your motive for washing the engine?
did you read it in a magazine?
peer pressure?
did a hot model tell you to?
had a dream where a fairy told you to?
I never have heard of anything that starts with - "I started randomnly drowing parts of my car's engine bay with gallons of water" unless one of the above was true or there was some hallucinating drugs involved.
btw - your engine didnt start, the starter was pulling the car itself because it was in gear (please note that your parking brake/handbrake is bad too).
I would suggest you check the starter itself for amp draw now, anytime a starter is let to crank for more than 20 seconds it gets damaged.
