Hello, my name is***** sounds like you either have a failure in the transmission module, or more commonly a failure in the transmission position sensor. When this sensor fails the computer cannot tell which gear you have put the transmission in. I would try putting it in neutral to see if it allows you to start it. If it does then it is bad. If not then the circuit will need to be tested with a voltage meter. A low battery can also cause this but that is not as common.
If you turn the key on and apply the brake pedal do you hear a clicking from the shifter? It will not move?
Have you checked to make sure that the battery is fine in the vehicle. If it is not above 10.5 volts then this will occur even if other circuits seem to work fine.
I would not waste money on a new battery without having the old one load tested first. If it is fine then the position sensor is the most likely issue.
It is the transmission position sensor on the transmission itself. I can see if I can get you the factory part number for it.
