We are having similar problems. My bump wasn’t working (Holley V5) either. It works now but it’s not perfect. I have to spend more time on the brake to get the settings dialed. Those plugs are non-resistor. Its amazing how sensitive the EFI is on grounds. David Reher of Reher-Morrison did an excellent article on grounding ignitions. He stated that on aluminum heads you need to ground both ends and that chassis grounds are not good enough. This was from the early 90’s before widespread efi.
