URQ no spark- cont.

[DGraber460 at aol.com]

Many thanks to all who have responded to my previous post for help!

I have tried all suggestions to no avail.
The car is statically set with the flywheel at TDC, and the cam and 
distributor are properly aligned (not 180 out). All the marks are right on, 
including the damper pulley, not just close. During cranking I have rotated 
the distributor slowly through a +180 degree sweep to no avail.
We have 12 volts at pole 15 on the coil with key on. Swapped in coil from my 
car, and still no spark. Swapped coil wires from my car, no change. There is 
no spark at the coil wire distributor end when held close to ground.
Swapped ignition control unit (above glove box)- no change.
Checked 12V and ground pins at ECU- checked good.
Swapped cap rotor and wires- no change.
Swapped entire distributor- no change.
The TDC sensor, and RPM sensor both show signals on cranking.
Performed SM's Hall sender check at distributor connector;
             pole 1 to 2, should show ~4 volts when Hall sheilded- shows 6.46v
             pole 1 to 2, should show 0-.5 volts when unsheilded- shows 10.9v
We thought we had found a possible cause, but the replacement distributor 
showed the same numbers. Any ideas what could cause this?
No spark is verified by a spare spark plug in wire #1.
The battery is new, and fuel checks out.
I've run out of things to change or check. Any help/ideas/suggestions greatly 
appreciated.
We've had a lot of fun working on this baby, but it's time it came to life.
