After I have done this I put the 5.7 computer in and my fuel pump will not come on now and I had no fuel pump problems before, when I power the pump the car will turn over but will not run.

you can i swapped my 4.3 out for a 5.7 for a while but changed it back over for the time being. never had a fuel issue with swapping computers.
