Sitting in your idle Chevy, turning the key, and hearing nothing but silence can be very aggravating. A Chevy that fails to start will leave you stranded and clueless about the issue. Fortunately, there are several well-known issues that can cause a Tavera to not start, and you can repair many of them on your own or with a mechanic's help.
In this comprehensive guide, we will examine the top 14 reasons your Chevy Tavera doesn't start and provide helpful suggestions to get your car started again.
The most common reason a Chevrolet doesn't crank is a dead or drained battery. Your battery supplies the initial jolt of electricity to turn over 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 on hand in case of a dead battery emergency. Jump starting your Chevy Tavera using another vehicle or jump box can supply enough juice to get it started.
You can also try cleaning corroded battery terminals if they prevent a good connection. If problems continue, have your battery tested – it may need replacing if worn out.
If your battery tests fine but your Chevy Tavera still won't crank, the issue may be a bad alternator. This vital part charges your battery when running and powers the electronics.
Clues of a bad alternator:
- Battery warning light coming on
- Lights fading
- Hard time starting, particularly following 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.
Bad or Fouled Spark Plugs
Spark plugs fire the fuel/air mixture in the cylinders to power your car. When they are dirty, bad, or corroded, your Tavera may not start due to no spark.
Clues 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 inspected and swap any bad ones. Using quality gas prevents buildup.
Ignition System Issues
Issues 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
- Dashboard flickering
- Key won't turn
The Fix: For fob issues, replace 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 Tavera 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 tested 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 Chevrolet'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 constrain fuel flow to the engine, preventing your Chevy Tavera from turning over.
Symptoms of a clogged filter:
- Hard time starting
- Engine misfiring
- Decreased fuel economy
The Fix: Replace the filter when due 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.
Faulty Fuel Pump
The fuel pump delivers 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 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.
Low Engine Compression
Proper compression is required to combust the air/fuel mixture. Low compression from leaks can lead to 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 synchronizes the camshaft and crankshaft. If it snaps, the valves and pistons won't be timed properly and your Chevrolet Tavera won't start.
Signs 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 Tavera.
Loose or Detached Battery Cable
Symptoms of a bad cable:
- Corroded terminals
- Power loss from moving 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 Tavera 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 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 accessories and dashboard come 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 won't turn over?
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 system 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 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 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 noises, and slow/labored cranking. These indicate starter failure and the need for replacement by a local mechanic.
Why doesn't my Chevy car start but battery and alternator is good?
If the battery and alternator check out, common culprits 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.
