This issue occurs due to a malfunction in the ignition start module. Below is an introduction to the car ignition system: Function: The ignition system's role is to connect or disconnect the primary circuit of the ignition system based on the ignition signal input from the signal generator, thereby generating high-voltage ignition current in the secondary winding of the ignition coil. Currently, the internal circuit designs of ignition systems in cars vary, but their basic functions are largely similar, consisting of corresponding functional circuits. Components: The ignition system mainly consists of the power source, ignition coil, distributor, ignition switch, spark plug, additional resistor and its short-circuiting device, as well as high and low voltage wires.

What are the reasons for the high fuel consumption of the 12th-generation Crown?

The reasons for the high fuel consumption of the 12th-generation Crown are as follows: Affected by temperature: This leads to fluctuations in fuel consumption. In winter, when temperatures are low, fuel consumption tends to increase. Vehicle not maintained for a long time: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil causes poor lubrication, increasing resistance in the engine's moving parts, requiring more energy to overcome the resistance, thus raising fuel consumption. Insufficient tire pressure: Low tire pressure increases the contact area between the tires and the ground, increasing friction and thus driving resistance, which leads to higher fuel consumption. Excessive carbon buildup in the vehicle: Carbon buildup can occur in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can lead to incomplete combustion, resulting in increased fuel consumption.

What are the reasons why a Camry suddenly won't start?

Here are the reasons why a Toyota Camry won't start: Fuel system issues: Severe carbon buildup in the engine can affect normal vehicle starting, and may also cause shaking during idling. This can be alleviated by cleaning the throttle body or intake pipes. Electrical system issues: Spark plug failure. Spark plugs work through high-voltage discharge. When the ignition coil sends pulsed high voltage to the spark plug electrodes, the high voltage breaks down the air-fuel mixture to create a spark, allowing the engine to start normally. Spark plugs are one of the most important components in a vehicle. Mechanical issues: Insufficient cylinder compression pressure. This can be caused by: leakage between the cylinder head and cylinder block; leakage between the spark plug gasket and cylinder head or faulty decompression valve; crankcase leakage; or leakage due to severe wear between piston rings and cylinder walls or stuck piston rings.
