The best suspect is the transmission range sensor. First, try shifting gears a few times, then try cranking the engine in "park', then in "neutral".
Next, look for the starter relay on the inner fender near the battery. Unplug the tan / red wire, then use a test light to check for voltage on that wire's terminal. You should find 12 volts when a helper turns the ignition switch to "crank". If you don't find that, suspect the range sensor.

You can use a digital voltmeter too, but for this type of problem, they can easily give false readings that will confuse the diagnosis. The test light can be more accurate.
