If it's cranking, your problem isn't timing. The symptoms of timing being off are, running like crap if it's 1 tooth off, and the pistons kissing the valves if it's 2 teeth off.

Start with the basics - is it getting fuel/air, is it getting spark, does it have compression.

Wait a second - the timing wasn't being done because the belt had let go, was it?

I have not tried that, I will have to try that today
Just to clarify: rotating twice around is not some kind of fix, it is done to make sure that every thing is working properly. If you can go twice around by hand and the timing marks end up exactly as when you started, it should be good to go. You always want to perform this check when timing one of these interference engines.
It rotates twice around and everything lines up how it did previously, but still will not start.

manual rotation is done before turning the ignition key.
You already tried to start it without checking for valve clearance.
Valves could be crashed already.
Or it could be something silly simple.
A quick compression check would help eliminate the possible catastrophe.
