Last night my wife came home and told me that the car was making some whirring/whining sound with the engine turned off and no key in the ignition. She also said that on her way home the engine died at one time, but she was able to restart it without problems.
Sure enough, when I went to look at it, I could hear the sound loud and clear, coming from what I believe is the starter. No key in the ignition and engine turned off. I had to disconnect the battery to stop it.
The car is a 1997 Acura CL with about 235K miles on it. Maintained regularly and never had a serious problem.
This morning I looked at it again. It did not make the sound immediately when I re-connected the battery cable, but as soon as I turned the key to turn on the ignition, the sound would return and the engine would not start, not even a click. Instrument lights would kind of go on and off and when I removed the key the sound continues. Again, I had to disconnect the battery cable to make it stop.
Now when I re-connect the battery cable the sound returns right away with no key in the ignition.
It seems to be coming from the starter because I can feel vibration coming from it, but I can’t figure out why that would be with no key in the ignition. Before I start replacing stuff I wanted to see if anyone here has had similar experiences and how it was fixed. Battery voltage is fine. No engine code is set.
Seems I can’t attach video clips, so I posted it on youtube: https://www.youtube.com/watch?v=DoGxn8dBXBs&feature=youtu.be
