2016 GMC Sierra

[karting007]

I have a GMC 2016 Sierra. Went to go someplace yesterday and the truck would not start. Getting a code PO23f. Is this a common issue with GMC's? Is it typically the module or the fuel pump?

Instead of just chucking parts why don't you check into it and see if there's power at the pump and go from there.
