Ok here is the short rundown. I replaced my in-tank fuel pump with another stock unit. I am boosted with the Hahn Stage 2 kit. After replacement, the car sometimes runs right, but most of the time will not. It's basically like something is completely limiting the fuel pressure to absurdly low levels, around 10-15psi total. But as I said, sometimes I fire up the car and it runs like a champ. I have a CEL with 3 codes. 2 are identical as "Emission Control Pressure Sensor Low" (I think that was exactly right) and the other for a "Random and Multiple Misfire" which makes sense since the car is getting hardly any fuel. So I have never seen the emissions code before. If anyone has a clue as to what this is could you please let me know. I am completely out of ideas on this one. Thanks guys.

If it helps I now know that the code is a P0452. I know its emissions related, but have no idea how to fix it.

you would probably get more help in the boost forum.
are you just running the turbo w/ a stock ECU?
