Flooded Rzr 800 S

Buddy of mine rolled his rzr into a lake and we are about to start trying to diagnose the problems. Already drained everything and changed all the fluids and plugs. Only real issue is it doesn’t want to idle. It has a fuel controller on it and I am wondering if it could be ruined from the flood? Any other ideas would be appreciated.
