If you turn the key and get nothing, either there is a wiring issue, a bad starter, an issue with the park/neutral safety switch, or a power issue. Take a look through this link. It explains what to test when you have a starter not working.
Also, see if it will start when you place it in neutral. If it doesn't, we need to determine if or where the power loss is.
I pulled up the wiring schematic. There is a fusible link that may have failed. It powers the ignition switch.
I attached the wiring starting system wiring schematic below. Here is what I need you to do: First, there is a black heavy gauge wire direct from the battery. It should have 12v at all times. Confirm that.
If that is good, locate the thinner purple wire on the starter. That wire should have no voltage until the key is in the start position. Have a helper turn the key to the start position while you check for voltage to the purple wire.
If there is no power, either the fusible link has failed or there is an issue with the ignition switch. However, my guess is it would be the fusible link.
Let me know what you find or if you have other questions.
