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
