I hadn't had a chance to get to the car until today. I tried push starting the car and it started right up, but I wouldn't think that would eliminate the starter or ignition necessarily...any opinions? thanks

It is probably your starter then. However, put a test light on your starter while someone turns the key over and see if you are getting power to the starter. It could just be a connection there.

I remember on my old formula, the rear main was leaking and it caused the starter to go bad. I ended up fixing that in order to keep from replacing my starter every few weeks.

Clicking when starting is not enough current thru the circuit. There are many reasons for not enough current. The most often reason is a bad connection causing too much resistance to overcome. The second most often reason is a low/or bad battery. Remember that the colder it gets, the lower the output from a battery. When you put a cold battery with a poor connection, it will get you every time.

The last most common reason for not enough current is a defective starter that "pulls" too much current. As starter windings deteriorate and begin to short together, the total resistance of the winding becomes lower and eventually draws more current then the battery provides. Couple with old connections and the problem is worse.

To rule out connections, use a jumper cable to jump directly from the positive post of the battery to the starter post. Remove the coil wire so it won't start. If that doesn't cure the problem, run a seperate jumper from the negative post to the outside of the starter and try the positive jumper again. This will eliminate the posibility that it is a bad ground.

If that doesn't find the problem, have the battery load tested and be sure the battery is rated over 650 CCA.

With a KNOWN good battery directly jumped to the starter doesn't cure the problem. Then it's the starter.
