What happens if you turn for key to START when it's already running?

I am wondering if anybody has done this to their car. Does it do anything?

Nasty Noise. But it's hard to hear because the engine is running. :)
Good old learner days i thought i'd stalled on a roundabout :rolleyes:

It files down the gears of your starter motor. Not something you want to do on purpose. :)

AFAIK the car reverses the alternator and tries to start the running engine from the battery resulting in two things.
1) A grinding noise that varies in loudness and ferocity based on the model of car.
2) Possible mucking up of the works of your automobile. A few times probably won't hurt much, but I wouldn't make a habit of doing this to a vehicle you are fond of.

Don't do it for sure. As a general rule, I would say if it sounds bad, it probably is bad or doing damage in some way. It will grind the starter as has been said.

Stuck in the middle with you
I did it once. I thought I had stalled my car so I went to start it up and the sound of 1000 demons erupted from my hood. I let in the clutch and drove off, rather embarrassed.

I did it once and 1000 demons actually errupted from underneath the hood.





I never did it again.
