I had extended the CAS wiring when I replaced the engine, so I decided to reroute the shielded CAS wiring, so that I could eliminate the unshielded wires, which were about 12" long. Same problem.

I am struggling with what to try next. This problem started before I swapped the engine, as it was very hard to get started, though for three years prior to that, I had no issues, and it started easily.

Has anyone else seen this type of problem, or have any suggestions ?Re

Steve,

You may have a marginal ground between the engine and the battery. When cranking, the starter dumps high current through the marginal ground, and the potential at that point rises, If the EC-2 is grounded through the same ground, then This would look like low voltage to the EC-2 and coils, even if the battery terminal voltage was not drawn down much. I would check all the engine ground connections. A little corrosion could build up and cause this effect.
