If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.
Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.
The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.
