Default 05 Porsche Cayenne Turbo no spark

Hello Iím new to forums in general. Iím working on a Cayenne and Iím stumped. My knowledge I know the car has been to at least 5 shops before coming to me, the Porsche dealership didnít even want to look at it. I guess some guy did timing on the car and afterwards it wouldnít start. Engine cranks over fine, it has compression, and I know it sounds stupid but I have not verified timing yet. But the car has no spark. Iíve no signal going to any of the coil packs, they have power and ground but no signal. Iíve checked for breaks in the wires from the ecu to the coil pack connector. No breaks. Something is telling the ecu to not send the signal Iím guessing and just wanted to know if anyone else has ran into this issue or might have an idea what it could be. Any input would help. Thanks
