Code 164-2 is injection actuation pressure erratic.
Code 164-11 is an injection actuation pressure system fault.
Code 42-11 is a fault with the out dc current to the Heui pump.
With all of these codes. You most likely have a faulty Heui pump. It could be the two wire connector to the pump so I would check the wiring first.Please reply back if you need more help or have more questions. I am happy to assist.
