Sitting in your idle Chevy, turning the key, and hearing nothing but silence can be very aggravating. A Chevy that fails to start leaves you immobilized and uncertain about the cause. Luckily, some common problems lead to Chevrolet Kadett 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 causes your Chevy Kadett won't start and offer useful tips to get your car running again.
The most common cause a Chevy won't start is a dead or drained battery. Your battery delivers the initial jolt of electricity to turn over the engine and get it started.
Indications of a dead battery:
- Silence upon turning the key – no engine cranking
- Accessories not powering on
- Hard time starting in cold weather
The Fix: Keep jumper cables available in case of a dead battery emergency. Jump starting your Chevy Kadett using a good battery or portable charger can supply enough charge to get it cranked.
You can also try cleaning dirty battery terminals that are blocking a good connection. If problems continue, have your battery tested – it may need recharging if worn out.
If your battery tests fine but your Chevrolet Kadett still won't turn over, the culprit may be a bad alternator. This vital part charges your battery while driving and energizes the electrical system.
Signs of a bad alternator:
- Battery warning light coming on
- Lights fading
- Difficulty starting, particularly following short trips
The Fix: Get your alternator checked right away by a mechanic. A bad alternator can quickly drain your battery. This will need to be replaced by an experienced mechanic.
Faulty Spark Plugs
Spark plugs fire the fuel/air mixture in the cylinders to run your car. When they are dirty, bad, or corroded, your Kadett may not start due to no spark.
Signs 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 prevents buildup.
Ignition System Issues
Issues 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 flickering
- Key won't turn
The Fix: For fob issues, try the battery. For other problems, have the system diagnosed 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 worn out, your Chevy Kadett may not turn over.
Symptoms of a bad starter:
- No noise upon turning key
- Clicking but no cranking
- Unusual grinding or whining
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 Chevy's safety features will prevent it from starting.
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.
Blocked or Clogged Fuel Filter
A clogged fuel filter can constrain fuel flow to the engine, preventing your Chevy Kadett from starting.
Symptoms of a clogged filter:
- Difficulty starting
- Engine misfiring
- Decreased fuel economy
The Fix: Replace 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 draws 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 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 worn parts can cause 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.
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 Chevy Kadett won't start.
Signs of a bad timing belt:
- No start
- Unusual ticking noise
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 Kadett.
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 Kadett 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 clear the system so the plugs can spark. If problems continue, have the carburetor adjusted by a professional local mechanic.
