Many car owners are faced with malfunctions of the latter. Among Japanese power units, problems are rare, but what to do if the Lancer-9 does not start? Not all owners of the vehicle can determine the cause of the breakdown, and even more so on their own eliminate it.
Causes
The car stopped starting - this may be due to different systems and nodes. Immediately determine the cause is impossible. To do this, you need to carry out a number of diagnostic operations. But in this case there are a number of nodes where this reason may be hidden. Consider why the Lancer-9 may not start, and determine the main reasons.
Among them may be:
- low-quality fuel;
- problems in the fuel system;
- lack of spark, problems in ignition;
- malfunction of the air supply system to the cylinders;
- problems with electronics.
Elimination methods
As practice shows, most motorists, in order to find and eliminate the cause, go to the Mitsubishi car service. But another part of auto professionals found ways to diagnose and repair with their own hands. Of course, to accomplish this task, knowledge of the main components of the machine, appropriate tools, and also steel nerves will be required.
Petrol
Fuel quality plays a big role in starting the engine. So, regularly filling low-quality fuel, it is worthwhile to understand that at one point the power unit may not start. Clogged fuel cells will be to blame. To avoid an unpleasant situation, it is recommended to refuel the car with high-quality gasoline from trusted suppliers of petroleum products.
Spark
Most owners of the Mitsubishi engine recommend that if the engine does not start, check for a spark first. To do this, remove the armored wires and unscrew the spark plugs.
As for the elements of sparking, it is necessary to conduct a visual inspection for damage and clogging. Then you can diagnose the presence of a spark. If there is damage or no sparking, then the damaged part must be replaced.
Armored wires are checked quite easily. This will require a tester. Each wire is measured for resistance and external damage. The standard resistance of the working wire is 5 ohms.
Air supply
The air supply to the engine has two main elements - a throttle and an air filter. According to service manuals for maintenance, the filter element must be replaced every 25 thousand km. In the future, the part becomes heavily clogged, which leads to insufficient supply of air to the cylinders.
The throttle body has a tendency to clog, so it needs to be cleaned periodically. You can do this yourself using a tool for reading carburetors, or using professional tools.
Fuel line
There are three elements in the fuel system that you should pay attention to if the Lancer-9 does not start:
- fuel pump;
- fuel filter;
- nozzles.
Checking the fuel pump is simple: the ignition key is turned to position 2, and if a characteristic noise appears in the rear of the vehicle for 10 seconds, this means that the pump is operational.
But even if the gasoline pump is working, one cannot be sure that the fuel flows uninterruptedly to the nozzles and to the cylinders. There is still a filter element on the way, which can be significantly dirty. Experts recommend changing it every 40,000 km, but everything will depend on the quality of the fuel poured into the gas tank.
The last element of the fuel system, due to which the Lancer-9 does not start, is the nozzle. Often, their contamination and wear lead to an imbalance in the air-fuel mixture. So, elements can fill in too much gasoline, and very little. And precisely because of this, the Lancer-9 does not start. In this case, cleaning and diagnostics should be carried out on a special stand, which will show how efficient and suitable the parts are for operation.
Starter and battery
As in other cases, special attention should be paid to the battery, which can simply be discharged. This reason can serve as the reason that the power unit does not start. This is especially noticeable in the winter season, during severe frosts.
Starter "Lancer-9" may be another reason that the engine does not start. The main elements that at the same time fail:
In this case, the power plant may start once. Replacing parts will help solve the problem. If the winding burns out, then the Lancer-9 starter will have to be replaced, since repairs will cost more than the new assembly. It is also worth paying attention to the condition of the flywheel crown, which may have worn teeth.
ECU and errors
A common problem with the motor is errors in the engine control unit. To fix the breakdown, you need to connect to the "brain" and conduct a diagnosis. An operation is performed using special equipment. Of course, many motorists learned how to determine error codes and decrypt themselves. But it’s better to contact the official Mitsubishi auto service, where specialists using professional equipment will quickly and accurately determine what the problem is.
In 90% of cases, the cause of the malfunction is the failure of one of the sensors of the power plant, which must be replaced. The remaining 10% are related to accumulated errors inside the control unit. Elementary reset will help solve the problem. And if cleaning up the errors did not help, then it is recommended to carry out an updated firmware of the brains. If this does not help, you definitely need to contact the professionals in the auto repair shop.
Another thing to look at if nothing helps is the condition of the wiring in the engine compartment. Elementary oxidation of the contacts or wire breakage may cause the motor to appear “dead”.
Engine "Lancer-9": reviews
According to most owner reviews, the Mitsubishi-Lancer-9 engine shows itself to be reliable and stable. Of course, any mechanism can break. The reason for this is wear and loss of life. Therefore, it is logical that the Mitsubishi-Lancer-9 engine ceases to start over time. Regular maintenance and repairs will help avoid trouble.
