After filling my car up with gas it would not start. What should I check first?

What is your question?

The car turns over but does not start. The car sat for a full day and I noticed gas leaking on passenger side rear, where you put gas in the car. MBenz told me that both my pumps went out (yea, at the same time). I don't believe that. Is it possible that a relay went out or the fuse on a relay went out? Is there a overflow of some type that will release gas at the rear of that vehicle in the event that to much gas is put in the car?
