Your starter is the motor that cranks the engine when you turn the key. It only runs for a second or two each start - but when it fails, you're going nowhere. Here are the 6 most common warning signs and what replacement costs.
A single loud click (or rapid clicking) but the engine doesn't crank. This is the #1 starter symptom - the solenoid engages but the motor can't turn the engine.
A harsh metal-on-metal grind means the starter gear isn't fully engaging the flywheel. Left alone, it can damage flywheel teeth, turning a $400 fix into a $1,500 one.
It starts fine 9 times out of 10, then nothing. Tap the starter with a hammer and it works again. Worn motor brushes or contacts cause this.
The starter sounds like it's straining or barely turning the engine. Usually battery first - but if the battery tests good, it's the starter.
Burning electrical smell or visible smoke means the starter is drawing too much current and overheating. Stop trying to start - you can damage wiring.
The car starts cold but won't crank again after a 10-minute stop on a hot day. Heat soak makes a marginal starter quit until it cools.
Symptoms overlap between parts. Run through these checks before spending money on parts:
Starters on inline-4 engines are usually easy to reach. V6/V8 starters often live under the intake manifold (Toyota, some GM), which can double labor.
If you can reach the starter, it's a 1-2 hour job: disconnect battery, remove 2-3 bolts, swap parts. The hard part is access and supporting the heavy motor as you remove it.

Once it's started, the starter is out of the loop - the engine runs fine. The problem is the next start: you may not get one.
If headlights are bright and the dash lights up normally but the engine won't crank, it's the starter. If everything dims when you turn the key, it's the battery.
Rarely. Starters either work or don't - they don't typically pull current with the key off. A parasitic drain is almost always something else (relay, alternator diode, accessory).
