The car died while we were driving. We suspect Alternator. We got a new alternator and had that and the old one tested. The new one showed "Good" and the other one couldn't get a good read (so bad?) After installing, the car still won't start. It would turn over and die. Sometimes, it will turn over, start, then die. What's the deal? I even tried jumping it with the other car and it is still not working. What else could be wrong? Sometimes I can smell gasoline though.. Can anyone walk me through steps to diagnose? I used a bluetooth OBD to check for codes stored in the ECU but there isn't any.
