Interminent no start, Interminent no start Options

Began recently - upon a key turn - just warning lights and silence - no starter turning. Next turn may start fine. Battery is new.
No other issues. Happened after running, never cold - but unsure about a connection. Just like - one time there is no
starter connection, next time - OK. Any ideas greatly appreciated. Thanks!

If you were to add hearing a single click when trying to start the car, your symptoms perfectly match those expected of worn starter contacts. $10 and less than an hour to fix.

It's pretty much the only thing that goes wrong with Toyota starters proper (not including the wiring). A starter works in two stages: turning the key to START sends a little power to the solenoid in the starter. The solenoid closes, creating a large enough connection to provide power to the starter motor to turn the engine over.

The solenoid consists of two copper contact plates to which the external wiring attach, and a central plunger which spins with the starter motor. That spinning wears the contacts, eventually creating a half-moon worn spot on both. The problem occurs when the plunger gets caught on the lip of that half-moon. The connection is then too thin to pass enough current to turn the engine over. Trying again, or rapping on the starter in between attempts, can jiggle the plunger and contacts enough that the plunger gets past the ridge and makes solid contact, allowing the car to start.

Sound complicated, but the fix is both simple, and cheap. Pull the starter (takes about 20 minutes), disassemble the starter solenoid (30 seconds), replace the copper contact plates and sand the bottom of the solenoid smooth (takes about 10 minutes), and then reassemble and reinstall (another 15 minutes). The contacts themselves cost about $10.

You should also be able to get the contacts from Toyota, I suggest contacting Lithia Toyota to ensure you get the correct parts.
