Did you prime the pump before installing it? I wouldn't run the engine until you take a look at the pump. It may have been the culprit that caused the rod failure. Set that pump in a clean container of engine oil and spin the drive gear by hand and see if any oil is being discharged.
It's a good idea to pressure lube the engine during the initial start with a pressure vessel.
You can use an electric fuel pump to pump oil into the oil gallery. Hal
