Hi, my name is ***** ***** 3 and six are not firing, and the coil is new, then it is either a bad wire between the computer and the coil or a bad driver in the computer, each of the three coils are fired at different times, power is supplied to the coil from the ASD relay, then the computer grounds each wire to fire 2 cylinders, and obviously it is not firing 3 and 6, do you have a test light , I can help you verify this?
