Remove your coil pack.
Check the specs of your car in a service manual to find out what the primary and secondary range of resistances are. If you don't know, just write down all of your numbers and see if one is way off.
Turn on your meter and touch the center prong on the coil pack electrical connector with one of the meter test leads, and touch the corresponding coil prong on the electrical connector with the other test lead, this is the primary resistance.
Now touch the spark plug wire terminals on one of the coils with the meter leads. This checks the secondary resistance.
If any numbers are way off in their similar sets, its bad. Secondary results will most likely be in thousands of ohms, while the primary will realistically be under 10 ohms.
