Default x24 converted lt1 dies right after startup

Just finished up efi connection conversion on my 96 camaro with lt1. car dies after few seconds of ideling. If i try to rev it, it dies even faster.
I checked fuel pressure, its around 45 psi and stays there even after car dies. When i say dies - it stumbles itself, kinda like it runs out of fuel. Checked every coil for spark with spare spark plug and cable. Good there.
checked voltage on the pink wire on every coil its above 13 when started and stays there until car is dead again.
I have VATS set to "none" in the tune.
Tune is pretty good at idle. Its stated happening half way through tuning process. I had it ideling and light driving tuned in nice. car was shut off and restarted with this problem. Going to previous tune didnt make a problem go away, so thats why i am thinking its something mechanical. any help will be appreciated. I am out of ideas

Default Did you solve it?

I know this is an old thread.

How did you solve it? (Did you solve it?)

Sounds like MAF signal to me, but I don't know for sure.
