Hi,
Do you have a live data scan tool? If you do, check to see what the coolant temp sensor signal is to the PCM. If it is indicating extreme cold temperatures (for example -40F) the computer will cause the injectors to stay open longer to allow the engine to run in those conditions. If it is actually 70F, it will flood the engine.
However, if the plugs are getting wet immediately when the key is first turned on (without cranking), then we need to test fuel pressure to confirm it isn't too high and the injectors are good.
If you haven't checked the pressure, you should, it could have a faulty regulator. Here is a link that explains how it's done:

Also, here is a link that explains how to test injectors:

I have one other thought. Have you checked to make sure the plugs are getting spark? I ask because if they aren't burning the fuel, they certainly get wet. Here is a link that explains how to check.

Let me know your thoughts and what has been done as far as these tests.
Take care,
