Man, today was a busy day at work....maybe now I can post some more
Good...you pulled codes. But none of those codes will cause a no-start condition. So either the PCM itself is shot (or flaky...I've seen the circuit traces inside these PCMs and they aint pretty after all this time), or there is something wrong that the PCM just wont see.
After seeing your video, I would like to think your ground buss is a culprit in this. Either that, or your battery just doesn't have the juice it should anymore. Is there a date code on the battery that you can see? It could be a punchcard-type decal, or it could even be a sticker with a letter and a number.
