Some of the national brand auto parts stores might be able to test the ignition module.

As far as the coil, different manufacturers may have different specs? The only specs I could find were from Wells.

This guide can help.

Coil secondary ohms test 3--10K ohms. Coil primary circuit ohms test .15--.6 ohms.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
