Answer 1

P1320 Ignition signal

  You replaced the ignition capacitor that is located on the fuel injector harness,and the code still appears, when you remove the capacitor you need to clean out the connection as you install the capacitor. Clear the code, If the code still appears you need to test the connection , this will determine what direction to go. If you get power and ground you replace the capacitor if no power you replace the ECM
