Well folks I come here a bit dismayed.

A week ago I bought a 2018 Ecodiesel with 40k miles on it. On my drive home from the dealership a check engine light came on. I promptly brought the vehicle back. They informed me it was an issue with the Fuel Sending Unit. It sat for a week until parts could come in. They then replaced the fuel sending unit today. Great, right? Well now that the Fuel Sending Unit is replaced the PCM won't interact with it and they have to replace the PCM.

Has anyone experienced anything like this? What was the issue?

All recalls have been accomplished. Please do not mention the lemon law or returning a vehicle, I don't have that recourse available to me. Just trying to figure out what is going on here.

Any guidance is appreciated.

With all of the electrical connections on these trucks, just start unplugging appling a dielectric grease and reconnecting.
