Just to confirm you replaced the coil assembly (including the control module) or just the coils for each pair of cylinders?
Here is a guide that helps with this issue but we already figured out the problem system in the ignition:

I attached the info below on the assembly. Take a look at how it operates which is why I am thinking the module is the issue because this picks up the crank signal and delivers that info to the ECM. So if you take a look at the diagram it shows this better. We need to confirm this by testing voltage coming from the module to the ECM and back. In my opinion it is the module or the ECM and I am thinking if the module was not replaced with the coils that this is the issue. Let us know what questions you have. Thanks
