Hello. Welcome to Just Answer. Please allow me to assist you. There are two things that can cause this: timing belt or the water. Water ingestion inside the cylinders is most likely the issue. If the car is running on cylinders 1 and 2, the igniter and the rest of the electronic system is OK. I would recommend you have the compressions check on cylinders 3 and 4. If the compressions are very low, you either have piston issues or valve issue. It is possible that the timing belt has jumped, throwing the cam timing off to allow proper placement of the valves for combustion on cyls 3 and 4. Set the crank pulley on TDC and pull the distributor cap off. The end of the rotor needs to be under the section of the cap that is connected to #1 cylinder. If that is where the rotor is, I suspect valve or piston issues.
