Are you doing the test with the engine not running?
If so theres your crank sensor fault, engine aint running.

As for the knock sensor, definently got the right plug on it? (the red one)?

most xe's and let's will bring up code 31 (crank sensors) if its not running as it cant see a signal from the sensor (as the trigger wheel is not moving)

knock sensor if its an earlier let you will have two matching plugs by the kock sensor and idle speed control valve. one plug is red one is black. the black is for the ISCV the red plug is for the knock sensor, make sure these are plugged in the correct places.

Does the xe light flash up when driving?
Or are you just flashing the codes out to see what it had stored?

Alan, Unplug the ECU for a few hours and plug it back in (to reset it). Then start the car and check for code's whilst its running.
