To add some context and details, my 2004 Kia Optima LX was in the street when it flooded. Water line at its highest was just over the front right wheel hub and the lowest at its rear left wheel lowest lug nut. Water got inside the caving and made pools of water in all foot wells and was as high as just below the pedals. I made the mistake of trying to start it while still in water and it would turn over and not start. After letting it dry out and pushing it into the front yard with higher ground it wouldn’t even turn over. After looking at spark plugs, Ching the starter motor and checking every fuse in the car and even clearing a small amount of gas from the air filter. We have gotten the car to be able to turn over once again but it will not start. We believe the car is getting airflow, fuel is getting to the engine and the spark plugs are sparking, the engine will not actually start. One thing we have noticed is where in the gauge cluster where the semi automatic gears would show up 1,2,3,4 when the key is in the on position it shows an E. We haven’t been able to figure out what that means or what could be wrong with the car. We have a suspicion that a large vehicle in the neighborhood might have sent a wave into the car and got water where we wouldn’t have thought it would’ve gone with the water level. If anyone can give some further insight on what could be an issue or things we should try it would be much appreciated.
