Can only be:
no petrol or an electrical fault = flat battery, no spark, electrical short, bad wiring.
a bad engine

If the oil is low in your car, it can eventually cause your car to stall and not start. It can also kill your engine.
Probably not, although it could lead to other problems which would cause your car not to start.
Repeated attempts to start a car will not hurt a car as long as the engine has the oil it's supposed to have. However, they aren't good for the battery.
Will cause engine damage If large amount in tank car will not start or run
Engine mounts
Yes, a bad coil will prevent the ignition from firing and the engine will not start.
The car will start and run poorly in the limp mode and the check engine light will illuminate.
Could be fuel or electrical problem. Does the car start and run okay the first time you start it? Does the engine run smoothly under load?
Well there are many different things that can go wrong with and engine and make them bad or "fried" as you put it. A few vague examples are: -If the engine is seized up it will not start. -If it does start up but knocking then it needs to be taken to a mechanic. Driving a car that knocks will only cause further damage. -A car with a blown head gasket will start and run usually but will overheat and cause further damage such as warping of the heads. If a car doesn't start it doesn't necessarily mean that the engine is "fried". There are many possibilities for why an engine will not start. Look up "no start" situations for the car make and model. Hope this helps.
Engine is flooded. Too rich a fuel mixture will cause the engine to stall. Timing could be off as well.
