1999 Ford F-250 Super Duty diesel 7.3L won't start died suddenly

I started up my truck and it was warm and I headed down the road. As I was going down the road it just completely died and I heard a slight pop. I put it in neutral and I cranked it over while I'm coasting down the highway and it just cranks hard but won't start. Once I got to a stop I put it in park and cranked it over some more and it won't start. The more you know about these engines the more problems you can think of that it might be. Not because they are bad engines. The 7.3L is one of the greatest diesel engines but because of its age and high mileage and having never done anything to my engine other than glow plugs, it is getting to the point of needing some TLC.

Not knowing much about these engines I got underneath the truck right below the driver's seat and grabbed ahold of the transfer pump or the fuel pump which is on the main rail of the truck. I grabbed it while a friend turned on the key without cranking it over. I didn't feel or hear anything so I bought a fuel pump while I was in town to put it on hoping that it would fix the problem.

What I found out while researching on YouTube was that it was possibly a fuse so I checked the fuses shown in the video and it ended up being the second fuse that I checked and the truck started right up :D
