Why does the Teana not start and the brake pedal feels hard?
4 Answers
The Teana fails to start and the brake pedal feels hard because the vacuum booster pump is required to assist when pressing the brake. If the vacuum booster pump lacks assistance, the brake will have no power assist, making it difficult to press down. For the vacuum booster pump to generate assistance, the car's engine must be running so that the pump can create a vacuum. Engine carbon buildup: This failure to start is mainly caused by excessive carbon buildup in the idle speed motor, intake tract, intake valves, and combustion chamber. Excessive carbon deposits and dirt in the intake tract alter the cross-sectional area of the air passage, leading to an overly rich or lean air-fuel mixture. This results in abnormal combustion, engine shaking after starting, or even a complete failure to start. Fuel injector leakage: The Zotye T600's failure to start may also be due to issues with the fuel injectors, such as leakage or excessive carbon buildup, causing a lean air-fuel mixture during startup and making it difficult to start. Additionally, when the carbon canister or carbon canister solenoid valve malfunctions, it can also lead to difficulty in starting.
My previous Teana also experienced this situation. When the ignition had no response at all, the brake pedal was particularly hard to press. At first, I thought something was broken and was quite worried. Later, I figured out that it was mainly because the engine wasn't running, so it couldn't supply air to the brake vacuum booster, making the brake pedal unusually hard—this is actually a normal phenomenon. Common reasons for no ignition response are mostly battery-related issues, such as an old or dead battery, or loose battery terminals causing poor contact. The starter motor won't receive the signal and thus won't work. I'd suggest you first check if the interior lights turn on. If they don't, it's almost certainly a battery problem. In that case, avoid repeatedly attempting to start the car to prevent the battery from dying completely. If the battery is dead, you can either jump-start the car or push-start it as an emergency measure, but be careful with push-starting to avoid damaging parts. Regularly checking the battery's condition and keeping the terminals clean can help prevent such issues—safety first, after all.
I've been driving my Teana for several years, and it's a bit annoying every winter when I find the car won't start in the morning and the brakes are unusually stiff. This is mostly a linkage issue - if the engine doesn't start, the brake booster fails because the vacuum booster relies on engine suction. The starting problem could be due to a weak battery, especially in cold weather when old batteries struggle more, or it might be a broken starter connection or blown fuse. For troubleshooting, start with the basics: check if the key is properly inserted and whether the dashboard lights come on. If the lights are on, it's likely an engine issue; if not, the problem is definitely the battery. I suggest getting a friend's car to jump-start yours instead of tinkering randomly to avoid damaging the wiring. For long-term prevention, take monthly highway drives to charge the battery or replace it to avoid unexpected issues.
I'm used to driving Nissan cars and this kind of issue. When the Teana won't start and the brakes feel stiff, it's usually because the engine isn't running and the vacuum pump isn't working. The most likely causes are insufficient battery power or poor contact in the starting circuit. Sometimes there's also a bug with the ignition switch. A simple way to check is to see if the headlights or AC fan are working properly to determine if it's a power issue. If the battery is confirmed dead, call roadside assistance for a tow or battery replacement—don't mess around, safety comes first.
