If the starter Mitsubishi Lancer 9 rotates the crankshaft at a normal speed, but the engine does not grasp, the problem most often lies in the absence of a spark or insufficient fuel pressure. Owners of the ninth Lancers, equipped with reliable engines 1.3, 1.6 and 2.0, often face a situation when after turning the key, the machine simply remains silent or emits only clicks. This may indicate a discharged battery, oxidized terminals, or a starter failure. It is important to immediately determine the nature of the sound: a sluggish click of the traction relay or a complete lack of reaction of the onboard network.
No launch motor when rotating starter requires immediate check of the ignition system and fuel supply. In the cold season, the situation is aggravated by condensation in the tank or frozen candles. If the car stopped starting suddenly after passing a puddle, it is worth checking the condition of high-voltage wires and coils for breakdown. Ignoring primary symptoms, such as tripling or difficulty starting, often leads to more complex and costly repairs to nodes. engine-control.
Problems with the start-up system and battery
The most common, but common, reason why Lancer 9 It does not start, it is in a discharged battery. In winter, the battery capacity drops, and even a serviceable starter can not turn the crankshaft with the required frequency. If the indicators on the dashboard are turned off when the key is turned or a crack is heard, it is necessary to check the voltage at the terminals. Normal value is considered not lower than 12 volts at rest, and under load it should not fall below 9-10 volts.
Often the problem lies not in the battery itself, but in poor contact. The terminals are oxidized, covered with white coating, which creates a high resistance. Even if the starter is spinning but sluggish, the engine may not start due to lack of power to create a spark. It is necessary to carefully clean the contacts and check the reliability of the mass attachment on the body and engine. Weak mass contact is a typical βdiseaseβ of Japanese cars that causes chaotic electronic failures.
The failure of the starter itself cannot be excluded. Wear of the retracting relay, brush or bushing leads to the fact that the bendix does not get engaged with the flywheel or the anchor does not rotate. In such cases, a characteristic metallic clang or single click is often heard. Starter repairs usually require removal of the knot and defects, although sometimes light tapping on the body in an emergency helps.
- π Check the battery voltage with a multimeter and charge it if necessary.
- βοΈ Clean the battery terminals and check the attachment of the mass wire to the engine.
- π§ Listen to the starterβs work: is he rotating the crankshaft at the right speed?
- π‘ Make sure the indicators on the dashboard donβt go out when you try to start.
β οΈ Warning: If the starter makes a shrill screech after starting, immediately shut off the engine. This is a sign that the bendix is not coming out of the grip, which can lead to the destruction of the flywheel crown.
Failures of the ignition system: candles and coils
When the starter turns the engine, Mitsubishi Lancer 9 It does not start, you should look for the reason in the absence of a spark. The engines of this family (4G13, 4G18, 4G63, 4G64) are equipped with individual ignition coils located directly above the candles. Failure of even one coil can lead to trinity, but if the control module does not work or the common fuse is burned, there will be no sparks in any cylinder.
The ignition plugs are the second critical element. Nagar, increased gap between electrodes or breakdown of the insulator do not allow to ignite the fuel-air mixture. This is especially true for gas equipment, where the requirements for candles are higher. If the twisted candle is wet and smells of gasoline, then the fuel is supplied, but does not burn. A dry candle indicates problems with fuel supply or compression.
Checking high-voltage wires (if they are in your modification) and coil tips is mandatory. In wet weather, microcracks in isolation cause a breakdown to the mass, and the spark goes to the side, not to the cylinder. Visually, this can be seen in the dark by the blue glow around the wires when the engine is running or when scrolling with a starter.
How to Check the Spark on Lancer 9
Unscrew the candle, put a coil tip or wire on it. Press the threaded part of the candle to the "mass" (metal part of the engine). Ask the assistant to spin the starter. A bright blue spark indicates the serviceability of the system.
Fuel system: gas pump and pressure
The lack of start-up is often caused by a banal lack of gasoline in the tank or a faulty fuel pump. Nana Lancer 9 The gas pump is located in the tank, and when you turn on the ignition, you should hear a characteristic buzzing lasting 2-3 seconds. If this sound is not present, check the fuel pump fuse and relay. A burnt fuse is a common cause of a sudden stop of the car on the move.
The pressure in the fuel ramp is a key parameter for injection engines. If the filter is clogged with dirt, the pump will not be able to pump the right amount of fuel, and the pressure to open the nozzles will not be enough. Regular replacement of the fuel filter is a mandatory procedure, especially considering the quality of the fuel at many gas stations. Clogged nozzles can also be the cause, but usually the engine before that long "troubles" and loses power.
