Default Blown Ignition Fuse

New member. Was searching the forum to get help on a problem I am having with my car. Couldn't find any similar posts.

67 Camaro with an LS. The car runs terrific, and I've never had any major issues until this weekend. Had to get it towed home, like the walk of shame.

Driving the car all day Sunday without issue. All of a sudden, it just dies. Cranks but won't start. Fuel at the rail, so I investigate ignition. Plug my scanner in to find a code. The scanner won't connect to the computer (GM ECM). Start checking fuses, the ignition fuse is blown. Replace it with another, and it blows immediately. Check my ground wires, all look secure. Look for loose wires that could be causing a short. Find nothing. Have been driving the car all over the place for five months without touching anything.

I;m at a loss. Need some ideas on what to troubleshoot next. I need to fix it and figure out what caused it so It doesnt happen again.

Thanks guys for any help
