Today I found a small connection glitch on the prop controller. It has been fixed and performs beautifully. I swapped the Ignition coil and the problem remains the same. Lots of head scratching and web surfing. Advice has been to make sure and clear and error codes that might exist in the ECM. I will do this tomorrow with the OBDII and hope this helps. If not, then I would suspect the ECM itself. Fingers are crossed. The secondary circuits checked out properly at 12.8K ohms. The primary seems wrong at 2.85 Said to be in the range of .3 - 1.5 Voltage wise the primary supply wire has 4 terminals. 12.1v 0.0v 4.65v and 0.0v The second (used) ignition coil I picked up also had similar readings so I am assuming them to be within range. It appears that the coil pack has 2 circuits firing 2 plugs at a time. One on compression and one on exhaust.
