There are several things that can cause this so you may need to have it towed to a shop to resolve it.
Here are a couple of things to try. Make sure the the fuel shut off switch has not been tripped. Check your owner's manual to find it. I think it is on the driver's kick panel. Try depressing the button. If it has been tripped, you can feel the button click into place when you push it down.
In the rare event that you flooded the engine, try cranking the engine with the throttle held fully open. This shuts off the injectors. If the engine is flooded, this will clear the cylinders and it may start and run rough for a moment untill the plugs clean up. This can happen from running the engine for a short time before shutting it off, such as moving the car out of the garage to get the lawnmower out.
