Hello and welcome to JustAnswer!

It sounds as if the problem has been diagnosed as the fuel pump? If there is no fuel pressure yet the engine controller is awake and there are no fault code then the fuel pump power and ground feeds would be tested. If there is power and ground at the pump yet it does not run, or it runs but does not create enough pressure to start the engine, then the pump will need to be replaced.
