The first check is the fuses. See your glovebox owner's manual for info. Blown fuse means something is wrong. But change it with a correct amperage one and see if it holds when you start the engine. If all works, great. Might have been a flukey problem. But carry spare fuses with you at all times.
If there's no blown fuses: I'd get at the easiest spark plug wire you can reach, and pull it. Put a good spark plug into the boot, and crank over the engine and see if you have a spark there (touch the ground electrode of the spark plug to a bare metal spot on the engine). That's to confirm if the ignition module is putting out. If not, check for power coming to the module. If there is, the module is suspect. If there is no power, then the ignition switch is suspect, even though the fuel pump gets power and the engine cranks.
These ideas are just to help you get started with the troubleshooting, and are general in nature.
