you replaced the fuel pump or a shop did ? Sounds like the pump primes the system but doesn't supply fuel once it's running , there may be 2 relays one for for each function , it needs a good ground too , could be a wiring problem these things need to be diagnosed instead of just replacing parts , unless that's your thing
