you should test things before replacing them , you need to test for proper fuel pressure and spark some vehicles are particular just having them won't do , , and see if the injectors are firing
Mine was doing the same thing. I changed out fuel pump relay and had diagnostic run on it and it pulled a code for cat converter and O2 sensors. Also the battery was drained down to a 31% charge due to months of crank, no starts. It also threw a code for throttle actuator control module. Replaced battery, catalytic converter, O2 sensors and module for throttle body and no problems now
We tested for fuel pump and injectors using starter fluid in the breather and it cranked right up so we eliminated fuel pump relay, fuel pump and injectors then ran a diagnostic
