What is the reason why the Vios has electricity and oil but cannot start?
2 Answers
Vios has electricity and oil but cannot start because the gear is not adjusted properly. For automatic transmission cars, the gear must be placed in P or N gear. If it is placed in R or D gear, it will not start and will also bring certain safety hazards. Nowadays, most cars have corresponding gear shift reminders, so the probability of this happening is relatively small. For emergency solutions, the following specific instructions are provided: 1. Gear: Place the gear in P or N gear. 2. Steering wheel lock: Some friends may find that the key cannot be turned when starting the car. At this time, it is important to check if the steering wheel is locked. This is an anti-theft measure. If it is locked, the key cannot be turned and the car cannot start. When the steering wheel is shaken back and forth and the key is turned, it can be unlocked quickly. 3. Fuel filter blockage: Different degrees of blockage in the fuel filter can cause insufficient fuel supply to the engine, leading to excessive fuel system pressure, making the car unable to start. There may also be jerking situations during driving.
I have a mechanic friend who often deals with this issue. The Vios has power and fuel but won't start, which is commonly caused by ignition system failures, such as worn-out spark plugs that can't produce sparks or faulty ignition coils that fail to ignite the air-fuel mixture. Additionally, the fuel pump might be problematic—there's fuel in the tank, but the pump is broken and can't deliver it, or the filter is clogged, leading to poor fuel supply. Sensors are another major issue; if the crankshaft position sensor fails, the ECU won't receive a signal and prevent startup. Last month, my own Vios had the same problem, and it turned out the anti-theft system had locked the engine, requiring a key reprogram. I recommend regular maintenance of spark plugs and the fuel system, and don't neglect periodic checks—address issues early at a repair shop to avoid being stranded on the roadside. If the weather is cold, even with sufficient battery voltage, insufficient cranking power could also be a contributing factor.
