Have 2004 F350 with, 2006 notor. Motor has 110K, Has always been a poor starter but recently got worse. It was puking black smoke until warmup. I had FICM from previous motor. Both the 4 pin ones. I installed previous one and trucked started but ran worse. When it warmed up it ran better. It was idling and just quit.. Towed it home and reinstalled original FICM. It will not start and has no voltages on FICM. Appears to have an open fuselink as right third of fuse panel has no voltages. Five fuselinks off battery are good. Have 12v on FICM fuse in panel. also have 12v on 20A fuse in FICM control cct. No voltage on the 10A. What am I missing?
