How can I get water out of my gas tank? My six year old put water in the tank and my car won't start.

If it was only a teaspoon full or so, then the easiest is to go get some gas line antifreeze and put it in. If it is a lot? Then the ONLY solution is to drop the tank and drain and clean it out completely. If this bothers you then have the car towed to a garage equipped to do the job properly. Now, if you tried to start the car, BIG MISTAKE then you are probably in for a hugh repair bill for cleaning the entire fuel system. Injectors do not like water, and could possible also need replacing
