...and (I think) no signal to either injector as well. (Plugs appear to be dry after trying to start). Have confirmed continuity from ECM connector to Coil connector and injectors for all wires. Have confirmed trigger signal to front coil, and resulting adequate spark at plug. Have confirmed no signal to rear coil. Have confirmed 12VDC to injectors, coil, solenoids, etc. Have confirmed grounds. Battery output, ECM power, check engine light, etc., all appear to be normal. Bike will try to start on front cylinder if I prime it with a little gasoline.
Do not have access to Scanalyzer this week, but will next week. Have not confirmed that no codes are present, but check engine light does not indicate that any are there.
This is the part number ".......97" service replacement ECM with the 43mm flash. Been in there since 1998. All PCIII, etc., are out of the circuit during diagnosis.
Note one unusual thing about this ECM: I no longer have a rev-limit, indicating that some sort of problem is occuring in the ECM--may or may not be related to the no-spark. I was out on the street "playing" one day and revved beyond 6900 RPM. I confirmed this later reviewing the data log. I'm trying hard not to have any preconceptions about a bad ECM causing the no-spark problem, but I'm beginning to suspect it.
Any ideas? Anything else I can check without a break-out box and test leads?
