Is a fuel pump outta a 4.3 s10 compatible to a 2.8 s10 tbi?

What is your question?

I gotta prime the throttle body and it will fire but to keep it even remotely runnimg i gotta pump the hell outta gas pedal and all it wants to do is spit and spudder. Its getting fuel to the throttle body all my lines are right no leaks anymore i was told change the throttle position sensor. Anyone ever have the same problem? Evrything seems to go fine until i try and fire it up its a 93 tbi 5 speed single cab 2wd id appreciate it if someone can get back to me its the only ride i got and a family and job so i gotta have wheels. Thanks in advance.. Like i said pump works sending unit pushes gas to motor i got spark but will not stay running it fires spits and spudders and dies
