150 Suzuki 4 stroke won't start

[pjayswell]

This is a 2006 engine with 185 hrs, and it has been well maintained. The tank got water in it and the engine quit. The water issue is being resolved but I bought a 6 gallon tank and new hose to be able to ride now.
The fuel is new as is the tank but it won't start . I am not a mechanic, but i am inclined. Can anyone give me advice where to start. I did remove the injectors and drained the fuel rail and let it dry out. Still won't start. Any ideas?
