Yup, you need to prime the pump. I rebuilt my engine a couple of years ago
including a new oil pump and had exactly this problem even though I was
told repeatedly by tech support at TRF that it wasn't necessary.
To do prime it, I removed the distributor and to get to the top of the oil
pump. I then notched one end of a plastic hose, the type used to connect
up a sink to the water supply so that it fit over the top of the pump and
then used a drill to drive it. It took a few minutes with the drill to get
it to start pumping oil but it finally did. If this hadn't worked, I was
going to take the pan off and pack the oil pump with grease.
Good luck!
