I have a feeling that control unit may do the same thing. If not right away, perhaps later. Hopefully not. I just don't think the ignition signals are compatible. I also realized that another function of that unit must be the original Rev Limiter. This may explain why the fuel pumps shut down sometimes, if whatever IC in that unit is going haywire it could be shutting down thinking it's at redline. I need to spend more time on the wiring diagram and see what all that unit does.

One thing I'd like to know is if the fuel pumps still run all the time with the key on if you unplug that control unit. Also, if the tach still works with the unit unplugged, although that could be difficult to test if the fuel pumps don't run.

Try that and let me know so I can ponder some more. Good luck
