Correct, just a quick reality check to make sure the tacho wire is not shorted to earth somewhere. Set the multimeter to 2000 NOT 2000K as that is actually 2000 000 (2M).
Ignition off and on the tacho side of the suppressor (ie the side going to the car not the side going to the ignition coil). I am assuming this will be a fairly high value however if it is not it might help you to isolate an issue.
BUT - if you do have spark I suspect the issue may be the suppressor.....
If you do not have spark the issue is likely the ignition amplifier.
Does the car run if you short out the fuel pump relay like it was when you bought it?
