You should check the signal wire at the starter to see if there is 12v when the key is turned to "start". This would require a voltmeter (preferred) or a test light (will tell you if you have voltage, but now how much) and may require a second person. If not it is likely that you have a bad ignition switch electrical portion, or possibly damage in the wiring to it (I have seen the wires crack from the steering column being adjusted up and down too much)
You can also try turning the key to on, and jumping power from the main cable at the starter (always battery voltage) to the signal terminal on the starter, and see if it starts. Make sure the vehicle is not in gear and parking brake is locked.
