Bad fuel rail wiring harness?

[Brian41]

Dealership is saying this is what they believe is the cause of my 2015 sports intermittent loss of power. They have had the vehicle for one month now. They thought it was the turbo after duplicating the issue, but that was a guess, because there has never been an engine light or code.

They have had their technician driving it to and from the dealership with diagnostics hooked up trying to get it to lose power again. I don't think it ever did lose power again, but they are saying that with the diagnostics and talking to Ford, this is what they think is the problem.

I know what fuel injectors are but had never heard of a fuel rail? They are saying the issue is with the fuel rail's wiring harness. Does this make sense? I'm hoping their right and not taking a stab in the dark here, but this sounds technical enough that something had to lead them in this direction.

Are you still under warranty Brian? If you are a "stab in the dark" won't cost you anything except additional time without your Explorer.

Fuel rail runs across the engine and the injectors connect to it feeding them with fuel.
