A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start.

How do timing chains work?

The timing chain transfers energy from the crankshaft to the camshaft by wrapping around gears mounted to the ends of the two shafts, which the chain uses to grip the shafts. The sizes of the gears create a reduction of rotational speed that causes the camshaft to rotate at exactly half the speed of the crankshaft.
