94 corvette backfiring after optispark change
94 corvette backfiring after optispark change. I noticed that the shaft has a notch and only goes on one way but what else could it be? I also replaced the icm with a cheapo from Amazon and installed an msd blaster coil. Might try and put those back? I don’t know what I did wrong

ok I rerouted the spark plugs correctly. I drove it alil and rumpled on it a few times and now it dies on me. I unplug the ecm and plug back in and it starts for 5 secs then dies…
I really don’t know what it is… could it be fueling?