The critical point is the serviceability of the fuel pressure regulator. If it doesn't keep the pressure in the ramp after the engine is turned off, the gasoline drains into the tank and it will take several times to start the ignition to pump the system again.- β½ Listen to the operation of the gas pump when turning on the ignition.
- π’οΈ Check the state of the fuel filter and replace it with planned maintenance.
- π Measure the pressure in the fuel ramp with a manometer (normal about 3-4 bar).
- π Check the fuel hoses for leaks and cracks.
If after a long parking Lancer 9 starts only from the second or third time, most likely, the fuel pressure regulator or the gas pump return valve is defective.
Mechanical Causes and Problems with GRM
The worst dream of the owner is a break of the belt or skipping the teeth of the belt of the gRM. On the engines. Lancer 9 when the belt breaks down, the valve bends, which requires major repairs of the cylinder head. If the starter turns the engine too easily, without the characteristic compression resistance, and the machine does not start, there is a high probability of loss of compression due to disruption of gas distribution phases.
Low compression can be caused not only by GRM, but also by piston rings or valve burnout. In this case, the engine can hoof on idle, consume oil and smoke. Checking the compression with a compressometer will give an accurate answer: if there is no pressure in the cylinders, ignition of the mixture is impossible.
It is also worth mentioning the crankshaft position sensor (PCV). This is the only sensor, if the engine does not start at all. It tells the control unit when to supply spark and fuel. Mud on the end of the sensor, damage to the wiring or magnet on the pulley of the crankshaft lead to the fact that the βbrainsβ do not see the rotation of the engine and block the start.
| Symptoms. | Probable cause | Method of verification |
|---|---|---|
| Starter's very easy to spin | GRM break, no compression. | Compression measurement, belt inspection |
| No gas pump sound. | Fire-fuse or relay. | Checking electricians in the cabin and under the hood |
| Engine's troubling and stalling. | Coil or candle failure | Turning off the cylinders |
| Check Engine caught fire | Sensor malfunction (DPKV, DMRV) | Computer diagnostics OBDII |
Impact of climate conditions on launch
Winter launch Mitsubishi Lancer 9 It can be difficult due to thickened motor oil and condensate. If the oil has not changed for a long time or its viscosity does not correspond to the season, it will be extremely difficult for the starter to turn the crankshaft. As a result, the speed to launch will be below critical, and the spark will become weak. The use of high-quality synthetic oil with low temperature characteristics (0W-20, 5W-30) facilitates cold start.
Condensation in the fuel tank is another seasonal problem. Water trapped in gasoline freezes in the fuel line or filter, blocking the fuel supply. The use of high-quality additives-dehydrators and refueling at proven gas stations minimizes risks. It is also worth checking the air filter: if it is clogged with snow or dirt, the engine will suffocate from lack of air.
Diagnostics and algorithm of fault search
To effectively find the reason why you do not start motor-carA systematic approach is needed. Don't change the details at random. Start with a visual inspection: whether the wires are intact, whether there is a smell of gasoline, whether the oil pressure bulb burns when the ignition is turned on. Then proceed to check systems in order: power, spark, fuel, compression.
Modern diagnosis is impossible without a scanner. Connecting the OBDII adapter will allow you to read error codes even if the Check Engine light bulb is not on. Errors can indicate a faulty temperature sensor, idle regulator, or throttle problems. Cleaning the throttle and idle regulator often solves problems with floating revs and difficult start-up.
βοΈ Express diagnostics in case of launch failure
In conclusion, it is worth noting that regular maintenance is the best prevention of startup problems. Timely replacement of candles, filters and belts ensures that your Lancer 9 It'll start in any weather. If self-diagnosis did not give results, do not delay with the appeal to the service to exclude serious mechanical damage.
Tip: Keep the Quick Start spray (ether) in the glove compartment for emergency start in severe frosts, but use it with caution so as not to damage the engine sensors.
Why does Lancer 9 start and go down?
Most often, this indicates a malfunction of the idle regulator, pollution of the throttle or the sucker of unaccounted air. Low pressure in the fuel ramp or problems with the immobilizer are also possible.
Could the alarm block Lancer's launch?
Yes, if you have an additional security system with engine lock. Check if the alarm light is on and try resetting or using Valet mode.
How often should I change the candles to Lancer 9?
The plant recommends replacement every 30,000 km for conventional candles and up to 60,000 km for iridium candles. However, in practice, when using quality fuel, the interval can be increased by controlling the gap and charcoal.
What if the candles on Lancer are lit?
It is necessary to twist the candles, dry them (calcinate or blow), blow the cylinders (remove the gas pedal to the floor when scrolling with the starter) and install the candles back. It is also worth checking the ignition system for weak sparks.
