You can take a clothes pin and glue some copper foil to make a pick up. Solder a 0.01uF 1KVAC capacitor in series into a coax, and another capacitor from the center to the shield. This builds a AC Voltage Divider such that your scope will be see approximately 1/2 of the kilovolts. Long jumper on the coax shield for the GND. Set your scope for 1M ohm input if selectable. Depending on your scope, triggering can be temperamental. Place on the coil wire and try to see 8 (for a V8) ringing pulses. If you have MSD it will be just a big mess of ringing. If the ringing is not symmetrical then you have a bad plug, wire, distributor port, etc.
