1 O2 Sensor Circuit

15 Ignition Output --- Electrical Problem in Circuit

41 O2 Sensor Heater --- Problem with O2 Sensor Circuit

43 Fuel Supply --- Problem with O2 Sensor Circuit or Fuel Supply Circuit

So i would check your o2 sensor once again...for 3/4 of your problems that seems to be it...also check the Main Fuel Relay as well
