Default Fuel to Lines, Not Starting?

On my 2005 STi, I cant seem to get it started now. Mod list below, the fuel pump primes, has spark(I've checked), is getting fuel to the lines by the intake manifold, has an appropriate base map, and is just cranking.

I hear the fuel pump priming when I turn the key, there is fuel flowing through the lines, but it just keeps cranking. Checked for power from the harness for the injectors, all getting power. There is no fuel coming out of the cylinder heads when I pulled the plugs and primed, which is weird.

There must not be any fuel getting to the heads, right? No clue why. Any ideas or anyone had any similar problems? I timed it perfectly lining up with all timing marks, the timing cover, etc. I guess I'll have to pull off the Intake Manifold and check each injectors to see if its spraying. No other ideas. Any ideas or help is appreciated.

Btw, I checked the harness connectors and they ARE sending electricity.

Motor needs air spark and fuel to start.

If spark and fuel are good and no cels present try checkibg for air leaks.

Injectors arent leaking?

Really make sure those 3 lines that deal with fuel are in there correct spots.

Ones fumes. Fuel out and fuel return.

Ive done this b4. Turned over all day but didnt start

Yeah. I checked the air, everything's connected. Running on a speed density set up so no maf or intake. Also, checked those lines and they're in the right spots. No cels, spark but like I said no fuel out of the heads with no plugs. Gonna pull off everything an check for blockages in the fuel rails

THIS!

Additionally, we have seen it when cam and crank sensors are out of sync (unhooked, time off)

We have also seen it when ONE little tooth is broken off the crank sprocket.

AND we have also seen it when the grounds to the block are not tight (for real). Add to that if you're using the composite TGV deletes you have to move the ground from the top of the intake manifold to one of the long TGV bolts as you're now electrically isolated from the block.

THIS! Gotta move the ground from the intake manifold to the tgv bolt then. I'll do that tomorrow morning. I thoroughly checked the crank sprocket before reinstalling it. Both sensors are installed but may be out of sync even though the timing markings all lined up 110%

I had the same problem and I mixed up the fuel lines going to the rail in the drivers side.
