Won't start, intermittent fuel pressure, wonder if fuel

Customer Question
Won't start, intermittent fuel...

Won't start, intermittent fuel pressure, wonder if fuel volume/pressure sensor is bad. computer code P0001.

Mechanic's Assistant: Are you certain it's the fuel pressure sensor that's in need of attention? What about the fuel rail? Have you checked it yet?

No, I just found that sometimes there is good fuel flow to the rail, and sometimes not. The fuel pump does not always turn on when key is turned.

Mechanic's Assistant: What is the model/year of your GM?

2007 GMC Acasia

Mechanic's Assistant: Are you fixing your Acadia yourself? What have you tried so far?

I'm trying to fix it, I usually fix all my own cars. I have checked for fuel pressure at the rail supply from the tank. When key is switched on, fuel flow is intermittent.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Can he tell me where the fuel volume control regulator & circuit is located? I want to check for an open circuit there as per the DTC code p0001

P0001 is not a valid trouble code for a 2007 Acadia. Can you double check that?

After i first viewed the code, I then erased it to see if it would come up again, and it did. My code reader said" P0001 Fuel volume regulator control circuit open".
