Back to work and still no car. Im going thorough the electrical system tonight and testing every connector related to the ignition system. By using the diagram above it leads me to believe that the short is before the ignition relay.

I don't have power at the ignition relay so the short pre-ignitor but thanks for the idea. That and its unlikely that both ignitors go out at the same time. Anyways the car will run on 4 cylindars. But thanks for the input. It's either a short in the wiring or a bad ecu. Time will tell.

I had the same issue this morning. I know its not ignition because 1 side can run without the other. When the car is running i was getting a loud humming noise that sounded like my fuel pump. Do pumps just die randomly?
