Okay so here's the status:

Turn the key - Fuel pump cycles momentarily - Starter does nothing.

Aside from the battery cabling, which we are very confident in, the only thing I'm seeing in the wiring diagrams that might interfere with the starter signal is the clutch switch.
We haven't confirmed if the clutch switch is working right or not, but is there any other reason the starter wouldnt be cranking? Is there anything else in the PCM logic preventing a start?

I have an update on this problem, but I'll post it in my build thread.

Prior to tuning, would the lack of a plugged in IMRC prevent the engine from cranking?

No reason to believe that would make any difference at all.

Does anyone know if an O2 sensor missing from the circuit would prevent a startup?

I need a dummy check.
I have a 98.5 PCM in a 99 return style car. This should work, right?
Its an SFG0

Back when I was entertaining the idea of adding an SVT ECU to my 1999, I seem to recall that SFG0 was indeed the one I was looking for. However, all my PRACTICAL knowledge has been with returnless systems, so I'd definitely defer to someone who's been there.

Does anyone know what the engine cooling fan setpoints are?

When I watch the digital gauges, the high speed fan always came on at 226°. Can't hear the low-speed over the engine racket.
