Swap the coil to another position, see if problem follows the coil, if it does, suspect the coil.

I see you replaced the suspect coil. Remove the coil, use a testlite between the ignition module primary terminals, those prongs, have helper crank, if the lite doesn't pulse, I suspect the ignition module. You have spark at the other plugs, correct?
