car help change fuel pump and battery and car is no longer turning over at all?

[k1e2m3o]

so i was driving my car downtown parked it and ran into a store came back it wouldnt start. My mechanic friend came told me my fuel pump wasnt kicking on after banging it witha hammer got it working again.... So we fixed that. Then when i was drivng home the same dayi turned a corner and the whole car stopped and locked up like it was out of gas. so i got it home we put more gas in it. but he car wouldnt crank back up it was turning over but nothing. So we thought maybe all the cranking killed the batttery so i went and got a new one. once i put it in the car wouldnt do anything anymore.all the lights come on bright and strong but nothing else happens. and i think there a faint click when i turn the key
