Man...running a tank dry can completely fuck any EFI car. You could have some wicked vapor lock or you could have cavitated the pump. The big problem with in-tank pumps is that when you run below a 1/4 of a tank or so, the pumps start to heat up since they rely on the gas to cool them. When you run the tank dry it just causes more problems. I don't think it's the PCV valve (although it might be a good idea to change that anyway since they cost less than $10), especially since the problem only started after running the tank dry. I'm willing to bet it's fuel related.
