Fuel issue

[B7rs4.2]

Hi all new to the forum !

HELP REQUIRED

I DID A FULL ENGINE SWAP ON MY 2007 b7 rs4 4.2
After the build car started on idle no problems then went to drive engine light comes on the fault code is p0190 I replaced the G247 sensor fuel filter and the fuel pump and sender located in the tank the fault cleared and and fault code p0023 appeared I replaced the exhaust cam sensors and also the cam position sensors message was "B" camshaft position actuator /open bank 2 this fault then cleared and now p0190 has returned message is fuel rail pressure sensor "A" circuit

HAS ANYONE ELSE EXPERIENCED THIS PROBLEM OR SIMILAR
