P0320 - Ignition Failure Sensor Circuit Malfunction
It sounds to me like you might just have a bad ignition failure sensor. This is very common; with the engine running check for battery voltage to the ignition failure sensor on the Pink wire, less than 0.05 volts on the Black wire, and battery voltage from the ignition failure sensor on the Black/White wire. Check for battery voltage to the coils on the Black/White wire and verify the voltage is the same as the voltage on the Pink wire at the ignition failure sensor. With the engine running, scope the signal on the Yellow/Red wire from the ignition failure sensor (click over image for zoom).
