Default Throttle Body Wiring with P Codes / Electrical Prob with Fuel Pump

I am getting a P2100, P1290, P2101 code. Looking at the wiring diagram it seems to show something labeled as NCA (google searches suggest "No Color Available") diagram shows dotted line around the wires from the harness connected to BLK going to Ground. Can anybody explain this notation?
Additionally, Fuel Pump not getting power signal from the IPDM - voltage at all the correct spots, but CPU inside the IPDM not completing the ground to allow the fuelpump relay to energize. Attached screen snap of Throttle body wiring and Fuel Pump Circuit.
