I was having low oil pressure at idle. Found the high volume oil pump kit that came with the car. Has 2 other springs in it. Took out the yellow one and put in the blue stronger one. Found pressure was 100#'s cold and no difference at hot idle. (Should have read up on it first) Tonight I wanted to switch spring back to yellow. Undo the cap, take out blue and put yellow in with the plunger on the end of the spring. Now I got NO oil pressure. 
Ran for about 15 seconds and nothing, lifters were starting to make noise.
I noticed that the steel plunger on the end of the spring has 2 slotted holes in it. Do these have to line up with something or go in a certin way? What could I have F'ed up, did the pump loose prime? Only about 1/2 OZ of oil came out when I tool the plunger out. It there something that the plunger pushes against that could have fallen out? There is nothing in the drain pan.
