Hello everybody. I am working on a 04 911 c2c.  after a full engine rebuild the engine started but only runs  on cylinder 1,2 and 3 (bank 1).  When I disconnect the bank 1 cam sensor bank 2 runs fine but bank one ignition is turned of. After reading any codes I only have the temperature sensor on , I believe that's because I have not brought the engine to operation temp to open the thermostat. when I disconnect the injectors wires on bank 2 it shows up on the diagnostics tool as a code. if I disconnect the ignition coils on bank 2 it does not show up on the diagnostic tool. I also disconnected the maf sensor if it makes any difference but noting changed and it also doesn't show up on the diagnostic tool. I was hoping somebody can help me with this unique situation and if there is anything in particular that would disconnect the ignition of bank 1 or 2. thank you very much for your help in advance.
