Hello, I Own a 2009 Sierra 1500 5.3 L. I was driving the truck fine on the way to work, I was low on fuel and planned to fill up after work. After I finished for the day the truck wouldn't start. It would turn over but not start. It gave me a P1682 engine code. I put a brand-new battery in about a month ago. I have checked to make sure battery terminals are tight, and I've checked all fuses in the fuse box. I tried moving the powertrain relay to the crank(seen this on youtube) no luck with that. Also after the truck is in the on position for a couple of minutes a reduced power engine code comes up. Not sure if anyone has had a similar problem. Any help would be great!!!
