Ok I have a 97 f150 4.6 vin 6 I purchased a remanufactured 4 6 vin w , engine installed with very little issues, only problem I'm having now is I get no spark from the 2 coil packs , any suggestions or help would be greatly appreciated

 

Welcome to the site..
Power to the coils primary side?
Do you happen to remember if you plugged the knock sensor connector in?
CKP, CMP, too, but doubt that would be missed.
