'88 325 Fuel delivery problem,..

Ok, the stalling problem is now over. The car just cranks and won't
start, so at least it's not an intermittent fault and it's in the
driveway.
I have spark. Fuse 11 is good. I have battery voltage at term 30 and
86 on the main relay. I can light a test lamp at the main relay r/w
wire by turning the key on with the air idle stabilizer valve harness
disconnected. I have voltage at term 30 of the fuel pump relay. If I
pull the FP relay and jump term 30 to 87 I still can't start the car.
This should hot wire the fuel pump, if I'm following things correctly
and jumped the right wires.
With the relay plugged in I test for voltage between term 85 and 86
while turning the key on. I get no voltage- which is a fault condition
but I don't see where the fault is. That's as far as I got today.
What's the next logical thing to try? If I have to test at the
Motronic brain thing behind the glove box I'm disconnecting the main
harness and probing the connectors not the computer, right? You're
really testing the wiring and sensors, not the chip, right?
For those of you joining our program already in progress, this is a
continuation of the "325 dies under way" thread.

Thanks as always.
