Why Won't the Prado Start?

[SanDominic]

The Prado's failure to start can be attributed to improper fuel quality, lack of antifreeze, or excessive carbon buildup. Beyond human operational errors, potential causes include motor failure, fuel pump supply issues, injector problems, or sensor malfunctions. These complex situations require professional attention. Regular attention to the following aspects can help avoid such complications. Fuel Quality Issues: During repairs, tanks have been found containing water and mud—using such fuel inevitably damages the vehicle. Always refuel at reputable gas stations; when traveling, use a gauze over the pump nozzle to filter impurities. Lack of Antifreeze: Some owners use water or substandard antifreeze, leading to frozen coolant systems in extreme cold, cracked engines, inoperative water pumps, starting failures, and damage to other engine components. Excessive Carbon Buildup: This can prevent the vehicle from starting. Regular highway driving helps reduce carbon deposits. Additionally, a starting tip: before ignition, turn the key to the ON position, pause, then switch to START, allowing the ECU to calculate optimal water temperature and air intake for smoother ignition.
