This code would mean wiring/connector, injector, or fuel injector control module in that order. I'd expect repair to be around $1000 at a shop depending on where you go and what the problem is. My goal is to provide 5 star service so please let me know if you have any questions, thanks.

this aint a DIY job?
GMC Mechanic: Dan, Technician replied 3 months ago

You could do a visual inspecting or wires. Common places for wiring problems are near EGR tube, near fuel injection control module, and alternator bracket. Beyond that a shop may be the better option but you could do everything other then injector control module if you were determined. Let me know if you have more questions, thanks.
