RE: Starter won't engage !.
I agree with born, if it's now suddenly starting with out any adjustments, somethings loose. I had a problem with my Saturn similar to this, where there was a loose connection and until I found it, it was a crapshoot whether I would have electricity or not. When it was warm, the metals expanded and the car would fire up instantly, when it was cold, the metals shrank and caused loose connection and no juice. I guess if you live in a climate that sees both very hot summers and cold winters, you should check every once in a while to be sure everything is still tight because of the varying tempurature extremes.
