[s-cars] Tach Problem and fault code help

[CyberPoet]

There is one thing comes to mind -- enough force to break a tooth off a
flywheel is usually enough force to actually cause the flywheel to
crack (beyond just the tooth gearing), and that makes for an extremely
dangerous situation. Think of a standing next to a heavy steel wheel
spinning at exactly it's center at 5,000 RPM, and then having that
wheel break into three or more parts -- with how much force is on the
parts to 'depart' tangentially? Now imagine that happening under your
hood at a traffic light... A broken flywheel can be life-threatening
(having seen one disintegrate, and having found several broken but
still retained, it's a wonder it doesn't happen more often).

Meanwhile, if your flywheel teeth are bad (rare, since flywheel teeth
are made out of harder stuff than starter bendix gear teeth by an order
of magnitude normally), then it will be noticeable at starting when
your starter occasionally spins up to high speed and when the flywheel
is at the spot that the teeth are missing/bad, inducing no engine turn
over (ZZZZzzzzz... electrical whizzing sound), or alternatively, what
could be imagined to be the sound of a dead armadillo in garbage
disposal (a horrid grating sound).

If you suspect, it behooves you to inspect :)
