6.6l gas truck would not start. Forums ive visited state this is a known problem with the ECM. After approx 30mins it started. However before that it sputtered out every time I would try to start it. It appears to be an intermittent problem. It ran fine once it eventually did start. Also auto start wouldn't engage when this problem was occurring.
