looks like you got the "559" code of engine destructing doom, did you change the tappets and plungers when you replaced the pump? That code usually means one of those things are/ or have failed!!! You could also have a big fuel leak somewhere or a bad pressure check valve or something if the pump, tappets, plungers, or head is all new. Definitely do not drive it anymore until you know for sure the pump hasn't gernaded!!
