Check for your sunroof drain hole.. it could be cloge.. look around on top are and in back where the sunroof seat ... you should used a strong gauge wire to unplug the drain some people use cable tv it stronger and work better.. some use air compressor to clear the drain..

but that what causing it..

as for your gas smell opend up the hook and check around near your injector rail... for gas line leak.. it is a ruber hose that have a crack ...

it happend to me last year.. .. but let the engine when you check so you can see the leak.. take your time you will fine the problem..
