1998 Jeep Cherokee Won't start

My 98 Cherokee won't start. I started it the other day and moved it to the driveway, and when I went to get back in it later, it won't start, not even a click of the starter. Battery is fine, starter connections are fine. Won't turn over in neutral or any other. I have radio and lights and guages, but that won't get me to work. I keep getting mixed messages online. Throttle sensor, or crankshaft position sensor. I have no clue.
