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 immobilized and uncertain about the cause. The good news is that a number of familiar culprits make a Rezzos fail to start, and you can fix a lot of them yourself or with a mechanic's assistance.
In this comprehensive guide, we'll explore the fourteen most common causes your Chevrolet Rezzo won't start and offer helpful suggestions to get your car running again.
The most common cause a Chevy won't start is a dead or drained battery. Your battery provides the initial burst of electricity to turn over the engine and get it started.
Indications of a dead battery:
- Silence upon turning the key – no engine cranking
- Electronics not powering on
- Difficulty starting in cold weather
The Fix: Keep jumper cables on hand for a dead battery situation. Jump starting your Chevrolet Rezzo using another vehicle or jump box can deliver enough juice to get it started.
You can also clean dirty battery terminals that are blocking a good connection. If problems persist, have your battery tested – it may need replacing if old.
If your battery checks out but your Chevrolet Rezzo still won't turn over, the issue may be a bad alternator. This key component charges your battery while driving and energizes the electrical system.
Clues of a bad alternator:
- Battery warning light coming on
- Lights dimming
- Difficulty 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 fire the air/fuel ratio in the cylinders to run your car. When they are dirty, bad, or corroded, your Rezzo may not start due to no spark.
Clues of bad spark plugs:
- Poor fuel economy
- Rough idle
- Engine sputtering
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.
Ignition System Issues
Problems with parts like the switch, lock cylinder, fob, or wiring can prevent your Chevy from cranking.
Signs of ignition trouble:
- No noise upon turning key
- Dashboard 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 crank the engine. If it's worn out, your Chevy Rezzo may not crank.
Signs of a bad starter:
- No noise upon turning key
- Clicking but no turnover
- Unusual noises
The Fix: Have your starter tested 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 cranking.
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.
Clogged Fuel Filter
A blocked fuel filter can constrain fuel flow to the engine, preventing your Chevy Rezzo 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 replace 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.
Symptoms of a bad pump:
- No sound upon turning key
- Hard time 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 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.
Broken Timing Belt
The timing belt synchronizes the camshaft and crankshaft. If it snaps, the valves and pistons won't be timed properly and your Chevrolet Rezzo won't start.
Signs of a bad timing belt:
- No start
- Unusual clicking sound
The Fix: Have your belt inspected and replaced immediately if broken. This requires a local professional mechanic to replace the timing belt of your Chevy Rezzo.
Loose or Detached 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 Rezzo 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 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 starting but I have power?
If your Chevrolet won't start but the lights and electronics come on, the most likely causes are issues with the starter motor, ignition switch, or neutral safety switch. Faulty ignition components prevent the engine from turning over even when battery power is present.
Why does my Chevy have power but won't turn over?
When your Chevy has power to the electronics and dashboard 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 make my Chevy car suddenly 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 delivery 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 sounds, and difficult 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 are good?
If the battery and alternator check out, common culprits are bad spark plugs, clogged fuel filter, blown fuse, immobilizer issue, and starter relay failure. Thorough testing of all electrical and fuel systems are needed by a qualified local mechanic.
