Here we go again, why don't you just rent a fuel pressure gauge from the local auto parts store and check the fuel rail pressure. Just turning the key to the run position will initialize the fuel pump and you should be able to get a fuel pressure reading even if the engine doesn't start.

You could also have to bad coils. Swap them out with coils 5 and 6 and see if the misfire don't move to cylinders 5 and 6.
