P0090: Fuel pressure regulator control circuit open
P00C8: Fuel pressure regulator solenoid supply voltage control circuit open

I'd start by checking the connection to the fuel pressure regulator.

Then, if the issue continues, I'd replace the fuel pressure regulator.

Then, if the issue continues, I'd trace fuel pressure regulator wires to wherever they go to look for a physical problem.
