Check the Fuel Pump Control Module for good power and ground before replacing. After replacing, the module will need to be programmed with SPS2.

Which module set the P062F?
The only time I've seen that code was on a '12 Acadia that had a no crank complaint. P062F was set along with a list of O2 codes:
I ultimately found a failing battery. Cranking voltage would go below 6V at times. Voltage drops were good. TSB #12-06-04-001 suggested the same:
I'd monitor PCM powers and grounds during the shutdown, if you haven't already. Don't know the mileage, but a 2012 is old enough to have had the engine out at least once for chains. That makes the main block ground, the rear cylinder head ground and the fuse box connections suspect. If the powers and grounds check, it's ECM time.
