Cold morning stall (Narrowed down...maybe?)

I posted a thread last year about my car stalling on cold mornings. I replaced a few things trying to fix it and came up with no results. I replaced the fuel filter, vanos seals, cleaned the ICV and I read a few maintainence records that show the previous owner had both cam position sensors and alternator replaced. I never did replace the secondary air hose which I was told to do. I am gonna do that next but I was wondering if anyone else knew what else that it could be since I narrowed it down a bit. I was thinking it could be more fuel related? like the pump but it makes a noise indicating that it is functional when the key is in the on position.

I'm just really annoyed right now since I also have to replace my power steering pump and rack... a second time. Well rack is a first.

I appreciate dearly any input on this situation that could lead me in the right direction...I've been searching all day

SAP vacuum lines and DISA are very likely culprits.

Thank you! Very nice thread you made

+1 on sap. Check both the hose from the pump (for a hole and/or for squishiness) and check that the vac line is intact too.

Also, look in the valve to see if it's clogged from decomposed hose plugging it up. I had this issue...and it caused my car to stall on cold start.
