Are you saying you replaced the fuel pump? Did you test it to determine it wasn't working? There's several reasons a fuel pump fails to deliver fuel to the engine. You need to fully diagnose the problem.
1) Does fuel pump work?
2) Does fuel pump get 12v?
3) Does fuel pump deliver regulated fuel pressure to rail?
