Still trying to troubleshoot my starter solenoid issue. When turning the
key to start, the solenoid engages about 50% of the time, more when the
engine is warmed up. All connections are sound, clean & shiny. I've
already replaced the ignition switch, so that shouldn't be the issue.

In my limited experience with starter solenoids, they either work or they
don't...very little in between. Anyone have a similar experience with
starter solenoids, or can suggest where to check next?

This is on a 1999 Maxum with a 4.3L GM V6. I have heard/read that starters
and/or solenoids are notoriously bad on this model engine.

Thanks,
Mike
