Chris, I think he means that he blocked the exhaust gas riser that's in the center of the intake.
Did you hook up all the vacuum lines correctly? The FPR should be hooked directly to the intake. The EGR should be hooked up to a vacuum line controlled by a solenoid. Start the engine and see if you have vacuum at the EGR line. You shouldn't. Check for vacuum at the FPR line. You should have some.
Have you set your idle on the throttle body? You need to loosen the idle adjustment screw until you can slide a .010" feeler gauge in between the screw and the plate. Once you confirm you have that .010" gap, give the screw 1 1/2 turns. Once that's set, make sure your TPS voltage is at about .95 volts when the throttle is closed. The IAB needs a little help from the throttle body, but it shouldn't be able to idle without the IAB connected.
Also, do what Chris says!!
The grounding of the fuel pump test lead, by the way, is what you should do when setting or testing fuel pressure. There is no reason for the engine to be running. (That's just a side note, it doesn't necessarily apply to you. )
