After I put the key in the ignition, both the "P" and "D" light lights up. The car won't start up or crank up at all. Once the key is turned, the indicator light "P" or "D" no longer lights up. Could this be an electrical issue making the computer think the car is in "D" thus won't start the car? I can change gear and put the car in "N" or "D" and is able to push the car back and forth.
