Ok, so we have been working on this a while. I had the serpentine belt break on an 08 aver LS that has 70k miles on it. We replaced the belt, but then the car wouldn't start. It cranks, but won't start. Here are the things we did to troubleshoot the issue:
1. checked the computer for codes.
2. checked the air intake filter
3. checked the spark pugs, are getting spark
4. tried starting by putting ether in the air intake, no start.
5. Removed the timing belt cover, the timing was off.
It looked like some of the serpentine belt made it into where the timing belt is. The timing belt was OK, but it was misaligned. We got a timing belt kit, replaced the pulleys, belt and water pump since we were in there. Everything seems to be in ok order... All of that is done, we attempted to start it tonight. It still won't start!
Any advice? Heeeelp!
