It is necessary to disconnect 24x crank sensor in order to ensure that 7x signal is read in 3x reference parameter.

5

Use a 5 percent saltwater solution in a spray container to induce voltage arcing to ground through faulty insulation of spark plug wires.

7

If no spark condition follows suspected coil, that coil is faulty. Otherwise, ignition module is cause of no spark. This test can also be performed by substituting a known good coil for one causing no spark condition.
