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.

Do you have 12 volts at the connector for the coil with the key in the on position?

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.
