Customer Question

I have a 2012 international 4300 box truck maxxforce. I would say there's an issue with the lift pump and possibly with the sensor injection control pressure. The 3 active codes are 2797fmi4 2003fmi31 3359fmi31. What do you think is the issue? I don't know what the codes are for. Can u translate them give me your opinion. Thx. Leo
