The ignition is cranking but wont start. And I have no spark at any of the plugs. The above items have already been checked... Thinking it may be a ignition cylinder issue?

i would start with a compression test to verify timing belt is ok.

does the check engine light come on??

I would re verify all fuses with a test light to make sure there is not one that has failed.

try this chart to follow for no spark. as you can see, you need a scan tool. it may be difficult but check the power to the coils first.
