I did a continuity test with the servo motor plugged into the loom and the PGM unit unplugged.

Joe, unplug the servo motor as well and check for continuity among the fitments.
There are four wires on the servo fitment and a separated Lt/Gr and they all end up on the 16pin connectors of the PGM unit.
This will verify if there is a broken and/ or a loose wire at your wiring loom.

You should also unplug the cables from the servo mechanism. If there is a problem, you will risk less to fry the PGM units -if they are still in working condition-. Just let the cables on the exhaust valves and unplug them from the servo mechanism.


Regarding the servo motor.
With the servo unplugged, position the pulley halfway, between "Lo" & "Hi" positions.
Set your multimeter for resistance measurements and check blu/G and lg wires & lg and Y/R wires.
You should read about 2.5Kohm on both readings.
