Message	to the plenum ground point; just on the other side of where you have it grounded now. I recently installed a new EFI harness, fuel rail & injectors and left the two ground wires together; near cylinder six and the number two coil wouldn't fire. I re-grounded them at a 45-90% angle and all coils fire now! I hope this helps with your issue. Samuel (Dallas) 91 TT +5
