0 psi, need help

[gsxspeed98]

Ok I was driving the other day and I was boosted up to about 5 psi, I shifted and the bov made the normal psssht sound. I then came to a stop at a light. Once the light turned green, I started to go only now I get no boost at all. There is no loud leaking sound, the bov makes no sound, I tried to do a leak test but it won't pressurize at all, the compressor wheel spins freely with the car on and off. I have no idea what the problem is. Things you may need to know: I have a tial ex. gate, a gm maf and maft, and the car still idles fine. I checked my intercooler pipe connections and all seem intact. Please help.

If the intake tract wont pressurise at all something is venting the air.

First thing I would check is your BOV.

I dont know if this will help, or if you already checked this but My wastegate arm actuator came off one time and it was too dark for me to see that it was a simple problem like that . I couldnt build past 0 either. The next day I put it back on and everything was fine

Got it. I had blown an intercooler pipe coupling that I couldn't see until I started taking things apart. Thanks for the help though. I appreciate it.
