I pulled my 1999 GMC Sub into my garage to replace the water pump, I unplugged the battery cables and replaced the water pump. After doing so I replugged the cables to the battery and got absolutely no power, no under hood light, no instrument panel and no inginition. Had starter check, it's fine. Checked inginition switch harness, no power or ground to any pins. Battery is fine, check all grounds,had power at starter. Checked underhood fuse box and had to power or grounds.Is there a one stop shop for all powerfor the vehicle that I have not checked? Any help would be greatly appreciated!!!
