Fully exposed underneath to all kinds of environmental contaminants like the salt used on Midwestern roads in winter, it finally succumbed hence stopped grounding the solenoid. Seems this factor had some effect on the CANBUS electronics that also disabled the ignition system so even bump-starting this 6-speed manual equipped vehicle was rendered impossible.
Not familiar with your car, but two things I am pondering:
1. Did you ever successfully try bump starting it before the wire in the starter failed?
2. Isn't the starter solenoid, wire or not, still grounded via its mounting to the actual starter?
