Unless I missed it you never said what you are using for a trigger input. flying magnet. distributor, multi tooth crank wheel. Does the bigstuff unit have an diagnostic LED on the box, and if so what happens when you crank it? Also are you using a cam sync for sequential EFI? After reading back through the posts I'm going to say you're running an MSD ignition box, hooked to the big stuff controller for the EFI side of things is this correct? And if so and you have no spark...look at the MSD part only for now, if the MSD has no spark then you probably aren't producing a tach signal for the big stuff system to work off of.
