You need to do testing, yourself. I don't know who told you to replace fuel pump? Did they do any testing? How long since a tune-up? Any applicable trouble codes? If you suspect a fuel issue, use a gage and check proper fuel pressure, engine cranking. If no pressure, check proper voltage and ground at the fuel pump connector? Just curious, are you missing anything else besides fuel? Engine cranking, do you have spark at the plugs and fuel injector pulse?

Like I said, check voltage and ground at fuel pump connector. The initial fuel prime, key on engine off, the fuel pump runs for a couple seconds, if nothing, check voltage and ground at fuel pump connector, if that is good and no fuel pump action, You may have to suspect the pump, certainly try to be sure before replacing anything. Just my opinion.
