Well, that could certainly screw up the air calibration and cause your detonation problems....doubt that it had anything to do with the refusal to start, tho.
Does it sound like it is trying to crank properly? (wondering about timing chain)
Sounds like it may have spark.....try spraying some wd-40 in the tb and see if it tries to run? Got fuel pressure?
I just go down the list, spark, fuel, etc as Jim listed.
