engine turns over, will not fire

I like to follow a path of simple diagnostics when faced with an issue like this.

Does it have spark out of the coil wire?
No. go backwards into the system from there
Yes. go farther down stream from there.

If it does not have spark, then does the coil have power to it?
No. find out where the interuption is.
Yes. see if it has a signal from the system to fire the coil?

If there is spark from the coil, then does it have spark at the plugs?
No. then it's the distributor reluctor, rotor, distributor drive, cap, wires or plugs.
Yes. then it's a timing problem or something else not related to the ignition system at all.

Any way, that's the way I go about diagnosing.
