Yeah, after all that I would definitely make sure the pickup is there. Then t I would pull off the pump and make sure the bypass isn't stuck open. I like to pour a bit of oil into the pump before I put on the pickup, cooler, and pan. Seems to help.

Was your oil pump packed with vaseline before fitting? A totally dry oil pump will not be able to generate any suction to pick up the oil.

You should just pull the pan. I have seen this before and it turned out to be a hair line crack in the pick up tube at the top. The other is the backing of the oil pump itself, the screws have been known to back out from time to time. It can be lock tightened back in but you have to completely clean it and do put some oil in it. before you put it back on it really does help.

Oh right, yeah, the bypass is under that plug. Ummm I guess the pickup would be the first thing to check. After that you may need to get a new pump or figure out how to get it apart.

The pump comes with a little bit of grease/packing fluid in it and will prime ok if you just bolt it on. I took one apart and cleaned everything once and that car wouldn't build pressure until I pulled the plug. After that I always made sure there was oil in the pump and filter.

Not true at all. Vaseline helps but is by no means "a requirement to generate oil pressure".

Pull the oil pan, it is the easiest option for you and will tell you a lot about what is happening. Is the pickup tube installed? Is the o-ring on the pick up tube there?
No cracks in the pickup tube?

Take the tube off and hold your thumb up to the oil intake port, have someone crank the car. Feel anything?

If the pump is dry dry dry you can try to pour a little oil down through the oil pressure screw location in hopes of wetting the gears. Just a thought. If your pump needs this to prime it's probably no good anyways though...

Let us know what you find.

Who built this BTW? Oil clearances checked?

I did talk to shop owner this morning and he told me subarus are a p.i.t.a. and to just start it up and said the prelube will protect the bearings for a little bit. He said to start it for 30 seconds, then if no pressure still to call him. Doesnt sound good to me, im really uncomfortable just starting it theres too much $$ in parts in there to risk imo

Be sure to check the o-ring on the pick up as well.

I would NEVER tell a customer to just start it when they know they aren't getting pressure at this point

cracked pickup tubes are somewhat common.

This is probably a stupid question but do you have all your harness connectors plugged in? I know some places tell you to leave one or the other unplugged so the car will not start and you can build pressure but if you have the wrong one unhooked, your oil pressure light will stay on because it is not connected... If you have an electronic oil pressure gauge, its likely lost all pressure by the time it does the sweep/check upon powering up. If this is the case, plug everything back in and unplug your injectors and coil packs and try again. Should take 3-4 8 second cranks to build pressure.

Are you certain it is cranking fast enough? I had a similar scare on my build here's how it went..

Primed the engine without spark plugs in and it cranked fast enough to build 80 psi.
Went to eat dinner, came back to start the car.
Put plugs in, decided to prime again for safety measure...
Couldn't build any pressure. I started worrying, took out plugs to see if it really was the cranking difference. Sure as hell, built all of 80 psi.

I understand you had plugs out and a jumper box on it, but BE SURE it is cranking fast enough... could be a bad connection at your starter or a weak ground providing a slower crank time.

Other way around. Disconnect the sender and the light will never come on.

I bet you used a 12 point socket to round the plug over. Try a six point socket. The bypass is probably stuck in the pump or the pickup has a crack or leak. You might try to put enough oil in the pan to get to the bottom of the block, I'm guessing two more qts, you need to change the oil after startup any way, and if it picks up oil you will know it's sucking air at the pickup either from a crack or where it's bolted on. I would drain some back ouy when you figgure out whats what. I hope you didn't use a floor jack or any jack on the bottom of the pan there is not much clearance between the pan and the pickup. If the pan is bent any, you need to remove it and take the pickup off and look at it real close.

I bet you've never actually looked at an oil pump. It's a hex plug, so you need an allen socket to remove it.

Yeah I forgot, it's been a couple of years since I did some oil pumps. If you think I've never done a suby search my id in built motors. I guess he just didn't hold the allen socket firmly enough to get it loose. Probably like the screws on the back of the pump. Check out available oil pumps thread, it's long about post 153 in 2007.

I wouldn't do that either. Internals will heat up fast if oil pressure doesn't come up!! Plus of it starts making any interesting noises you'll not hear them!

You can try starting it
You can pull oil pan and check o ring on oil pickup and check for cracks

Or you can pull oil pump off and check Relief valve.

I'd start with oil pan. It's easiest

It's not that bad to time a Subaru. Biggest issue is having a good set of tools that aren't rounded off for cam gears.
