- the car, after driving into a puddle, has gone out and won't start

Hello,

yesterday, during heavy rain, it flooded the street, driving the car I drove into the flooded street, the water was reaching the car's threshold (the door could still be opened), after a while the car went out. The car was pulled out of the water in about 20 minutes (he did not want to start on his own). After being pulled out of the water, it was impossible to run it neither on the cables nor in the hall from a higher gear. Candles were checked on the spot - no water poured into them. When you try to turn on the lights, they are on, but the starter does not move at all. When trying to start from a higher gear in the tow, it jerked and broke the towing rope (someone suggested a starter lock?).
My question is where to start today checking why it does not fire (starter fuse, starter, engine, candles or something else) and what these symptoms can be described above.
Could the engine be sucking water by this moment?
Is there a cover for the front towbar on this version of the car?
Car details:
Ford Focus MK2 1.6 Petrol 2006

Thank you in advance for your help.

Hearing the fuel pump operating?
Asking about water in the exhaust, the catalyst flooded with water can become a pile of wet sand that now clogs the exhaust.

With such a deep puddle, the water most likely flooded the starter, here is the cause of the failure. However, this is the least of the problem. It is possible that water has got into the engine or gearbox. All this should be checked, and not "force" starting the engine, because it will lead to more serious failures and, of course, significant costs.

Since the engine did not want to turn in the hall, the water was sucked in. If you did not bend the connecting rods on this string, you are very lucky. Remove the spark plugs, run the engine a few times by hand. Check that there is no water in the oil. Then you can try to fire. But I think it's better for the mechanic to deal with it

well, think what force on the shaft must be.

Candles unscrewed, water was in the engine, it was "poured out". Earlier, the engine blocked, the starter did not turn - at the moment it turns the starter but does not want to start. There are no traces of water in the oil, no coolant escapes, nothing knocks when you try to start.
The air filter has also been cleaned and dried.
Is there anything else you can check? How long to wait for the residual water to evaporate (currently the weather is not good, it is raining, there is moisture)?

It can be said with high probability that the connecting rods are bent.

Compression is after this "action"?
Spark?

Other wonders could have happened there, such as a timing adjustment ...
