WHen you used the test light on the SPOUT wire (pink), the engine would not even crank? That's not right - it should still crank but might not fire because your timing advance is off (the SPOUT voltage helps regulate timing advance).
Use a meter on your SPOUT wiring and let us know what it is. It should be around 1/2 battery voltage, give or take (Guero is an expert on this stuff too).
Good luck.

It's quite an interesting problem. Without SPOUT voltage readings (spout in vs out), we can guess that the SPOUT circuit works (you'd know if you were running at locked 10-14*). When you put the SPOUT in, can you hear the idle increase (indicating the timing is being advanced)?
Based on the info in your last post, I'd wiggle test the wiring. Also, put your timing light on other cylinder wires if you havent. See if it works SPOUT in and SPOUT out.
And the SPOUT voltage directly correlates to the ignition advance. As I recall, it's linear (higher SPOUT voltage = higher timing advance).

If you're sure about what's occuring with the misfire scenario, I would:
use a noid light (5 bucks or so at the parts store) to see if the same cylinders with no spark also have no injector pulsing. If so, find a friend with a spare computer and see if this fixes the issue.
In general, if a car runs with the SPOUT out but not (at all - the scenario I know) with the SPOUT installed, that's generally a computer issue. Not to say it is a puter issue for sure, but it is something to remember.
Having the misfire occur like that also kinda has me wondering about the TFI module. I've never seen one fail like that however.
