You may also want to check the distributor drive gear. They're plastic and it's common for them to break. Just pop off the distributor cap, ground the distributor end of the coil wire, and turn the engine over to see if it also turns. You can also just try turning the rotor by hand too, but, don't crank on it too hard! If you can spin the rotor by hand, or, it doesn't turn when you crank the engine, you have a broken gear.
