5th 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. Below 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 ground and the starter cable. Corrosion here gives the same click and no crank.
   easy $ · under about $50
3. Shift position and brake
   Try Neutral and make sure the brake pedal is pressed. A worn neutral start switch or brake switch can block cranking.
   easy $ · under about $50
4. Key fob or push button state
   On smart-key trucks, a dead fob battery can prevent starting. Hold the fob against the start button as the manual describes and try again.
   easy $ · under about $50
5. Starter and solenoid
   With a good battery, a single click or intermittent no-crank is the typical starter failure. Test the voltage at the solenoid terminal while someone turns the key.
   medium $$ · about $50 to $500
