If you have a voltmeter, we need to do some testing to see why this will not start.

6. NOTICE: Do not drive the manual control shaft pin through the manual control shaft. The manual control shaft pin will contact the transmission case causing damage to the transmission case.
NOTE: If the roll pin remover does not pull the roll pin far enough to clear the manual shaft, the roll pin can be pulled from the TR (transmission range) sensor with a pair of channel locks.

Using the roll pin remover, remove and discard the TR (transmission range) sensor roll pin.
