how to figure if ur fuel pump is getting electric? on 1995 Buick Riviera

my fuel pump started humming while driving and car did not want to accelerate here and then and then fuel pump died put a used one in and would not turn on and no fuel pressure and then got another used one and it dont turn on either. would it just be bad luck of buying two bad fuel pumps or not getting electric fuel relay and fuel fuse are brand new
