My truck (manual 5-speed, 1999 s10) would not start for me. First the motor started to turn over, then it whirred or whined rather than crank. It whirred/whined as long as I turned the key. I kept trying, but it never started.
I got another driver to give me a boost with jumper cables. Would not crank. Still only whirred/whined.
I only got it started by pushing the truck off.
I tried this morning the same thing. The motor seems to start then the whine/whir and no start. No clicking noise only high-pitched whir.
The lights and windshield wipers all work. The battery is about 4 months old.

if it wont turn over 1st check the ground s on the car and the battery 1st. your battery can be fully charged and the car will not start even over night this can happen. then look at the starter. Note: if you have over 109K on the car and the timing belt has never been replaced you will need to have this checked as well.
- Switch on the head lamps for 5 minutes.
- Keeping the head lamps ON, start the engine. If the lights die,
- Check the battery terminals.
- Check battery state of charge.
- Charging system. If the lights still glow sharply,
- Check fuses and relays in under the hood fuse and relay box junction.
- Battery to starter motor cable.
- Battery to engine ground and chassis ground cable.
- Solenoid on starter motor.
- Starter motor.
Even though all your other electrical bits are working it could be that your battery doesn't have enough juice to crank the engine. It doesn't take much power to run the radio, lights, etc, but cranking the engine requires the battery to have a very strong charge. If your battery is more than 5 years old, that's very likely the issue. I'd start there. Also, be sure to check the battery terminals and ground for corrosion and clean if necessary. If replacing the battery doesn't solve the problem it could be the starter solenoid or a loose electrical connection somewhere.
Do your lights dim considerably when trying to turn over? If so, then your battery may be flat. If your headlights don't dim considerably when energising the starter motor, then it is likely the starter motor which has failed.
It sounds like you have a bad actuator. This is attached to the starter and has a solonoid that pushes the starter motor gears into the engine gear. If the solonoid is faulty this may happen. Also check alignment of the same.
Since you have power to your accessories, here are a few more things to consider:
1: Automatic transmission not in park or the neutral safety switch is faulty
2: On manual transmissions clutch pedal not depressed or or clutch start switch failure
3: Broken or loose wires in the starting circuit. Inspect all wires and connectors at the battery, starter solenoid, and ignition switch
4: Starter motor pinion jammed in flywheel ring gear. Manual transmission. place transmission in gear and rock the vehicle to manually turn the engine. Remove starter and inspect pinion and flywheel
