#30 is for Wastegate Solenoid, Fuel Heater and Injector Driver Module Relay Coil. Without power to the IDM it is not going to run. The reason the fuse blows is probably a shorted out fuel heater. Try unplugging the fuel heater and see if the fuse still blows. The 94-97 trucks have the same issue but on them it is fuse #22.
Side note: On the newer 6.0 engines the #30 is the headlights. It would help if when asking questions you would fill in your signature line with just what year of truck you have.
