Ok, following the digifant tests in Bentley 25.61, there are a couple issues so far.
1.   Probably minor - tps when fully open, infinite resistance.  The other ranges are fine.   Would not effect start.
2.  Air flow sensor.   Different results w and w/out syndrome wire.   W/out, resistance moves w the changes in the vanes.  With the wire, it doesn't seem to move.  Car didn't start w or without it.
3.   This may be something.  Step 5, injectors.   Resistance is infinite between pins 12 and 14.   Resistance on a specific injector does fall in the correct range.  I'm testing this with ignition off.
Pin 12 is for the injectors, pin 14 is for the digifant control relay.
Maybe one of the relays is flaky.   Either the fuel pump relay or the control unit relay since they seem to be intertwined.
I am confused by wiring diagram 97.206 (1990 bus).   Do all injectors fire at the same time?
