Well guys, here's the lowdown:

Vehicle: 1993 Montero 3.0 V6 (6G72)


1. I tested all four cables at the dist. sensor plug:

Black: 12V Negative
Red: 12V Positive
White: 11.6V Positive at switched on AND at cranking, no pulsing
Green: 11.6V Positive at switched on AND at cranking, no pulsing


2. Tested both cables that go into the Ignition Coil:
12V at positive
None at negative, and no pulse when connected test light to one and the other

3. I found the ECU test port next to the fusebox, under the driver side dash, and got a CONSTANT 12V reading after switching on. Does this mean my ECU is dead?

4. I swapped the power module (capacitor) that is next to the ignition coil for a known working one, and the engine ran fine for about 10min. and THEN DIED. The ignition coil was sparking perfectly for this period, and just died off.

...AND I have NO clue what's wrong with it, or why it worked fine for a while.

Thanx!
