Hummer H3 2006 235000 miles
Went up a hill one night and car made a weird revving sound and died. I was able to start it after 4 to 5 min and went 5 min home. The next morning I cranked it and it started. I put it in drive and it died. Has only cranked sence but no start. Codes say exhaust CMP sensor but that has been replaced as well as pigtail connector but still will not start. No other codes.
