    Case 580sm wont start

    We have a Case 580 super m series 2, it had died the other day while backing up. Sounds like it is not getting fuel, just turns over but wont fire. Tried replacing fuel pump, relays/fuses and fuel solenoid. Still no luck it seems to be electrical but not sure, any input would be great. Thanks.

    Does anyone know of a "Master List" of some sort that lists all of the options variant codes? I have a parts manual that has variant codes listed on some of the pages but they aren't included in the variant code list at the beginning of the book. Thanks!
