2007 chevy silveado 5.3 12000 miles on it Started
Is this a 1500 Silverado? I looked at my database, didn't see pcmb fuse? These databases are not always correct. On some gm makes and models, the pcmb fuse supplies voltage to both the pcm and fuel pump. Unplug the fuel pump, see if fuse still blows? If it does, it's not the fuel pump. Can't rule out wiring circuits? Has this vehicle sat for a long time?
