Fair enough, but a bit hard to describe. I'm not sure if it was turning, if the engine was catching up. I turned the key, and instead of cranking and starting, it just continued to make that screeching noise that usually last only a second or so without it actually starting up. If I were to guess, I'd say the engine wasn't catching up and it was just feeding the starter from the battery. Still, I found it surprising that once started, the engine seemed to function normally. And it is starting just fine if the engine is hot, and with a bit of hesitation an hour or two after driving.
