Cat 247B No Start.

I have a Cat 247B Serial #CAT0247BKMTL02658. I was running it yesterday and it suddenly quit with no warning and now it wont start. I checked the fuses and found what I believe to be the fuel cut off fuse to be blown. I replaced it and tried cranking and it blew again. I pawed over the wire harness to the fuel system and couldnt find any rubbed wires etc. so I replaced the fuse again and while it still wont start, the fuse stays intact. I checked the filter and there is fuel there, so I cracked the injectors and cranked for 15 seconds with the throttle wide open.



Im Lost at this point, does anyone have any input?



Thanks in advance!
