Vent: Why does every 2012 Ford Focus have that same electrical gremlin?

I spent three days chasing a no-crank condition on a 2012 Focus last week. Tested the starter, battery, and alternator all fine. Finally found the issue in the body control module ground under the glove box. What should have been a 90 minute job took me 15 hours total. Has anyone else found a quicker way to diagnose that specific ground failure?

Did you check the BCM ground before touching the starter?

Could be the fuel pump relay doing its usual phantom drain trick.

Funny enough, I used to swear by checking the starter first until I had a car that drove me nuts for weeks. Your BCM ground comment actually changed my mind because that little thing can cause all kinds of weird electrical gremlins. Totally agree with what @ramirez.vera said about the fuel pump relay too, those phantom drains are a nightmare.
