Car ran fine one second. The next, not so much.

You can hear the starter but nothing happens? You have to explain that better. Does it crank the engine? Does it just make a single rather loud clunk each time you turn the ignition switch to "crank" but not crank the engine? Does the engine sound normal if it cranks or does it seem to be spinning too fast with little resistance?

I have to guess you have a 2.0L engine. When is the last time the timing belt was replaced?

The timing belt should have been replaced somewhere between 75,000 and 100,000 miles to prevent serious engine damage. All manufacturers recommend the time interval, but those are not always reliable. Honda used to recommend every 75,000 miles, and their timing belts commonly broke at 65,000 miles.

If you do have a 2.0L engine, that is an "interference" engine. That means when the timing belt breaks, the valves that are open will be hit and bent by the pistons as they coast to a stop. That turns a four or five-hour maintenance timing belt replacement into a real expensive valve job. The clue is the engine spinning too fast with little resistance when it's cranking. No compression can build up when the valves are leaking.

The first step is to remove the covers to inspect the timing belt. If it is indeed broken, we know it needs a new belt and a valve job. If it's not broken, it is possible some of the teeth have sheared off and the belt has jumped over the teeth on one of the sprockets. The result and the repair are the same but it takes a little more work to find that.
