I upgraded my '91 based 302 with 24 lb injectors and new BBK 70mm throttle body and 24lb MAF. I can't get it to start. Did the initial setup-disconnected the AF valve. Fires once. If I turn off and retry, it fires once. That's it. I called BBK and was underwhelmed. Maybe turn in the idle stop screw a whole lot until it (hopefully) fires? Waiting for the battery to recharge. One other thing- I'm using a '94 style MAF, #8009. This shouldn't make any difference, should it?
