The situation when the crossover Lifan X60 Refusing to launch, always catches the owner by surprise, disrupting plans and causing legitimate irritation. This popular in the budget segment of the car, despite the overall reliability, has a number of specific “sicknesses” that can lead to engine failure. Most often, the problem lies in the power or ignition system, but sometimes more complex electronic components are also the culprits.
Before panicking or calling a tow truck, primary visual and auditory diagnosis is necessary. The nature of the sounds when turning the key in the ignition lock can tell a lot to an experienced mechanic or an attentive driver. If the starter is silent or makes strange clicks, the circle of suspects narrows to a battery pack and a retractable relay. If the motor turns cheerfully, but "snatching" does not occur, you need to look for a malfunction deeper.
Owners of Chinese crossovers should be especially attentive to the quality of fuel and the state of electrical contacts. Oxidation terminals Filter clogging is a frequent satellite of operation in the Russian climate. Understanding the basic principles of the start-up system will help you save time and money by eliminating the fault yourself or correctly formulating the task for the service technicians.
Diagnostics of the battery and starter
The most common, but common, reason why Lifan X60 It doesn't start, it's in a discharged battery. In winter or after prolonged downtime, the battery capacity may drop to the critical values needed to scroll the crankshaft. If you hear only frequent cracking or single clicks when you turn the key, and the lights on the dashboard dim, then there is not enough energy.
However, it can be not only in charge, but also in poor contact. The terminals are often oxidized, covered with a white coating, which prevents the passage of high-force current. Poor mass contact It can also cause a voltage drop in the onboard network. Check the tension of the generator belts, as slipping it may have prevented the battery from charging fully during the previous trip.
⚠️ Attention! If you use the lighting method from another car, strictly observe the polarity of the wire connection. Error in connecting the “plus” and “minus” will instantly disable engine control unit (ECU) They turn a small problem into an expensive repair.
If the battery is charged, the terminals are clean, but the starter does not spin at all, perhaps the device itself is faulty. The retractable relay could stick or burn. Sometimes it helps to gently tap the starter body with a hammer handle (subject to safety precautions), which allows you to temporarily return mobility to the brushes or anchor to reach the service.
Problems with the ignition system and candles
When the starter is working properly and the crankshaft rotates at a normal frequency, but the engine does not start, it is worth checking the spark formation system. V Lifan X60 individual ignition coils are installed on each cylinder, which increases reliability, but complicates diagnosis. Coil failure or the ignition module causes the fuel in the cylinders to not ignite.
Spark plugs are consumable material that requires regular replacement. If they are filled with gasoline (often after repeated failed launch attempts) or covered with carbon, the spark either does not slip or has insufficient power. Visual inspection of candles can tell about the state of the engine: black soda will indicate a rich mixture, and white - overheating or poor mixture.
It is also worth paying attention to high-voltage wires, if they are present in your modification, or the state of the coil connectors. Oxidized contacts or cracks in the insulation lead to a leakage of current. In wet weather or after engine washing, moisture can get into candle wells, causing a "breakout" on the mass.
☑️ Checking of the ignition system
For accurate diagnosis, special equipment is often required that will show ignition gaps in a particular cylinder. If the problem lies in the sensor position of the crankshaft, then there will be no sparks in any cylinder, since the ECU will not know at what time to give a signal for ignition.
Failure of the fuel system
Lack of fuel in the ramp is the second most common cause of engine failure. If the starter spins cheerfully, there is a spark, but the car does not start, most likely does not work. fuel-pump. When you turn on the ignition, before the starter starts, you should hear a characteristic buzzing from the back seat area or the trunk where the fuel module is located.
If there is no sound of the pump, check the fuse and relay of the gas pump. They can burn out due to a surge in tension or old age. Also often fails the motor of the pump itself or its electrical part. In winter, condensate may freeze in the fuel line or form an ice plug in the filter.
| Symptoms. | Probable cause | Action. |
|---|---|---|
| The pump is not humming | Fire-fuse or relay. | Replace the fuse/relay |
| Good, but not rocking. | Clogged filter or pump | Replace the fuel filter |
| Pressure's low on the ramp. | Pressure regulator or pump | Measure with a gauge |
| Black smoke from the exhaust | Nozzle overflow | Check the pressure regulator |
Another problem may be the contamination of fuel nozzles. If the car has long been operated on low-quality gasoline, the nozzle sprayer can coke, breaking the spray torch. In this case, the fuel does not burn completely, and the engine does not start.
How to check the pressure in the fuel ramp?
