Turning the ignition and getting only silence instead of the engine cranking over is incredibly frustrating when you're sitting in your motionless Chevy. A Chevy that won't start will leave you immobilized and uncertain about the cause. The good news is that a number of familiar culprits make an Aveos fail to start, and you can fix a lot of them yourself or with a mechanic's assistance.
In this comprehensive guide, we're going to look at the fourteen most common reasons your Chevrolet Aveo doesn't start and offer useful tips to get your car started again.
The most common cause a Chevrolet 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.
Signs of a dead battery:
- Silence upon turning the key – no clicking or turnover
- Accessories not powering on
- Difficulty starting in cold weather
How to Fix It: Keep jumper cables available in case of a dead battery emergency. Jump starting your Chevy Aveo using a good battery or portable charger can deliver enough juice to get it cranked.
You can also clean corroded battery terminals if they prevent a good connection. If problems continue, have your battery tested – it may need replacing if old.
If your battery tests fine but your Chevrolet Aveo still won't crank, the issue may be a faulty alternator. This vital part charges your battery when running and powers the electronics.
Signs of a bad alternator:
- Battery warning indicator illuminating
- Electronics dimming
- Difficulty starting, especially after short trips
The Fix: Get your alternator checked immediately by a mechanic. A bad alternator can rapidly deplete your battery. This will need to be replaced by an experienced mechanic.
Faulty Spark Plugs
Spark plugs fire the air/fuel ratio in the cylinders to power your car. When they are fouled or worn out, your Aveo may not start due to no spark.
Signs of bad spark plugs:
- Poor fuel economy
- Rough idle
- Engine misfiring
The Fix: Spark plugs need periodic replacement as they wear out. Most last 30k+ miles. Have your plugs checked and change any faulty ones. Using quality gas prevents buildup.
Issues with parts like the switch, lock cylinder, fob, or wiring can prevent your Chevy from starting.
Signs of ignition trouble:
- No noise upon turning key
- Instrument panel malfunctioning
- Key won't turn
The Fix: For fob issues, try the battery. For other problems, have the system inspected and fixed professionally. If you need a new Chevy key fob you can get one online here.
The starter motor engages when you turn the key to start the engine. If it's worn out, your Chevrolet Aveo may not turn over.
Signs of a bad starter:
- No noise upon turning key
- Clicking but no turnover
- Unusual grinding or whining
The Fix: Have your starter inspected and repaired if faulty. This requires the help of a professional mechanic to diagnose and repair.
Transmission Not in Park/Neutral
If your gearbox isn't in Park or Neutral, your Chevy's safety features will prevent it from starting.
The Fix: Shift into Park/Neutral and try once more. If it only starts in one gear, you may have a faulty neutral safety switch needing repair. This will need to be repaired by a local mechanic near you.
Blocked or Clogged Fuel Filter
A blocked fuel filter can constrain fuel delivery to the engine, preventing your Chevy Aveo from turning over.
Symptoms of a clogged filter:
- Hard time starting
- Engine misfiring
- Decreased fuel economy
The Fix: Replace the filter per your schedule or if thought clogged. Use quality gas and change often. You can have a local mechanic repair this for you, or repair it yourself, maybe with the help and guidance of an online mechanic.
Faulty Fuel Pump
The fuel pump transfers gas from the tank to the engine. If it fails, your Chevrolet won't start due to no fuel.
Signs of a bad pump:
- No pump noise upon turning key
- Difficulty starting
- Stalling when running
The Fix: Have your pump tested. If faulty, a mechanic near you will need to replace it.
Proper compression is required to combust the air/fuel mixture. Low compression from damage can lead to a no start.
Signs of compression issues:
- Difficulty starting
- Rough idle
- Lack of power
The Fix: Testing can confirm low compression. For diagnostics and carrying out this repair, a local mechanic is usually needed and will have to replace the worn engine components.
Timing Belt Failure
The timing belt keeps the camshaft and crankshaft. If it snaps, the valves and pistons aren't synchronized properly and your Chevrolet Aveo won't start.
Symptoms of a bad timing belt:
- No start
- Unusual ticking noise
The Fix: Have your belt checked and replaced immediately if broken. This requires a local professional mechanic to replace the timing belt of your Chevy Aveo.
Detached or Loose Battery Cable
Symptoms of a bad cable:
- Corroded terminals
- Power loss from moving cables
- Frayed wiring
The Fix: Clean corroded terminals and tighten loose connections. Damaged cables need replacement. You can get expert Chevy mechanic advice and guidance online or with a local mechanic.
Relays control power to components like the starter, fuel pump, and computer. Failure can prevent your Chevy Aveo from starting or running right.
Identifying relay problems:
- Swap relays to test
- Have relays checked by a mechanic
The Fix: Faulty relays must be replaced, often after a larger diagnostic. You will likely need a local mechanic to diagnose if the faulty relay is preventing your Chevy from starting.
Empty Gas Tank
Running your tank bone dry can cause a no-start due to lack of fuel. This seems obvious however it often happens because of an inaccurate or broken fuel gauge.
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.
Sometimes an engine can flood with too much fuel, preventing starting due to wet spark plugs. This is most common in older carbureted engines.
The Fix: Press the gas pedal fully and crank briefly to clear the system so the plugs can spark. If problems continue, have the carburetor adjusted by a professional local mechanic.

FAQs (Frequently Asked Questions)
Why is my Chevy car not cranking but I have power?
If your Chevrolet won't start but the accessories and dashboard power on, the most likely culprits are issues with the starter motor, ignition switch, or neutral safety switch. Faulty ignition components prevent the engine from cranking even when battery power is present.
Why does my Chevy have power but won't turn over?
When your Chevy has power to the lights and accessories but won't crank when trying to start, the problem is often a bad starter motor or related wiring issue. This prevents the starter from activating to turn the engine over for starting.
What would make my Chevy car unexpectedly 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 urgent issues can arise without warning and prevent your Chevy's engine from starting.
Why won't my Chevy car start but the battery is fine?
With a good battery, the problem may be a faulty alternator not charging the system, bad spark plugs providing no ignition, or a fuel delivery issue preventing combustion. Your Chevy's engine needs air, fuel, compression and spark to run.
What are signs your Chevy starter is bad?
Signs of a bad starter include no noise when turning the key, a single click but no turnover, unusual grinding sounds, and difficult cranking. These indicate starter failure and the need for replacement by a local mechanic.
Why won't my Chevy car start but battery and alternator are good?
