Customer Question

93 corvette. driving along, went to running on 6 cyls for about 4 minutes, dropped to 4, for a couple minutes, then less and would barely run and stopped. no start. Seems to have no spark with a sprkplug out and grounded and someone turning it over. Got a opti spark from autozone, hooked it up to wiring, turned on key and spun it with a drill motor. One little spark.

does the opti spark I used for my trial need to be grounded? It wasn't in a you tube video I watched.

Oh and I can hear the injectors pulsing (I think) when I spun the thing with the drill motor. Is it a worry to push too much gas in the cylinders.
