No crank no start?

At the beginning how are you all?
I'm from Yemen and nobody has any knowledge about BMW's.
I faced this issue after the bottle of the radiator was broke during replacing A/C compressor.
And the water comes out under the hood while driving.
Then issues of the light brake and taillight always activate till I press start button several times or inserting the fob key several times then issue of no crank no start appears after days no problem first start but after driving and switching of the engine nothing only clicking and sound from rear Fusebox and down the steering and sometimes airbag lights and the wipers don't stop and driving stability.
Sometimes disconnecting battery terminal sometimes help to crank and start and sometimes till it cooled
I hope that I explained my headache and crazy problem properly.
Thank you all.
