dead short bank 2 got a problem with a 2000 silverado but figured cars may have same problem and need help what to do next. soon as i put a fuse in bank #2 it blows it. checked fuse block for short and looks visibly fine. i have unplugged coils and injectors to eliminate short there so what next ? harness looks fine but i haven't unplugged it completely to examine it.any help greatly appreciated.

Sorry to say, check it wire by wire. Something could be chafing through worn insulation.

You can begin by disconnecting the #2 bank small harness at it’s origin (toward computer), then insert fuse. If the problem goes away, then reconnect small harness, then manually separate the small harness wires, beginning with cyl #2, then insert fuse. Then cyl#4...... Best of luck!
