Your on the right track, the fuel injection pump/ fuse is where I would start. Locate the fuse for the pump (easiest to check first, ok easiest would be to make sure diesel is in tank I guess ), and make sure fuse is good. Next I would check to make sure pump was getting power, if so check to see if fuel can get to pump (not plugged ), then test the pump with the outlet off and see if you get fuel, if not and if all those check out bad pump.
If I forgot something, I'm sure more people will respond. Good luck.
