First thing I did was check the EGR. Its brand new. I just looked at Live Data on my scanner and all the sensors return reasonable values. I think the codes are "permanent" codes that are cleared and will automatically delete themselves after its driven. Our 2015 gas Cruze saves misfire codes like that too. I suspect the car flippers replaced lots of stuff shotgun style and all those sensors are actually new. Without knowing a clear history I might drain the fuel and focus on the glow plugs next. It sounds like its trying to start when it cranks so I would believe its just disconnected glow plugs.
