Replaced already, coil, distributor, ICM, plugs, and wires. I have 12 Volt at coil with switch on, and 12 volt at #4 terminal on ICM. I have an Actron CP9015 Scanner which I hooked up and tried the KOEO test, but nothing, no flashes, no codes. All fuses good, all fusible links good, Fairly new battery with good charge. Engine turns over, but no spark. Computer Bad maybe???
