3rd Gen 4Runner: Turn the key: click or nothing, engine won't crank

Checks, in order

1. Battery voltage
   Resting voltage should be about 12.4 V or more. Under 12 V, charge and load-test the battery before chasing anything else.
   easy $ · under about $50
2. Terminals and grounds
   Clean and tighten both battery terminals, the engine-to-body ground and the starter cable. Corrosion can mimic a dead battery.
   easy $ · under about $50
3. Shift position on automatics
   Try starting in Neutral. A worn neutral safety switch can block cranking in Park.
   easy $ · under about $50
4. Clutch switch on manuals
   Press the clutch fully and listen for the start relay. A failed clutch start switch will stop the starter from engaging.
   easy $ · under about $50
5. Starter
   A single click with a good battery usually means a worn starter solenoid or starter. Bench test or replace it.
   medium $$ · about $50 to $500
