What are the reasons why a Mondeo has power but cannot start?

[DeReid]

Mondeo has power but cannot start may be due to a faulty fuse in the fuse box, starter motor failure, ignition switch failure, etc. The following is a detailed introduction to the situation where the Mondeo cannot ignite: 1. Overview: Generally speaking, open circuits, short circuits, and damage to electrical equipment are common problems in the circuit system. Among them, aging circuit wiring and excessive load on the car circuit are the reasons. Because when the engine is working, the temperature of the ignition coil is very high, which can easily soften, age, and crack the insulation layer of the high-voltage ignition wire. The high-voltage ignition electricity can easily break down the insulation layer, causing high-voltage electricity leakage and short circuits. 2. Others: Modern cars have more and more electronic control technologies, and the application of car intelligence has greatly increased the corresponding power consumption of car electronics. The load space of the car's circuit system is limited, and the car's microcomputer, electronic components, and various sensor circuit systems are easily damaged. Adding various additional electronic equipment to the car in large quantities may also increase the burden on the car's circuit.
