well i have a 2003 silverado and droped a 2008 6.0..but im having problems turn it on..the knock sensors are on and i bought the harness from lingenfelter to simulate the 24 relactor wheel to a 58..but it doest whant to turn on..one of the things that i notice yesturday was that theres no spark on the coils..has anyone done this conversion that can help me out..

 

check the ground wires on the rear, there should be 2 solid black ones, and one braded flat ground. On the Drivers side, there's another, right next to the battery box

 

thats done already,all grounds are good...
