I have a 2007 with 47000 miles and it has a starting issue. I had it checked and they said the battery was bad. I replaced it and still the same problem. Sometimes it starts right off then other times it cranks but doesn't start but fires up on the second attempt. The chevy house said that they would have to test it. Has anyone experienced this and had it resolved? I've heard fuel pump, computer that not fixable, new switch but I really not interested in being a test case at a $100 hr.
