NP Ed; sometimes details gets missed in a long post
honestly the car was cranking in the beginning, then it started to not crank anymore: click and that sound that you get when you wanna crank a car with a battery that is almost dead (no idea how to explain; just put the slowmo to the regular cranking sound and just for one or 2 seconds and you get the kind of sound that i get

).
The particular thing is that if i turn off the car and try to crank again, it won't crank, but if i leave the key in the on position for a bit, it is like "something" is loading up electricity and then try to release it, making the cranking faster, but still not enough to start the car (again, same slowmo cranking noise but this time last longer; not that much thou).
At this point the first attempt will be to replace the solenoid (hopefully i can find it locally; otherwise is a real PITA); maybe is just old and has to be changed....I've got the car from another person and i have no clue of what was changed by the previous owner(s)...I am just being a good citizen doing the work that has to be done, changing oil and filters at right mileage and fixing one thing at time (of course if ain't broken leave it as is until it breaks); i have no clue when was last time taht the compression and the timing was done; I've ran with the car for almost 5K so probably in a bit i will do it.
Indeed the car was under the rain, but it was not left under the rain; I was driving it from home to work and back (5 miles one way), so the water that the car has got is basically the one that could slip in while driving under the rain;but i will check the distributor cap to see if there is any condensation; there should not since the car was working fine until this weekend, and the last time that it was raining was a couple of weeks ago, if not almost a month ago; but is worth the try; I would exclude thou water in the alternator, otherwise every 911 owner would not drive at all under light rain...but again you never know, and at this point is worth the try.
At least I have some things to check first thing in the morning tomorrow; maybe is just something stupid
