Just like the Toyota diagnostics 'said',it was the ECM all this time.
SIA's Michael phoned to tell me that he'd missed one trace when he had the ECM the 1st time.Under high magnification it showed up.He apologized for the inconvenience.
SIA honored their warranty,including shipping.
I plugged it in,bolted it to the kick panel and the engine fired immediately.
The Scan-Gauge/ Toyota codes were spot on.

I bought a pair of 'low' ramps to help when pulling the belly off,in anticipation of the trip to the muffler shop.They'll travel with me on the trip as well.
The parking brake control cable snapped,probably due to it's sodium chloride joyride at Bonneville.After I leave here today I'll look into that.
'Get through inspection and registration and she'll be mine to drive for another 11-months 'til next go-around.
Then get back to fabrication which is backed up quite a bit now.
