I would open the case of the ECU and check pin #1 from inside
provided that you have done checking from outside. If you have
a digital VOM you can measure AC voltage on pin #1 from inside.
Start from a higher range then switch to lower range until you
get a reading. You should see a few volts up to 10 or 15 volt.
If it is zero that apparently means trouble there.
----IM GONNA GO TRY THAT NOW. SOMETIMES WHEN ONE HAS BEEN STUCK ON A PROBLEM FOR A WHILE,
THE OBVIOUS IS OBSCURED
If you have a scope it will be the best tool to see the signal.
--A SCOPE???

Check all your ground strips. It could be a grounding issue.
---REGROUNDED ALL GROUNDS, REAR COMPARTMENT, ENGINE BLOCK, TRANNY, BATTERY,
If you can find an ECU to try it will tell if it is the culprit.
---IN THAT PROCESS, BUT ILL CHECK ECU #1 FROM INSIDE -OR- THE BACK OF THE ECU CLIP FIRST
Or you can take your ECU to try it on another van.
HARD TO FIND AN 82 ROUND HERE.
