Check in the front catalayzer under is a oxigen sensor harness is usuly shorted for the heat of the catalyser is a commun problem with this engins. This shorted harnes will stop the car from running the pcm shotsdow power to that sector of the circuit for protection you obd2 scanner will say no comunication with the ecm/pcm . if this is you problem you shut fix the short harness after you have to relearn you key ,insert the key in the ignition switch turn to on waith for security ligth to stop blinking repeat this 3 times it takes obout 30 minutes make sure you battery is fully charge after that you key is relearn and you can start you car. I hope this help someone.
