car

I own a 1997 dodge stratus 2.4 liter. my problem is the number one coil is not firing. i changed the coil pack ,wires and spark plugs, and checked all fuses. the car starts but runs rough due to the number 1 coil not firing. checked wires that plug into coil pack for power middle wire has power black wire i assumed was ground wire has no spark but other wire to coil pack blue green wire has no spark out of the three wires
