1998 dodge stratus

I have a 1998 dodge stratus 2.4 L DOHC I just bought it I gentleman said all it needed was a timing belt. I changed the timing belt and all other belts also. when I try to start it, the car still wont start what could be wrong.

[it could be coil pack could b crank censor could b alot of things did u make sure it was put in time right

I made a video on youtube for this engine on how to put the belt on.
my youtube is also stingray4me. If you have it one tooth off it will still run & drive ok, but it will shake bad while in netural or drive Cant remember which one, it feels like a bad motor mount.
