Why does the Sagitar not start when the battery has power?

[DelSienna]

The reasons why the Sagitar does not start when the battery has power are: 1. Damaged spark plugs: Damaged spark plugs in the engine are one of the reasons why the car cannot start, as spark plugs are necessary to ignite the gasoline in the cylinders and make the engine run; 2. Distributor circuit failure: The main circuit for starting is the distributor, and if the distributor is damaged, it may also cause failure to start; 3. Starter damage: The starter is responsible for driving the engine during ignition, and if the starter is damaged, the car cannot start. The Sagitar is a spacious A+ class comfortable sedan that perfectly combines German craftsmanship with modern and dynamic styling. In terms of body dimensions, the Sagitar measures 4544mm in length, 1760mm in width, and 1461mm in height.

My Sagitar also had this issue before, the battery was full but nothing happened when turning the key. After checking for a long time, it turned out to be a starter problem—either the carbon brushes were worn or the magnetic switch was faulty. Another possibility is poor contact in the ignition switch, requiring multiple turns to get power. Also, check the starter circuit fuse in the fuse box; if it's blown, it can cause the car to have power but fail to start. A loose ground wire is another common issue—remember to tighten the battery negative terminal with a wrench. By the way, have you modified the circuit recently? Incorrect wiring from installing accessories like dash cams can also interfere with the start signal.

Buddy, I've encountered this symptom before when I was into car modifications. The battery voltage checks out fine, but the starter shows no response at all. Focus on three key areas: First, the starter relay—find a same-model replacement in the engine compartment fuse box for testing. Second, the gear position sensor—automatic transmission cars won't start if the P-gear contact is faulty. Third, the brake switch—if this is broken, even pressing the brake won't unlock an automatic transmission. There's also a small chance the key chip signal is lost, so try using the spare key. When testing, get an assistant to listen for the 'click' sound of the relay engaging during startup.

I was in a hurry to take my child to school in the morning. When I turned the key, the dashboard lit up but the engine didn't respond at all. The battery was newly replaced, so it definitely had power. Later, the mechanic taught me to check the brake lights, and it turned out the taillights didn't illuminate when pressing the brake. It was a faulty brake switch. Automatic transmission cars require pressing the brake to start, and this switch is located above the brake pedal—you can feel it by bending down. Another time, the steering wheel lock was stuck, and I solved it by turning the steering wheel left and right while turning the key. Now I've learned my lesson: when this happens, first check if the gearshift lever is properly in the P position.

Buddy, you gotta trace the circuit for this fault! If the battery has power, it means the supply is OK, and the issue lies in the control circuit. First, use a multimeter to check the starter's 50-terminal. If there's no 12V when turning the key, it's an upstream problem. Check if the wiring from the ignition switch to the starter relay is intact—the relay coil needs power to engage. For automatic transmissions, don't forget to inspect the series circuit of the gear position switch and brake light switch. Cars with aftermarket push-start systems are especially prone to issues—faulty control modules can randomly block the start signal. False alarms from the anti-theft system locking up are another common cause.

I'd say focus on the starter! Have the battery terminals been cleaned? Oxidation can cause weak power. Gently tap the starter casing with a hammer—sometimes dislodging stuck carbon brushes can get it going. Check the voltage at the starter solenoid; no voltage means a fuse or wiring issue, while voltage without action indicates a faulty solenoid. Also, check the clutch pedal switch (for manual transmissions)—if not fully depressed, it won't start. Keep an OBD scanner handy to read fault codes; electronic throttle initialization errors can also lock the engine.
