Could be a number of things. I think I would try to narrow it down by feeding it with carb cleaner. Put about a tablespoon of gasoline down its throat and have a helper try to start it. If it tries to start feed it with the carb cleaner (spray can) through the throttle body. If you can keep it running with that, it will likely be a fuel system problem as opposed to ignition.

If no luck there I would pull the codes and see if something turns up.

Hope this helps,

really need to do more testing check fuel pressure, injector pulse and spark at more than one plug wire even if its just on the easy to get to side check for spark on several different cylinders you will probably find that one of the above is missing.
I know you said that you checked the ignition module but if it is not grounded good to the intake it will cause weird problems even a no start, or only spark on a couple of cylinders, so if you find you do not have spark on all cylinders you may want to remove the module and clean the mating surfaces put a slight coat of dielectric grease on it and reinstall it for a starting point.
