    code 13 is fuel temp sensor 21 is coolant temp 23 is intake temp ... sounds like fuel supply pump issue can check and make sure engine module is not contaminated with coolant or oil check your low coolant sensor in surge tank unplug it and look in connection. Does the truck run good other then hard to start?
