By Flooded do you mean with gas or was the car submerged in water and is now hydro-locked? If its hydro-locked it can run again but is not an easy fix. First drain the oil and any water that's in the crank. then put some oil in and remember to change the filter as well . Next remove the plugs and crank the motor to remove the water from cylinders.replace the plugs and spray wd40 on all wires and electrical connections as this will help in drying out the contacts and keep things from corroding, a hair dryer helps speed drying. Make sure your air system is dry removing old air filter and checking air intake for water. Check your fuel tank to see if there's water in the tank,replace it if needed. Now you can try starting the car. There could be damage to the ECM if its not sealed well and your fuse panel can also cause issue. If your willing to take the time it can run again. If you were talking flooded with gas let the car sit for an hour and try again if you have no Joy then pull the plugs blow out the cylinders with compressed air dry off the plugs and reinstall . Good Luck
