So my SR20 Blacktop ran beautifully a week ago, although it had a boost leak limiting me to boosting 10lbs but thats beside the point. Still ran beautifully, never had an issue.

Then I decided to "fix it", had some down time from work, yes, lets do it.

So I changed some couplers and simplified my intake piping to the turbo, ran my PCV hose to a catch can instead of the intake to get rid of some nasty blow by, and changed over some vacuum hoses that ran to my boost controller (EBC).

I tried cranking the car today, and it starts, and then falls flat on its face. Giving it gas does nothing, it starts, hits 1000rpm if I'm lucky and instantly dies.
I have fuel pressure as indicated by my FPR gauge, the fuel pump is running (can hear it humming in the background) I have spark (it obviously starts and cranks) but it just won't hold idle.

I run an Apexi PFC, could it be an issue with the ECU?

I also run a Z32 MAF, and I tried unplugging it and seeing if it would idle rough or go into limp mode, and the same thing happens, Instantly dies, so its not an air issue to my knowledge.

I checked grounds, they all clear.

I tried searching the forums and all it brings up is IACV (the car literally ran a 6 days ago without issue) ECU or MAF. I'm just mind boggled. And of course this happens a week before a big car show so time is of the essence.

Anyone else have some opinions/idea's?

Any help is greatly appreciated!
