Forgot to connect the sensor to the harness, or broke it doing the intake? It was OK before the swap right?

Probably a pic here somewhere - but it's the vertical cylinderical black sensor behind the intake, on the drivers side.

Thats your problem. My son just finished taking the intake back off cause of the same problem. Did an LS6 intake swap yesterday, started it up and no pressure. Sure makes your butt pucker.
