What are the reasons for a car having a little electricity but not starting?
2 Answers
Car having a little electricity but not starting reasons are as follows: Is the battery charged: It may be due to power loss caused by reasons such as leaving the headlights on for a long time or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, DVD players, etc., can also cause vehicle circuit failures. Checking for no power in the vehicle is simple; just press the horn. Is there fuel: Pay attention to the quality of the fuel. Always refuel at reputable gas stations. When traveling, you can use a gauze to cover the fuel gun nozzle to filter out impurities. Wrong gear position: For automatic transmission cars, the gear must be in P (Park) or N (Neutral) when starting. If it is in R (Reverse) or D (Drive), the car will not start. Electronic failure: Mainly refers to the central computer control board losing functionality. Mechanical failure: Timing belt (chain) breakage, cylinder leakage causing no pressure, etc.
A few days ago, my car had the same issue—dashboard lights on but the engine wouldn't start. After checking, I found the battery voltage had dropped below 10V. Although the small lights still worked, the starter couldn’t turn over. This is a common problem with older car batteries, especially in winter when low temperatures reduce battery capacity. I’ve also encountered a situation where the starter relay contacts were burnt, causing a clicking sound but no action. Remember to check if the battery terminals are oxidized or covered in white residue—last time, mine had green corrosion causing poor contact. If all else fails, try jump-starting the car. If that doesn’t work, you might need to replace the starter or check the fuel pump fuse.
