Fuel not getting through, no power, engine warning light is on. What's the situation? Is it the fuel injector or the catalytic converter?

The check engine light is on for your 2010 Mazda3 hatchback, and the fault code indicates that the fuel trim system is too lean after the catalytic converter. Here's what you can do: 1. **Check for Vacuum Leaks**: Inspect hoses and connections for any leaks that might be causing the issue. 2. **Inspect the Oxygen Sensors**: A faulty oxygen sensor can lead to incorrect fuel mixture readings and should be checked. 3. **Examine the MAF Sensor**: The Mass Air Flow sensor might be dirty or malfunctioning, affecting the air-fuel ratio. 4. **Look at the Fuel System**: Check the fuel injectors and fuel pressure to ensure they are functioning properly. 5. **Check the Catalytic Converter**: Although less common, a failing catalytic converter can cause similar issues. 6. **Professional Diagnosis**: If you're unable to identify the problem, it may be best to consult a professional mechanic for a thorough diagnosis. Remember, addressing the issue promptly can prevent further engine damage.

For the 2011 Suzuki Liana, if you're getting a catalytic converter fault warning, there are a few things you can consider. First, you might want to confirm the diagnosis with another mechanic to ensure it's indeed the catalytic converter that's the issue. Sometimes, other components like oxygen sensors can also trigger similar warnings. If replacing the catalytic converter is necessary and the cost quoted is over two thousand, you might want to compare prices from different repair shops or consider aftermarket parts, which can sometimes be more affordable.
