Why am I still getting "death code" after changing injector and lift pump? on 2002 Dodge Ram 2500

I have changed my injector pump for a rebuilt one and installed a raptor lift pump also, at the same time. Truck no longer has symptoms it had before and is more responsive etc. but still getting code 0216.
