Ok, so I did get the car running. Ran rough but it at least ran.
That was yesterday. Today, cranks no start.
Pull plugs and they are about dripping with fuel.
Fuel system is as follows...
stock.
only thing it has is a B&M AFPR (screw is full OUT) with the vac line removed and plugged.
The system runs 40-42 PSI.

Plugs are Delco 4's gapped at .028"

All the IC pipes are cinched down tight. No leaks as far as I can tell.

Why would you do that?

Put the manifold reference line back on. Right now your running an effective fuel pressure almost twice spec under vacuum, about 6-8 over at 0psi and below spec ever additional psi of boost.
Then check your engine coolant temp sensor and make sure it's working.

GO to NAPA and get some NGK plugs.

BTW, you can't see boost leaks unless something is broken, ripped, or disconnected. You have to pressure test to be sure.

Trust me I would much rather have NGK's or even Denzo's.
But for me to get them I will have to order them. Which I already have.

No the delco 4's are not platnum.

I removed the line reference because it seemed to be easier to start with it removed yesterday. It actually did start yesterday with it removed.
I will hook it back on though.

I say I cannot spot any leaks because yesterday when I did have it running for quite a while (4-5 minutes), it was around 3K and the turbo was creating boost. And I did not hear any hissing from a leak.

You still need to do a leak test with compressed air. Can you see or hear a small leak that gets blow open a bit more at 15 PSI? I doubt it.
