Hi! a buddy of mine has a 1999 Grand am GT 3.4L engine that had a broken cam shaft. this weekend we tackled it and got it replaced. we put everything back together and made sure the timeing was exactly how we took it off and now it wont start.. it cranks over but wont start.. almost seems flooded is it possible it could be timeing though? any help would be appreciated.
