Yes, I used an old style pulley. I was correct in saying that it didn't seem to be spitting any fuel out from the delivery valves. With the lines completely off, they barely dripped any fuel whatsoever. I put the old pump back on, didn't try timing it at all, and even with all four injector lines cracked, it almost started. I closed two and it started, closed all four and it purred great. At this point I checked timing and it was damn near spot on, so I called it good.

I have been trying to contact the seller of the pump, 8v-of-fury!, to no avail. I see that he hasn't been online in a while. I need my money back, as I bought this as a ready to go resealed unit. I ended up fixing the leaks on the old pump myself and it hasn't started leaking yet.

Any chance the throttle arm is  off a spline or two?

Tried that. It's not pumping very much fuel, it is barely a drip, not building enough pressure to open the delivery valves.

You should take the top off the pump and verify that the throttle lever "nub" is actually seated in the piston collar.

Yes, the problem was that it's not spraying fuel, I'm thinking it's not building enough pressure to pop the delivery valves, because if I loosen them up it will pump, but as soon as I close them, only a very very small amount comes out of the valves.

If the throttle nub is seated properly in the collar, I would try using a feed pump, removing the entire external throttle arm assembly including the springs and then turn the throttle shaft all the way counterclockwise.
