Low fuel pressure

Having low fuel pressure on 08 ms3 the car will start run for 5 secs then die fuel pressure reads 130psi and that’s it. New Fuel rail / sensor , new hpfp housing and internals , relief valve , spill valve , in tank fuel pump , Seals and fittings , injectors all been replaced brand new wiring harness as well. Car was just built and everything on the motor was just replaced with oem or aftermarket. Any body know what could be cause the fuel pressure to be so low
