starts but wont stay running after HG job

[macksterminator]

Hey everyone! I am thoroughly stumped! hopefully someone out there can help!

I received this 99 forester with a blow HG, it sat for 2-3 months before being worked on.

No major hiccups in disassembly/reassembly.

Now that its all back together it starts right up the first time but will only run for a few seconds then shuts off ( while pumping out white smoke). You can keep it running with the pedal but the second you stop giving it gas it dies immediately.

What I do know is;

 

No codes thrown on Boshc reader

Spark is good 

Compression good

All  vac lines connected/airbox fully assembled

All vac lines replaced besides the large diameter Y shape hose between PCV/airbox  and valve cover breathers 

Fuel rails, pressure regulator and injectors cleaned by hand 

New fuel pump 

Fuel filter not replaced because fuel flows steadily out

Fuel pressure solenoid switched with one that works(wrong name? ( green cylinder with prongs under drivers side dash by left knee)

triple check the hose from the IACV under the intake tubing.

I have no idea what you are talking about here.  Are you talking about the fuel pump relay?  IDK  not the issue

 

 

 I would suggest check the MAF Connector?
