Sounds like you have your culprit If it'll start in neutral and not park, it may be the switch. Try shifing to neutral, then back to park. PUSH the shifter forward toward park and hold it. See if it starts. I've seen where sometimes it is in park but the shifter is not fully hitting the safety switch. When this happend I hit the shifter forward and it moves it just enough to engage the switch and start. Sent from my SM-P600 using Tapatalk
