There was another thread in tech with the exact same car and issue you mention.
If the points are cooked then its best to check the primary resistance of the ignition coil - if its too low it will seriously harm the points and even fry them in a matter of minutes.
a pretty basic points ignition diagram is this and is pretty similar in every car
The only one or two different ones were e.g. GM who dont use a dedicated resistor but have a resistive wire in place of it. If you are in a pinch to test it - head over to a Jyard and nab a denso coil from an old toyota and test it - if the coil you find is a red cap do not connect it directly - you need a step down resistor for it.
