When you installed the new oil pump, did you rotate the pump body it insure driveshaft engagement? Here is a picture of the distributor drive shaft with the pump. You can see how it has to go together. If it isn't, you need to remove the pump and reinstall it. If you have a new pump, you should have pressure.
Let me know if this helps or if you have other questions.
