timing issues

What is your question?

I have a 2000 Jetta 2.0, I bought the vehicle not running. After pulling the timing belt cover I found that the nut holding the timing belt tensioner was missing, therefore no tension on the belt. I have fixed the belt and replaced the camshaft sensor (only because it was the code when I read the OBD), after doing so it still won't start. I've re-timed the vehicle several times and don't think that is the problem. I'm getting spark, and I can smell the fuel. Don't know where I'm going wrong here, any help would be greatly appreciated!
