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

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.
