Some of it may be in my head, but I swear it seems to run a little smoother (it wasn't running 'rough' before). It seems to crank with less effort, meaning that where it used to chug, chug, chug, chug, chug, CRANK it now just chug, chug, CRANKs.
You are going to confuse a lot of mechanics with that kind of talk.
When the starter is engaged......the engine is "turning over".....or "cranking". (The engine is not yet running). This choice of words comes form the days that engines used to be started by hand and using the hand "crank" to turn the engine "over" so that it could be started.
When the engine comes to life....the engine has "started" and is "running".....(not cranking).
I have been fooled by this before, when my wife told me her car would not "turn over". I went out and got my wrenches to see what could have locked up the engine, and when I tried to turn the engine over it rotated fine. Then when I tried the key the starter turned the engine over....but it would not fire ("No Joy".....for our members in the UK). It turns out my wife uses "won't turn over" to explain that it won't start and run.
in my part of the south we (even the mechanics) would say it 'won't light off' or 'won't fire up'
