No oil pressure after turbo install

No oil pressure after turbo install
I completed the turbo install this week and was excited to start it! But...
No oil pressure :(
I pulled the injector relay and tried to turn it over for 60 seconds, no pressure. So I started it, still no pressure.
I checked the oil pressure sender connector - it was fine.
I disconnected the oil feed line to check for oil - dry.
I disconnected the oil filter to check for oil - dry.
So... is it either a "priming" problem or a problem with the oil pump? Am I looking at removing the oil pan? Is there a recommended way for priming, or just leave the filter loose to let any air out?

what do you mean by check the oil pump? prime it? pull the pan?
i drilled where BEGI recommended, as precisely as possible. the bit broke through, but i certainly didn't drill once it did, and i ran the tap through as recommended also (bury it with 2 threads left). is that especially close to the pickup?
FWIW, i used probably 3 quarts of mineral spirits to flush it out and left the drain plug out overnight.

did a little more reading, and starting to understand that it's fairly easy to make a pickup tube mistake. the begi instructions did not give me the impression the tube was so close behind there, so i am now concerned. yet i should hopefully be able to inspect by removing the oil drain.
anyway, please let me know a recommended way to check the oil pump.

This is advice i got from a greybeard at one point. Ive never tried it so use it at your own risk.
Do you have a vacuum pump of some sort? If not, go buy one. Any cheap hand pump should do, like a MityVac. Get a cheap oil filter, a 1/8" brass hose barb, some JB weld, some clear rigid tube and a drill. Drill a hole in the filter just large enough to stick the brass barb into and then JB weld it in place and let it dry overnight. Don't introduce metal shavings into the engine via the filter, don't say I didn't warn you. After the epoxy dries overnight, put the filter on the engine and start cranking away with the vac pump via the clear tube. This will probably take a while. With any luck, you will see oil in the tube and will thusly have primed your oil pump.
If you punched a hole in your pickup tube, no amount of vacuum is going to prime the system.
Good luck, and I hope your bearings are OK.

the other way i have heard was leaving the filter loose and cranking; is that really valid?
i did not run the engine long. i heard the lifters and knew better. did not time it, but it was not long. i also hope they are OK...

I will take that advice.
I left the filter very loose and let the engine do its last few cranks before my battery died. I took the filter off and found that it was nearly filled with oil. This differs from the empty/dry one I had before.
This seems to be good news. With a charged battery, I will probably do that some more, then tighten the filter and see whether I can get good pressure.
Sound reasonable?
I am wondering if this is necessary because I had no oil in the car for over a week due to prolonged install. That would have given time for everything in there to drain out. I guess I am hoping for that.

The oil pump has a allen key screw on top of it near alternator....take it out and crank engine over.
If you can stuff a tube in there to keep the mess down all the better. If you get no oil gushing out there then you can be certain you have an issue in the oil pump/pickup tube
I've also poured oil into the pump that way ahead of time to help with the initial priming...it's a pain but gives you instant oil pressure.

i am considering dropping the subframe to get the oil pan off. i watched "mike Miata king"'s video and see that it is something like 18 bolts and maybe the power steering lines. with power steering and a/c, i am less comfortable pulling the engine, or at least think dropping the subframe is comparable. the impact should make quick work of those bolts, or most of them (that i can get to), and re-install should not be too bad, right? re-aligning things may be painful.
i might be off base with that.
I've got an impact, engine support, half a dozen jack stands, and two jacks. hoping that i can get the oil pan off without having to disconnect the P/S lines and steering shaft, maybe not.
regardless, a lot of work for an inexpensive part. too bad i wasn't smarter about this.

its more work than needed to leave the engine in place to remove the oil pan.
lowering the subframe is more work than pulling the motor.
fwiw, leave the PS hoses connected, just unbolt the bracket from the engine.

The problem comes when you go to reinstall the oil baffle, pick up, and pan. Take an engine out and pull the pan and it will sit there and drip oil on the ground for weeks.
Pan install requires the following:
1. RTV around the entire border
2. install rubber half seals on either end
3. place baffle in place
4. bolt up pickup tube with gasket to oil pump, and tighten to baffle
5. RTV both sides of baffle
6. RTV tops of rubber seals
7. place pan and tighten up
Now think about doing this while upside down. You need to keep all surfaces clean. I prefer to use alcohol to clean them, binds to the RTV better. On top of that, you need to hold the two seals, baffle, and pick up in place as you bolt the pan on.
Now, imagine throwing it on a stand, flipping it upside down, and doing the same. Much MUCH easier.
