timing belt on 2000 Saturn LS2

The timing belt snapped - we replaced it along with tensioners, pulleys & water pump. The car will not start, compression check revealed 3 cylinders were low 50-75-75 the others were all @ 125. There is spark but it won't fire up, fuel pressure seems ok. It ran fine before. ?????

sounds like you had the teeth off a bit when you changed the timing belt. possibly bent valves and timing issues now
