So I went through your problem exactly and I'm ******* thrilled to have fixed it I went through 3000$$ trying to fix it and what it was for mine was the PCM cover needs shorter screws it creates a short in the system get 6 4mm washers 3 for both screw and place them on the PCM the two screws can be located below the wiring plug ins if you want to see if you have a short in your system check the ignition coil for 5 or more ohms of resistance if you have less you have a short to ground. Hope it helps
