secondary fuel injectors not working

i just did the s5 intake on an s4 swap and i'm checking everything because my car isnt starting. and when it does it sounds like its either running on one rotor or just living off the primary injectors.

when i took the secondary fuel rail off, i kept the injectors in and tryed to start it and nothing sprayed out.

what would make that happen?

i have fuel pressure in the rail. and the vaccum hose connected to the nipple right below it.

Secondarys only work over 3800 rpm AND a LOAD on the engine. Never below 3800 rpm.

make sure your pressure sensor is hooked up and no vacuum leaks
