05 Porsche Cayenne Turbo no spark
Hello I’m new to forums in general. I’m working on a Cayenne and I’m stumped. My knowledge I know the car has been to at least 5 shops before coming to me, the Porsche dealership didn’t even want to look at it. I guess some guy did timing on the car and afterwards it wouldn’t 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. I’ve no signal going to any of the coil packs, they have power and ground but no signal. I’ve 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 I’m 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
