Bummer. Well, seeing how you are new on here (I'm assuming you are new with only 3 posts) Please familiarize yourself with the fuel pump issues common to the 2011+ models. They call it a CP4 pump which Ford and Dodge and GM have in their modern diesels. It's been a source of a lot of concern by many on here as it is an expensive repair if it ever goes out. Not as simple as simply replacing the fuel pump. It does other damage as well when it goes out. With your father not having run additives (extra lubricity is the key) and having already seen injector failure, I'd imagine it puts this truck at a high risk of fuel pump failure. From what I've read on here thus far, the rectification for this is to swap out the CP4 pump for the previous generation CP3 pump before the CP4 goes out, which will be much less expensive. So please read up on that.
GM stopped using the CP4 in 2016.
