Looking at the diagram, it shows ***only the green wire that goes from the
Idle Stabilizer Valve Control Unit(ISVCU) terminal 17/1 is connected to Coil
terminal 1***.  The other segment on ISVCU 17/1 is shown to go to the
autocheck controller.  Therefore, the diagram does not show a control signal
feed that comes directly from the ECU that aught to go to the coil terminal
1.  So it a appears the problem is I am missing this feed, or it is not
being enabled or passed through ISVCU or other means.  Is ICU that Tony
refers to the same as what I am Calling the ISVCU?

OK, the ICU I refer to is the ignition control unit that mounts inside the
DRIVERS side kick panel on the 5k. I'm not sure if it is there on a turbo.
Yes, there should be some sort of signal running from the ECU to the coil,
but until I look at the schematics, I don't know which wire this would be.
And, I would sure hope the ISV isn't where the signal comes from.
