Ok, you say that you have power with the ignition on. How about during cranking. You sure the power stays on? Secondly, when testing the coil plug for signal with for example a bulb or a test lamp, it should blink when cranking. Thirdly, When resting the, let's say plug #1, on the head when cheking for spark disconnect completely the HT-cable from plug #4.

edit:
Are you also sure that the air-gap between the CPS and the flywheel is corrent being just a couple of millimeters. There are many different length CPSs in different age EDIS-4 equipped engines.
