2001 F250 GEM/4WD Issues
I just bought a 2001 250 and 4WD doesn't work. I checked all the shift relays and shift motor and they are working. After scanning codes I have no communication with the GEM. I have power to fuse 15 GEM constant power, but no power to fuse 20 GEM ignition power. I tried jumping 12v to fuse 20 while the key was in the on position and it tried to crank. I pulled power immediately. From the Alldata schematics and plug diagrams I don't see where any wires are going to the starter or starter related accessories from the GEM. Dont know why it tried to start. I will post all diagrams I have used soon.
Anyone have any clues, I am assuming the GEM but I want to rule out all other options before shelling out 450. I guess it could be something wrong inside the fuse box since there is no ignition power to the fuse. Any help would be appreciated. I have power lock issues too, I am contributing this to the GEM as well.
