Help Please!

My battary died and i jumped it. Drove it and stop at a walgreens and it started and I put in in reverse and then it died. Tried to restart it and it won't crank over. Put a new battery in and it lights up, and the fual pump kicks on but it won't crank over. what do i do?

 

Well, this is Cars 101; but I would take off both ends of each battery cable, clean them and their bolts and nuts well, and reconnect them firmly before doing anything else. Often, even when jump starting, that is the problem -- and it's cheap to try first.
