Hello,
Having water in the fuel tank will cause the engine not to run properly. If the water is excessive amount, adding fuel treatment won't fix it.
The best option would be to drain the fuel tank of all its contents. Then fill with good gas and run with fuel treatment to clean out water in the lines.
Here is a helpful video on how to get fuel out of the tank:

Let me know of any questions.
Thank you.
