What causes a petrol engine not to start?

What does it mean when an engine turns over?

The term “turning over” refers to the mechanical process the engine uses to start. That process is the starter engaging the flywheel, the flywheel rotating the crankshaft, and then the crankshaft starting the engine. This is that cranking noise you hear when you turn the key – that fast-paced “ruh, ruh, ruh” noise.
