Spent two days chasing a no-start on a 6.7 Powerstroke that ended up being a bad ground strap

The truck had a new FICM and good batteries, but it just cranked with no fire. I finally found the main ground from the block to the frame was corroded under the insulation, which was a first for me. Has anyone else had a ground issue cause a no-start without throwing a single code?

Bad grounds can definitely cause that, seen it before.

Seen it before" @barbararamirez, but is it ever that bad?
