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 fails to start will leave you stranded and clueless about the issue. The good news is that a number of familiar culprits make a Corvairs 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 top 14 causes your Chevy Corvair won't start and offer helpful suggestions to get your car running again.
Drained or Dead Battery
The most common reason a Chevy won't start is a dead or weak 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 for a dead battery emergency. Jump starting your Chevrolet Corvair using another vehicle or jump box can supply enough juice to get it started.
You can also clean corroded battery terminals that are blocking a good connection. If problems persist, have your battery tested – it may need replacing if worn out.
If your battery checks out but your Chevrolet Corvair still won't turn over, the culprit may be a bad alternator. This key component charges your battery while driving and powers the electronics.
Clues of a bad alternator:
- Battery warning indicator illuminating
- Lights fading
- Hard time starting, particularly following short trips
The Fix: Get your alternator checked ASAP by a mechanic. A bad alternator can quickly drain your battery. This will need to be replaced by an experienced mechanic.
Bad or Fouled Spark Plugs
Spark plugs fire the fuel/air mixture in the cylinders to run your car. When they are dirty, bad, or corroded, your Corvair may not start due to no spark.
Clues of bad spark plugs:
- Poor fuel economy
- Rough idle
- Engine hesitating
The Fix: Spark plugs need periodic replacement as they degrade. Most last 30k+ miles. Have your plugs inspected and change any faulty ones. Using quality gas helps avoid buildup.
Problems with ignition components like the switch, lock cylinder, fob, or wiring can prevent your Chevy from cranking.
Signs of ignition trouble:
- No noise upon turning key
- Instrument panel malfunctioning
- Key won't turn
The Fix: For fob issues, replace 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 Chevrolet Corvair may not crank.
Signs of a bad starter:
- No noise upon turning key
- Clicking but no turnover
- 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 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 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 Chevy Corvair from starting.
Symptoms of a clogged filter:
- Hard time starting
- Engine sputtering
- Decreased fuel economy
The Fix: Replace the filter when due or if suspected 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 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 leaks can cause a no start.
Signs 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.
Timing Belt Failure
The timing belt keeps the camshaft and crankshaft. If it breaks, the valves and pistons won't be timed properly and your Chevrolet Corvair won't start.
Signs of a bad timing belt:
- No start
- Unusual clicking sound
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 Corvair.
Detached or Loose Battery Cable
Symptoms 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 Corvair 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.
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 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 come on, the most likely culprits are issues with the starter system, 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 doesn't crank?
When your Chevy has power to the lights and accessories but doesn't start when turning the key, 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 cause 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 critical problems can arise without warning and prevent your Chevy's engine from starting.
Why doesn'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 flow problem 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 upon turning the key, a single click but no cranking, unusual grinding noises, 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 are good?
If the battery and alternator check out, common culprits 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.
