Brad,

If that doesn't do it, I would have Corey recheck his calibration. Basically, you have too much air flow with not enough fuel because injectors aren't coming on line because ECM won't let them because it doesn't see enough vacuum to keep throttle plates open.

Mike,

The solenoid only operates a check valve. I don't have mine. Don't have pump either. As long as ECM sees a voltage of > .7v(I think), it's happy. So secondaries will come on once you get to TPS% value programmed to turn injectors on.
