Check fuses under dash upper right corner. Or by battery for corrosion. Should be only 4. If good then check distributor for power with key on. If power at 2 wires is present + and neg 12 volts. and no spark still. Possibly the control module or ignitor failed. Cap and rotor fine. Check the plug connector going into distributor
Black wire breaks at siliconed green plug from vibration. Have you pulled plug wire and watched for spark jump while cranking? If no Power then check battery leads should be 2 wires to starter and or alternator. Look for blown fuse link on that line.
Key switch maybe another possibility. Cranks fine but had them short out as well And no spark. All light symbols work on dash. May have to check harness plug under dash for corrosion also.
