Dave, that's a good point, but isn't the coil in the cap on that year?
I don't think so. My multiport Edelbrock is based on a '93-'95 GM ECM (bank fired). The coil is separate from the dizzy on mine. The dizzy contains a servo for timing advance. The servo is controlled by the ECM, so assuming his ECM is of the same vintage, the dizzy would have to be the same.
BTY: If it does run with the coil isolated, I would not shut it right back off. There should be a separate physical ground wire that goes to the engine, but it could still want to send a small amount of noise back to the ECM. Long term that could be hard on the ECM.