You will need a manometer with an adapter to check. Connect it to a fitting on the fuel ramp (preliminarily putting pressure through the valve, if any, or gently unscrewing the hose). Turn on the ignition. The pressure should be about 3.8-4.0 atmospheres and hold after the pump is turned off. If the pressure drops instantly, the regulator or the pump return valve is defective.
Sensors and Electronics: The Role of EBUs
Modern. Lifan X60 It is controlled by a complex electronic unit that collects data from multiple sensors. If crankshaft position sensor (CRP) transmitting an incorrect signal or not transmitting it at all, the ECU “does not know” that it needs to give a spark and fuel. This is one of the most common electronic reasons for a launch failure.
It is also worth mentioning the throttle position sensor and the idle regulator. If they fail, the engine may stall immediately after starting or not start at all if the valve is closed completely or, conversely, jammed in the open position. Electronic errors are often recorded in the memory of the ECU.
Diagnostics using the OBD-II scanner allows you to read error codes that indicate a specific faulty node. However, not always the presence of an error means that the detail needs to be changed. Sometimes the problem lies in a wiring break or poor contact in the connector, which is characteristic of the vibration loads experienced by the car.
⚠️ Attention! Resetting errors by removing the battery terminal does not always solve the problem. If the physical sensor is faulty, the error will reappear after the first launch cycle. Ignoring the “Check Engine” signals can lead to increased fuel consumption and failure of the catalyst.
Mechanical problems of the engine
If all the systems are working properly, but Lifan X60 It doesn’t work, maybe it’s the mechanical part. The break of the belt of the GRM is the worst dream of the owner. In this case, the camshafts stop rotating, the valves do not open, and the engine will not start. Unfortunately, many Lifan engines when the belt breaks, the pistons meet the valves, which requires major repairs.
Low compression in the cylinders will also prevent the engine from starting. Wear of piston rings, burn valves or breakdown of the gasket of the HBC lead to the fact that the cylinders do not create the necessary pressure to ignite the mixture. You can check the compression using a compressometer screwed into the candle hole.
Another rare but possible cause is engine jamming due to oil starvation or overheating. In this case, the starter will not be able to turn the crankshaft, and you will hear a heavy hum or click with the subsequent stop of rotation.
Checking the belt of the HRM on the Lifan X60 requires the removal of the protective casing. Visually assess the condition of the belt teeth. If cracks, stratifications or lack of teeth are noticeable, it is impossible to operate the car, an immediate replacement of the HRM kit is required.
Impact of climate conditions and seasonal problems
The winter engine start is stressful for any car. Lifan X60 No exception. Thick motor oil increases the resistance to rotation, and the cold battery loses some capacity. If the car does not start in the cold, try to pre-heat the battery, turning on the high beam headlights for a few seconds, and then turning it off before trying to start.
In wet weather or after washing, moisture can get into the ignition distributor (if any) or on high-voltage elements. In such cases, the treatment of contacts with moisture-protective sprays helps. In summer, the main problem may be overheating of the gas pump or the formation of steam stoppers in the fuel system.
Fuel quality also plays a critical role. Low-octane gasoline or the presence of water in the tank can cause detonation or a complete absence of ignition. In such cases, it is recommended to drain the suspicious fuel and add quality gasoline with an octane number recommended by the manufacturer to the tank.
Seasonality affects the choice of motor oil. For winter, use synthetic oils with low freezing temperatures (such as 5W-30 or 0W-20) to ease cold start-up and reduce the starter and battery load.
Frequently Asked Questions (FAQ)
Why does the Lifan X60 start and go down?
Most often, this indicates a malfunction of the idle regulator, a sucking of unaccounted air in the intake ring or a problem with the throttle position sensor. It is also worth checking the pressure in the fuel ramp – if it drops immediately after starting, the pump or pressure regulator does not keep the desired parameters.
What if the starter clicks but doesn’t spin?
First, check the battery charge and the purity of the terminals. If they're all right, they probably wore the starter brushes or burned the retracting relay's five-footers. In an emergency, you can try to gently tap the starter's body, but it is better to replace the faulty node.
Can the alarm block the engine from starting?
Yes, if an additional security system with engine lock function is installed, it can prevent starting when its battery is discharged or malfunctioning. Try to switch the system to service mode or disable the lock according to the alarm instructions.
How often should I change candles to Lifan X60?
The recommended interval for replacing spark plugs is 30-40 thousand kilometers. However, when using poor-quality fuel or frequent short trips, the resource can be reduced. Visual inspection and clearance check will help determine the need for replacement.
