I have a 2008 silverado,1500, 4 WD, replaced the O2 sensor bank 2 sensor 2, (I was getting a P0056 code) it wore through the insulation rubbing on the frame. I NOW have a problem with the fscm fuse popping. Can someone let me know where the fuel system monitor is on my truck? Has anyone had a similiar problem? pulling what's left of my hair out.........
