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.

Yeah, it takes sensor signals from the camshaft position sensor and both crank position sensors and sends them to the ignition control module and then the PCM to determine ignition timing. If one of those is unplugged, you won't get any spark initiated at all and the engine won't start. :)
