A test light will prove helpful here and a second pair of hands.

Unplug the 2 wire connector from the coil, Clamp the lead of your test light to battery ground, make sure the light works.

Have helper turn ignition on while you probe the coil connector for power, one wire should be power.

Note, you need the helper to cycle the ignition on and off since the ASD relay turns off after about 2 seconds if the engine isn't cranked.

After you verify which wire is power, rearrange the test light so its clamped to battery positive. Probe the other wire at the coil connection. The test light should flicker as the engine is cranked.

OK so the possible bad outcomes:
No power found at coil= broken wire between ASD relay and coil, possible bad fuse or other bad connection.

No flicker of test light, 2 possible directions.
Light never turns on= broken wire between coil and PCM, possible failed PCM. Likely bad or no signal from crank sensor.
Light stays on constantly= short to ground between coil and vpcm or dead PCM. This can be found by unplugging the PCM, if the light goes out the PCM is shorted.

If the testing at the coil connection is as described above (power steady and flicker on the other wire). Your problem is between the coil and plugs, including plug wires cap and rotor.

What happened right before it quit running?
