I am looking for someone to help me get my 2018 5.3 with 6L80 out of a Silverado running in my 1957 Chevy wagon. I have reworked the wiring harness and had Current Performance program the computer. I used the fuel pump and module out of the Silverado and reworked it to fit in my new 57 wagon fuel tank. I also installed the fuel pressure sensor in the gas line along the frame. Everything is wired correctly but I cannot get the fuel pump module to send power to the fuel pump. I can disconnect the module and jumper the power wires and the fuel pump will run but the engine still will not start. I am reading three abnormal codes with my tester, they are P0073 Ambient temperature sensor high voltage, P018C Fuel pressure sensor circuit low voltage and P12A6 Fuel pump driver control module enable circuit performance. Anyone with experience with this can please contact me. Thanks Mick
