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 immobilized and uncertain about the cause. Luckily, some common problems lead to Chevy Agile not starting, many of which can be fixed DIY or quickly by a mechanic.
In this comprehensive guide, we're going to look at the top 14 reasons your Chevy Agile doesn't start and provide helpful suggestions to get your car started again.
Drained or Dead Battery
The most common reason a Chevy won't start is a dead or drained battery. Your battery supplies the initial jolt of electricity to crank the engine and get it running.
Indications of a dead battery:
- Silence upon turning the key – no engine cranking
- Accessories not powering on
- Difficulty starting in cold weather
How to Fix It: Keep jumper cables available in case of a dead battery situation. Jump starting your Chevy Agile using another vehicle 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 persist, have your battery tested – it may need recharging if old.
If your battery checks out but your Chevy Agile still won't turn over, the culprit may be a bad alternator. This key component charges your battery when running and energizes the electrical system.
Signs of a bad alternator:
- Battery warning indicator illuminating
- Electronics fading
- Difficulty starting, especially after short trips
The Fix: Get your alternator inspected ASAP 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 ignite the air/fuel ratio in the cylinders to power your car. When they are fouled or worn out, your Agile may not start due to no spark.
Signs of bad spark plugs:
- Poor fuel economy
- Rough idle
- Engine misfiring
The Fix: Spark plugs need regular replacement as they degrade. Most last 30k+ miles. Have your plugs checked and swap any faulty ones. Using quality gas prevents buildup.
Ignition System Issues
Problems with ignition components like the switch, lock cylinder, fob, or wiring can prevent your Chevrolet from cranking.
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 Chevy Agile may not turn over.
Signs 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.
Not in Park or Neutral
If your transmission isn't in Park or Neutral, your Chevrolet's safety features will prevent it from starting.
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.
Clogged Fuel Filter
A clogged fuel filter can restrict fuel delivery to the engine, preventing your Chevrolet Agile from turning over.
Signs of a clogged filter:
- Hard time starting
- Engine sputtering
- Decreased fuel economy
The Fix: Replace the filter per your schedule or if suspected 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.
Bad or Failing Fuel Pump
The fuel pump draws gas from the tank to the engine. If it fails, your Chevy won't start due to no fuel.
Signs of a bad pump:
- No pump noise upon turning key
- Hard time starting
- Stalling when running
The Fix: Have your pump tested. If faulty, a mechanic near you will need to replace it.
Low Engine Compression
Proper compression is required to combust the air/fuel mixture. Low compression from damage can lead to a no start.
Symptoms of compression issues:
- Hard time 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.
Broken Timing Belt
The timing belt synchronizes the camshaft and crankshaft. If it breaks, the valves and pistons aren't synchronized properly and your Chevy Agile won't start.
Symptoms of a bad timing belt:
- No start
- Unusual clicking sound
The Fix: Have your belt inspected and fixed right away if broken. This requires a local professional mechanic to replace the timing belt of your Chevy Agile.
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 Agile from starting or running right.
Diagnosing 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.
Low Fuel or Empty 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 flush 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 causes 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 doesn't crank?
When your Chevy has power to the lights and accessories but doesn't start when trying to start, the problem is often a bad starter motor or related wiring problem. 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 problems 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 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 upon turning the key, a single click but no turnover, unusual grinding noises, 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 is good?
If the battery and alternator check out, common causes are bad spark plugs, clogged fuel filter, blown fuse, immobilizer problem, and starter relay failure. Complete testing of all electrical and fuel systems are needed by a qualified local mechanic.
