Chrysler Repair: 93 town and country, code 43

Question
I am working on a 93 town and country and have a code 43, Ign coil 3 primary circuit. I have tested the circuit according to the Chrysler manual, replaced the coil, substituted a known good PCM, checked primary wires and spark plugs. have 12 volts from the asd relay, no ground shorts, no opens, and now am extremely frustrated. Please HELP!

Answer
Hi Bryan,
If the code 43 was obtained by the ignition key approach, let me mention that code 43 does not uniquely point to the #3 primary circuit but also to #2 and #1. So you may well want to check all the three circuit wires and plugs related to the primary windings of the ignition coil if you have not already done that. Is it obvious as to which plugs are not producing good quality sparks? Might you be misreading the check engine light flashes if there is no noticeable problem with how the engine is performing? I assume this is the 3.3L engine.
Please read the PS (below) and respond to it.
Thanks for doing that.
