1996 Dodge Ram

Electrical problem
1996 Dodge Ram V12 Two Wheel Drive Automatic 122000 miles

I am a mechanic for a reputable shop and I just swapped a v10 on a 96 ram dually. But after I got through the engine spun over but wouldnt crank. So then I checked for fire at the coils and naturally no fire. Then I checked my crank and cam sensors and found that my crank sensor does not have a good ground. So then I looked to my ground connections and found no problems unless they are in the wrong place but they read engine grounds on the wiring diagram and I have them grounded to the block but still no fire. Then I jumpered a straight ground to the ground on the crank sensor wire and the truck ran but the ground jumper I ran started getting hot. So now what? Any help would be greatly appreciated. Thanks
