1. Did you bleed the air out by turning over the engine without starting for 15 sec, wait a bit, then 15 sec more? Even with that it may take a bit of time for the air to work out. Make double sure you charge your batteries first. You don't want to fry your FICM.
2. Which oil pressure is low, engine oil or high pressure oil? You'll need torque pro or some other device to know about high pressure oil. Engine oil should have a gauge on the dash.
3. Any time you replace injectors there's the chance a standpipe/dummy plug o ring has failed, or the nipple seals failed. I've had that happen twice when working on injectors the past few years. I did an air test each time to detect the leak.
Good Luck.

Do you mean that you are getting ZERO oil to the oil filter when you crank?
If you are getting oil flow, how long does it take in cranking to fill the oil filter housing?

If the gauge isn't showing pressure, could just be the sensor. I'd try that first before digging into the engine.

Might have messed up the oil filter standpipe(?) pulling the turbo out. I've done that. If it was me, because it's me, I'd go back to the oil cooler cover. It started last time, and that's all he's messed with.

Hmmm... he did say he changed out #1 injector so had to take the oil rail, standpipe and dummy plug out, right? I damaged a standpipe o ring once going back in (at least I'm blaming it on myself) and it lasted 50 miles and died.

Three things I can think of.
