Drained or Dead Battery in a Chevrolet Alero

The most common cause a Chevy won’t start is a dead or weak battery. Your battery supplies the initial burst of electricity to turn over the engine and get it running.

Indications of a dead battery:

  • Silence upon turning the key – no clicking or turnover
  • Electronics not powering on
  • Difficulty starting in cold weather

The Fix: Keep jumper cables on hand in case of a dead battery situation. Jump starting your Chevrolet Alero using another vehicle or jump box can supply enough charge to get it started.

You can also clean dirty battery terminals if they prevent a good connection. If problems persist, have your battery tested – it may need replacing if worn out.

Bad Alternator in a Chevrolet Alero

The Fix: Keep your tank at least 1/4 full to avoid unexpected emptying. If issues persist, have your fuel sender unit checked by a professional mechanic.

Engine Flooding

The Fix: Press the gas pedal fully and crank briefly to flush the system so the plugs can spark. If problems continue, have the carburetor adjusted by a professional local mechanic.

FAQs (Frequently Asked Questions) When a Chevrolet Alero Won’t Start

Chevrolet Alero won’t start but lights turn on?

If your Chevrolet Aleros lights turn on but it still won’t start, the issue may not be related to the battery. More than likely there is a problem with the engine starter. Investigate if you hear any clicking noises when trying to turn the key. If so, the starter motor is trying to engage but failing. Have a mechanic examine the starter motor – it may need to be repaired or replaced.

Chevrolet Alero won’t start but has power?

When your Chevrolet Alero has power (lights, radio etc work) but does not start up, there may be a fuel delivery problem. Issues like a faulty fuel pump relay could prevent fuel getting to the engine. Without enough fuel, combustion can’t happen and the engine won’t start. Listen near the back seat when cranking the key – you should hear the fuel pump prime for a few seconds. If not, get a mechanic check the fuel system.

Chevrolet Alero won’t start but battery is good?

If your Chevrolet Alero’s battery checks out OK and is fully charged, but the car still refuses to start, the underlying cause is likely electrical. Possible issues include a bad ignition switch, broken sensor, or wiring problems. As electrical issues can be tricky, diagnosis by a professional mechanic is best. They can accurately identify the specific electrical fault and have it repaired.

Chevrolet Alero won’t start just clicking?

When you turn the key and there’s only a clicking noise but the engine fails to turn over, the most common cause is a faulty starter motor. The click comes from the starter solenoid trying to engage the starter motor, but the motor itself fails to spin up the engine. As the starter motor needs mechanical repair or replacing, seek help from a reliable mechanic to get your Chevrolet Alero running again.

Why is my Chevrolet Alero car not cranking but I have power?

If your Chevrolet Alero won’t start but the lights and electronics come on, the most likely culprits are issues with the starter motor, ignition switch, or neutral safety switch. Defective ignition components prevent the engine from cranking even when battery power is present.

Why does my Chevrolet Alero have power but won’t turn over?

When your Chevrolet Alero has power to the lights and accessories but won’t crank when trying to start, the problem is often a bad starter system or related wiring problem. This prevents the starter from engaging to turn the engine over for starting.

What would cause my Chevrolet Alero car suddenly not start?

Sudden no-start issues can happen from disconnected battery cables, fuel pump or relay failure, broken timing belt, or an empty gas tank. These critical problems can arise without warning and prevent your Chevrolet Aleros engine from starting.

Why doesn’t my Chevrolet Alero car start but the battery is fine?

With a good battery, the problem may be a bad alternator not charging the system, bad spark plugs providing no ignition, or a fuel flow problem preventing combustion. Your Chevy’s engine needs air, fuel, compression and spark to run.

What are symptoms your Chevrolet Alero starter is bad?

Signs of a bad starter include no noise when turning the key, a single click but no cranking, unusual grinding noises, and difficult cranking. These indicate starter failure and the need for replacement by a local mechanic.

Why won’t my Chevrolet Alero start but battery and alternator are good?

If the battery and alternator check out, common causes are bad spark plugs, blocked fuel filter, blown fuse, immobilizer problem, and starter relay failure. Complete testing of all electrical and fuel systems is needed by a qualified local mechanic.
