The silence that fills your inactive Chevy when you turn the key and it won't start can be extremely annoying. A Chevy that fails to start leaves you stranded and clueless about the issue. The good news is that a number of familiar culprits make a Lanoss fail to start, and you can fix a lot of them yourself or with a mechanic's assistance.
In this comprehensive guide, we will examine the fourteen most common causes your Chevrolet Lanos won't start and provide helpful tips to get your car running again.
The most common cause a Chevrolet doesn't crank is a dead or weak battery. Your battery supplies the initial burst of electricity to turn over the engine and get it started.
Signs of a dead battery:
- Silence upon turning the key – no engine cranking
- Accessories not powering on
- Difficulty starting in cold weather
The Fix: Keep jumper cables available in case of a dead battery emergency. Jump starting your Chevy Lanos using a good battery or portable charger can supply enough juice to get it cranked.
You can also clean dirty battery terminals if they prevent a good connection. If problems continue, have your battery tested – it may need recharging if worn out.
If your battery checks out but your Chevrolet Lanos still won't turn over, the culprit may be a faulty alternator. This key component charges your battery when running and energizes the electrical system.
Signs of a bad alternator:
- Battery warning light coming on
- Electronics dimming
- Hard time starting, particularly following 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.
Bad or Fouled Spark Plugs
Spark plugs ignite the air/fuel ratio in the cylinders to run your car. When they are fouled or worn out, your Lanos 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 bad ones. Using quality gas helps avoid buildup.
Ignition System Issues
Problems 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
- Dashboard malfunctioning
- Key won't turn
The Fix: For fob issues, try the battery. For other problems, have the system inspected and repaired 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 damaged, your Chevy Lanos may not turn over.
Symptoms of a bad starter:
- No noise upon turning key
- Clicking but no cranking
- Unusual noises
The Fix: Have your starter inspected and replaced if faulty. This requires the help of a professional mechanic to diagnose and repair.
Transmission Not in Park/Neutral
If your transmission isn't in Park or Neutral, your Chevy's safety features will prevent it from cranking.
The Fix: Shift into Park/Neutral and try again. 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 clogged fuel filter can restrict fuel delivery to the engine, preventing your Chevrolet Lanos from starting.
Signs of a clogged filter:
- Difficulty starting
- Engine sputtering
- Decreased fuel economy
The Fix: Change the filter per your schedule or if thought clogged. Use quality gas and change regularly. You can have a local mechanic repair this for you, or repair it yourself, maybe with the help and guidance of an online mechanic.
Bad or Failing 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.
Symptoms of a bad pump:
- No sound upon turning key
- Difficulty starting
- Stalling after starting
The Fix: Have your pump tested. If faulty, a mechanic near you will need to replace it.
Proper compression is needed to combust the air/fuel mixture. Low compression from worn parts can cause a no start.
Symptoms 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 Lanos won't start.
Symptoms of a bad timing belt:
- No start
- Unusual clicking sound
The Fix: Have your belt checked and fixed right away if broken. This requires a local professional mechanic to replace the timing belt of your Chevy Lanos.
Detached or Loose Battery Cable
Signs of a bad cable:
- Corroded terminals
- Power loss from wiggling cables
- Frayed wiring
The Fix: Scrub 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 Lanos 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 completely empty 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 lights and electronics come on, the most likely culprits are issues with the starter system, ignition switch, or neutral safety switch. Defective 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 turning the key, the problem is often a bad starter motor or related wiring problem. This prevents the starter from engaging to turn the engine over for starting.
What would make my Chevy car unexpectedly not start?
Sudden no-start issues can occur from loose 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 culprit may be a bad 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 symptoms your Chevy starter is bad?
Signs of a bad starter include no noise when turning the key, a single click but no cranking, unusual grinding sounds, and slow/labored 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 is good?
If the battery and alternator check out, common causes are bad spark plugs, blocked fuel filter, blown fuse, immobilizer issue, and starter relay failure. Complete testing of all electrical and fuel systems is needed by a qualified local mechanic.
