Default Possible Fix for P0300

Recently had my engine rebuilt, the after install it started to throw the infamous P0300 code. Of course the thought was something was not put back together correctly within the engine. After checking several things...plugs, injectors, coil packs, cam sprockets, O2 sensors. I found the the fuel pump assembly had completely come apart in the tank. After replacing the fuel pump and clearing the code, the code is gone. Idles perfect and runs smooth without throwing the code.
