    Default Terminator/HP starts, but immediately stops.

    So I'm having an issue keeping my 393W running. The engine will fire up in the 2-4 seconds range, but only runs for a second or two then dies. If you give it some gas pedal it will run longer, but as soon as the gas pedal is lifted the engine dies. Throughout my search about the problem everything seemed to come back to either fuel pressure, bad base calibration, or IAC issues. So at this point, I've checked the fuel pressure, which is right at 43 psi. While the IAC and blades, I'm not sure how to adjust them without the engine idling. Is there away to adjust them with the engine not running? The Base Fuel Table I used the 409 cubic inch and under base, would this be the correct one to use? I’m pretty new to laptop software, the last time I set the tune with the Wizard on 3.5” not the laptop. Ultimately, I believe something is wrong or was overlooked. The firmware was upgraded on both the ECU and 3.5" to the V4 base 110. Ignition Parameters found in the dual sync instructions. The timing synced to the best of my knowledge. The engine is:
    Ford 393W
    Medium Size Cam
    200cc WP Heads
    Holley Dual Sync DIS
    MSD 6
    MSD HVC2 Coil

    Any help or direction on where I should look or go next is greatly appreciated.
