i swapped a s4 motor into my s4 n/a connected everything, when i went to go start it the motor didnt start . i figured out that my leading ignition coil was not sparking i do not know why . i tried using my friends ignition coil that worked fine and it still didnt spark and ideas on why its not working plz help my cars been out of commission for way to long.

 

well lets start with easy things...like afm is hooked up...and the main relay is tight to the frame..and then trace all wiring to the ecu.....hope tht helps

 

i dont think afm will turn the coil off.
