i tried to start my car and it wouldnt start, it would try but it just couldnt do it, it happened earlier in the day but then started but this time it wont and i had a leak under the car but cant really tell what it is... what could the problem be?

 

Make sure your battery connections are tight, secure and clean.

 

That and need a lot more info eg: color of fluid, turns over but does not start, click when i try to start

 

it turns over but it wont start the fluid was light it didnt smell like gas and i cleaned the floor its not leaking anymore.
