AFAIK the inductance of ignition coils are quite high and so the SRF is very low.
So put the oscilloscope trace first to 100ms/div and see if you get at least the beginning of a sine-wave.
You can also use smaller resistors like 1 Megohm because of the very low frequencies.
An ignition coil has a primary and a secondary coil.
Try both separately (and measure beforehand if they are still OK with a multimeter in ohms-mode).
