On systems such as MSD (or in this case EFI) which no longer use a coil ballast, the "run" known as "IGN1" goes dead in start. This was "used to be" traditionally powered during cranking with the "bypass" (IGN2) circuit. HOWEVER there is / can be a slight disconnect or gap as the key is moved from start to run. Evidently this becomes a problem with some EFI systems
