[V8] Help!! It still doesn't run!!!WTF!!

[Tony and Lillie]

    Just wanted to keep you guys updated. We swapped speed sensors, and the V8 does the same thing. Tomorrow we'll swap the other ECU into it to see if that's the problem. 
    It was suggested that the hall sender was a suspect, but it only controls the injector timing and knock function of the ignition. Since CIS runs with injectors firing all the time, I'm thinking injector timing wouldn't kill the car, just make it run a little off. Therefore, I'm leaning away from that. 
    Also, we swapped a known good distributor on the passenger side, and it did the exact same thing. 
    I checked the FPR, and there is no fuel running out of the vacuum line. 
    From my experience, it would seem most likely it is something we messed with, anyhow. 
    I'm also going to doublecheck the firing order tomorrow. 
    The most troubling thing about it though, is the way the tach bounces all over the place while cranking.

I'll keep you all informed, and feel free to throw any suggestions you may have my way,
