That depends, each vehicle takes a different amount of time to do all the required self tests.
Fix the cause of the code that turned the light on.
The service engine did not shut your car down, It was the part that turned the light on, (not the computer monitoring system) You need to determine what turned the light on that's very likely what turned your car off.
The check engine/service engine light should come on as soon as the ignition is turned to the on position without starting the engine. If it does not, then the bulb is either blown or has been removed.
Your check engine light will not come on in the auxilary (accesory) position. It comes on when the key is in the on (run) position to check the warning lights just before you start the vehicle.
The engine of what? The car? And usually, everything must be turned off before its safe to remove or install anything.

Yes, the crankshaft main and rod journals can be turned .010", .020", or .030" under and or just polished but it has to be removed from the engine to do so.
It is not supposed to be on when engine is running unless there is a problem.
