tried to start it tonight and all the lights come on, all the remote functions work, radio and windows work. Everything works. The only problem is the fact that it doesn't even try to turn over. Nothing happens. Just makes the normal "ding, ding" sound and all the normal lights come on. It does make a slight click and then nothing happens. I tried to tightened the bolts that hold the terminals on and didn't help a thing.

As you can see by my username, I am not a mechanic. Please help !
