In order for the engine to "turn over" the turning starter gear must engage the engine (typically its flywheel) in order to turn it. That is typically accomplished by a solenoid mechanism that thrusts the turning gear upon its axial drive shaft into the engine's "turn over" ring gearing. The whining sound you refer to could be the starter and starter gear turning but not engaged to crank the engine: failed solenoid. It could be the starter refusing to turn, either jammed in the engine crank ring gear or simply a failed starter motor. Since the sound you hear indicates the current is in fact flowing to the starter motor, there is nothing that needs to be "wired around/bypassed" in order to energize the starter motor. So best guess without looking is starter motor failed or solenoid failed. Often both require the same fix; or its only logical to repair/replace both at the same time--because who wants to do or buy teardown twice if the second fails shortly afte the first.
When the starter drive gear, the starter bendix, goes bad, when you turn the switch to crank the engine the starter will just spin and not engage the drive gear. Replace the bendix on the starter.
Likely either the starter or solenoid. Solenoid is a combination of relay and actuator, pushing the starter's gear into engagement with your flywheel.

starter drive might be bad... fly wheel bad spots poss bad starter you sure its not just clicking???

Three things are needed to cause firing of fuel in cylinders to cause the engine to run. Fuel, Air and spark in the cylinders.
1. Fuel sprays into cylinder during downward piston cycle
(intake stroke)
2. Air drawn into cylinder during downward piston cycle (intake)
3. Spark in cylinder near end of upward piston cycle
(compression)
4. Explosive combustion pushes cylinder piston down
(power stroke)
5. Valves open to remove exploded cylinder gases
(exhaust stroke)
Engine turns over but won't start:
1. Check for spark.
a. if spark not OK, remove distributor cap and verify distributor rotor rotates when engine start attempted
b. If rotor rotates OK (timing belt OK) check for proper voltages
to the coil
c. if rotor doesn't rotate, have it checked out/repaired by a qualified mechanic
2. If sparks OK, check for fuel to injectors
3. If fuel OK to injectors, verify fuel sprayed by injectors
4. If fuel sprayed by injectors, check spark timing
5. If spark timing OK and nothing found out by now, have it
checked out/repaired by a qualified mechanic

TOYOTA IS NOTORIOUSLY KNOWN FOR BAD STARTERS!!!! OPEN THE HOOD AND HAVE SOMEONE CRANK THE STARTER WHILE YOU LOOK TO SEE IF THE ENGINE IS ROTATES, WHEN THE STARTER IS ON.
IF THE ENGINE TURNS VERY SLOWLY OR NOT AT ALL, THE ENGINE IS FINE. BUT, THE STARTER HAS A BAD SOLENOID AND IT'S NOT ENGAGING THE FLYWHEEL. THERE FOR IT'S SPINNING AT VERY HIGH SPEED MAKING A LOUD HI-PITCH WHINNING. BUY A NEW SOLENOID AND FIX IT YOURSELF!!! BUT TOYOTA WON'T SELLL YOU JUST A SOLENOID BECAUSE THEIR GREEDY!!! A NEW STARTER FROM TOYOTA IS AROUND $350.00. AT AUTOZONE AROUND $100.00 WITH A LIFETIME WARRANTY! BUT IF THE SOLENOID SWITCH IS BAD IT COST AROUND $250.00 AT TOYOTA, & $99.00 AT AUTOZONE. ALSO CHECK THE THE STARTER RELAY, COST ABOUT $150.00 AT TOYOTA AND AROUND $40.00 AT AUTOZONE. PULL THE STARTER OUT AND GET IT TESTED AT AUTOZONE...( FREE!!!)
" I'M ABOUT 100% SURE YOU STARTER IS BAD!!!!" GOOD-LUCK!!!
A no-start condition can occur with several different symptoms. Have a clear understanding of which one applies to your vehicle when having the problem diagnosed.
