Default Help!! OBK wont start after swap

Need some help here. Recently bought an 05 Outback, 2.5 Auto 142K, with a blown motor. Swapped in a new engine assembly and now it wont start. The outback was in perfect running condition prior to the motor blowing.

Heres what I know:
-New engine already had an untouched engine harness attached
-Wont start in either park or neutral
-There is spark
-Crank sensor and cam sensor tested good
-Fuel pump is priming and fuel is getting to the fuel rails
-Engine will run when spraying starter fluid in intake but dies when you stop
-With Key in "run" postion (Last click), there is a buzzing noise coming from the neutral safety switch when put in reverse and drive (Not sure if this is normal or not)
-New battery
-Did the screwdriver trick to "hear" if the injectors were operating while cranking, heard nothing after multiple tries
-Pulled plugs and no fuel residue on them after trying to start
-Feed and return Fuel lines attched to engine correctly
-"New" engine is from a manual trans car

Any help would be greatly appreciated, Ive searched and searched and cant find any answers. Any questions just ask!! Thanks!!

You've narrowed it down to the injectors not working. Focus on that. Since all of them aren't working, it could be a control issue. Engine-wise, I don't think there's a difference between manual/auto, so any electronics wouldn't know the difference. Check the main wiring harness connections for continuity to the injectors, make sure they're plugged in correctly. How are the grounds looking? Can you swap ECUs? Have you checked all the fuses?

Yeah I think the next thing is to see if the injectors are getting a signal, if they are then its an injector issue, if not then its before the injector.

We checked all the grounds at the ecu for continuity and they checked out good.

The harness that was on the "new" engine has never been touched from the factory.

Dont believe we have access to another ecu, and yes we checked fuses.

thanks for the reply!!
