I have a 2014 gmc seirra and periodically when I'm driving my screen and dash will start flashing, radio cut in and out and if I try to accelerate I will get a reduced engine power warning. The code is P00CA for the Fuel Pressure Regulator High Control Circuit High Voltage. If I turn the vehicle off for 10 min the code clears and the vehicle operates fine. I have already taken it to 1 mechanic and they checked out the fuel pressure regulator and it was fine. They could not get the vehicle to get the screen or dash to flash so I assumed the issue was fixed but it started doing it again 3 weeks later. I have read many issues about bad grounds but those seem to be linked to power steering not the fuel pressure regulator. Has anyone else experienced this issue?
