Sonata Hard Starts then Pings then No Problem

Hello All,
I'm hoping I might get some thoughts from you concerning a strange
problem that occured with my 2004 Sonata V-6 this morning (68 k
Miles). I went out to start my car this morning, gave it a crank and
it did not want to turn over. I tried again and actually tried giving
it gas at the same time and the car did in fact start. All this is
very out of the ordinary as I have never had this problem before. The
strange thing was that once it was started, there was a very loud
clicking noise as the car ran coming from under the hood. It almost
sounded as if there was no oil in it or perhaps some sort of a belt
sound. The strangest thing is that I shut the car off and started it
again and everything was back to normal. Specifically, the car
started up fine and ran fine after this initial occurence. I have
started my car at least 10 times since this happened and driven it and
no problems at all. Do you folks have any thoughts as to what might
have caused this. Is it a matter of time until something
spontaneously combusts here? If so, any ideas what that might be?

Thanks so much,

 

Perhaps your battery was low, causing the slow crank and a problem with
the
engine management system.
