Thank's for all your inputs!!!
Well, it looks like the power comming through the ignition switch is there. The red (hot at any time) is also there. Nothing comes through the main relay! But I thought the main ralay is operated by the ecu, is not it?
The camshaft sensor was dried. After that I could start the car (after drying spark plugs, changing oil, and the air filter) and move it to my place (about 300 meters). It ran like crap, of course, since the ecu got water (which I had no idea about at that point). After that it never started again... no sparks.
What's interesting, twice, when I connected the batery to try srating the engine, some weird sound came from under the hood. I could not locate it but my best estimate was somewhere benith the ignitor. It sounded like shortened wires sprking... The brain at that point was still full of water, btw...
Guess, the bottom line is don't be as stupid as I was and don't run into water deeper than one foot. :-\
