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.
