This si a bit of detail info that I never heard of before. In the Chev shop manual (in the fuel pump section, 6M15) it states that there is an ignition grounding circuit in the ignition switch and that the ignition switch should be in the on position while using a remote starter switch. They also state that the negative lead on the coil should be removed. The penalty for not having the switch on is to damage the grounding circuit in the switch. Has anyone ever heard of this before?
