For fairly exacting instructions for testing the 91 Accord's ignition coil,
see www.autozone.com. Put in your model's info, click on the links to the
FREE repair guides, go to Engine Electrical, Electronic Ignition, Diagnosis
and Testing. There you will see the following and more:

See Figure 16

The ignition coil is contained within the distributor. With the ignition
OFF, remove the distributor cap.

Remove the screws securing the black/yellow wire and white/blue wires from
the terminals. The black/yellow wire is connected to the primary positive
terminal and the white/blue wire is connected to the primary negative
terminal.

Measure resistance between the terminals. Resistance should be between
0.6-0.8 ohms.

Measure the resistance between the primary positive terminal and the
secondary terminal. Resistance should be 12,800-19,200 ohms.
