Alternate method using a voltmeter from the archives but not as accurate as
with
a scanner capable of resetting the sync:
Connect a voltmeter to the distributor sensor connector by removing the end
seal and carefully back probing the connector.
Connect the positive lead to the sensor output pin (pin 3, either a tan wire
with a yellow tracer or a gray wire, depending on vehicle application).
Connect the negative lead to the sensor ground pin (pin 2, a black wire
with a light blue tracer).
Rotate the engine clockwise as viewed from the front, until the number one
piston is at Top Dead Center (TDC) of the compression stroke. The timing
mark on the vibration damper should line up with the zero degree (TDC) mark
on the timing chain case cover.
Continue to rotate the engine slowly clockwise until the V6 or V8 mark
(depending on engine type) lines up with the zero degree (TDC) mark
on the timing chain case cover. The V8 mark is 17.5°after TDC and
the V6 mark is 147°after TDC.
NOTE: DO NOT ROTATE THE ENGINE COUNTER CLOCKWISE. IF THE
ENGINE IS ROTATED BEYOND THE MARK, RETURN TO STEP 2 AND REPEAT THE
PROCEDURE.
Loosen the distributor clamp bolt.
With the ignition switch in the ON position, rotate the distributor slightly
in either direction until the voltmeter switches between the sensor
transition point
of 0 and 5 volts.
Adjust the distributor as close as possible to either side of this
transition point and tighten the distributor clamp bolt to 19-26 N-m
(170-230 in.lbs.) .
