Help

I have a 04 xc70. Cylinder 4 has a misfire. I changed the plugs they're gapped correctly. I changed the coils and it still misfired. I did a continuity test and there's no power coming from that single harness. I chased the wires and there's no breaks. What should I do next? Has anyone else dealt with this before?

If you have made sure there is continuity between the coil(s) and the ecu and the coil(s) and grounds as shown on the diagram - the only thing left might be a problem in the ECU itself
