I have a 2012 Chevy Cruze 1.8L that just rolled over 100k miles, yay! So I got a great message everytime I got in it saying timing belt needed replaced, no big deal scheduled maintenances are a thing. Screw up no. 1, thinking I could replace it myself even though I don?t have a special cam locking tool, screw up no. 2 replacing it myself with no special cam locking tool. I watched some videos and thought hey I can do that, stripped it down and pulled the old timing belt off and made real sure to not let the cams or crank rotate and put the new one on, done deal right? Nope I was a couple teeth off and it was an easy adjustment to pop the belt off and set the crank back a couple of teeth so when I put the belt back on I could turn the crank to get the slack out of the belt. Now my timing marks are aligned. I cannot get my car to start, it turns over but won?t fire, I?ve checked fuses and the battery, it seems like the crank is weak, I know my cams are still aligned because I pulled the valve cover and double checked with some cam marks someone left with a marker (presumably the factory) I don?t know if the sensors are out of whack or what but my main concern right now is that I don?t think I screwed up any valves or what, I believe the issue to be timing and I?m just at a loss on how if everything was on marks, I went 180 out on my cams to make sure i wasn?t 180 from putting the new belt on and maybe one slipped and that didn?t work so I went 180 again to put it where it was originally or so I believe, I lined up top dead center by lining up my markings and everything, I?m just at a loss and feel like I?m missing something obvious, can anyone help an idiot out?
