I would think that the ingion test in mode 8, which simulates running at 3000 RPM's (I think) would be a higher stress than just cranking the engine over. The mode 8 test prduces what looks like good consistant spark, and all coils look the same. I couldn't see any that looked stronger or weaker.

Hi Steve;
It sounds like a coil/igniter is dead or dying.
I've heard several stories where these would pass basic tests but not function properly under load.

I replaced my original engine with another newly rebuilt block, and also added the EM-3 to the installation. The old engine was hard to start, and was also making a ticking noise when it did start, which didn't used to be there.
After several failed attempts, and double checking the connections, I had a neighbor help me do some testing. While the ignition test runs fine, when checking one of the plugs, it sparks when I initially crank the engine, and then stops. Once in a while there will be another spark, but not very often.
I reinstalled the original CAS and have the same issue. I have double checked the CAS connections and checked them with an ohm meter to the connector on the EC-2 also. Everything seems to check out, yet I get only that initial spark. I have replaced the spark plugs with new ones, and whenever I pull one to check it, is is wet with fuel, which is no surprise.
I am wondering if anyone has seen this type of problem, or if you have any suggestions. Regards,
Steve Brooks
