2009 Sierra crank no start
Hey, so I’ve got a 2009 Sierra 6.2 Denali and it cranks but doesn’t start. It has two main codes
U0 109 and p0230. I dont have power to fuse #20 (fuel pump) thought maybe was my fuse box
so replaced that but still no power to that fuse. I have by passed the FPCM as well to test the fuel pump and it does work any ideas ?
