I would suspect that is immobilizer related most likley, although it could possibly also be the ecu not getting reconizable inputs from other systems which are required to start.Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle
