First try it in "neutral". If that works, suspect the neutral safety switch/range sensor.
Check the battery's voltage with a digital voltmeter. If it is good and fully-charged, it will read 12.6 volts. If you find it is near 12.2 volts, it is good but discharged. Charge it at a slow rate for an hour, then try it. If you find it is around 11 volts or less, it has a shorted cell and must be replaced.
I will figure out where to go next based on what you find up to this point. A test light will work best for the next tests.
