THE CAR DOES NOT TURN ON
The causes can be many and, moreover, different according to the type of supply, petrol or diesel. First you need to understand if the starter motor is blocked or working. If it does not turn, the cause is almost always the low battery. To check it, just turn on the headlights. If the light is completely missing or weak, it is the battery: it must be recharged or changed. Otherwise, the accused is the starter: it can be locked and then you can try to unlock it by engaging a low gear (if the gearbox is mechanical) and pushing the car back and forth: if the operation is successful, a metallic noise will be heard which will testify to the unlocking. If even this operation is unsuccessful, you should contact an electrician.
IT CAN BE FLOODED
If, on the other hand, the motor works and the machine is running on petrol, it may have become flooded: in this case it is necessary to accelerate fully and repeat the starting phases until the ignition. Or, the power system may be tilted. The fault can start from the fuel pump, from the fact that dirty petrol has been “fished”, or be due to a problem with the injection system, the coils, the spark plugs, the electronic control unit or the imperfect recognition of the transponder of the immobilizer present in the key. To solve these problems you need to contact a professional.
ON DIESEL MACHINES
The same advice also applies when the starter motor of a diesel car turns normally because the causes of the ignition failure can derive from inefficient preheating glow plugs, from a failure of the fuel system or from the clogged diesel filter. At low temperatures, diesel fuel that has frozen because it is not of the “winter” type can also prevent starting a diesel engine. In this case, if it is possible to hospitalize the car in a heated place after a few hours, the situation will return to normal, because the paraffin contained in the diesel fuel will freeze, otherwise it is good to go to a workshop. Once the problem has been solved, it is useful to add a specific additive to the tank to keep the diesel fluid and then
WATCH OUT FOR FUEL
A last event, paradoxical but not rare, which can compromise the starting of an engine is the lack of petrol or diesel: it can happen due to a failure of the level indicator, but also due to carelessness on the part of the seated person in the driver’s seat.
THE FATIGUE CAR TO SWITCH ON
If the engine struggles to start both when it is cold and when it is hot and the battery is in good condition, problems may be due to the failure of petrol to reach the injection system due to micro-leaks in the pipes, to a pump failure. fuel, to a defect in the sensor that reads the rotation of the flywheel, to a coil or to some damaged electrical-electronic system element. Another reason may be the imperfect recognition of the immobilizer transponder present in the key. To solve these anomalies it is necessary to rely on a professional.
BURNISH ODOR AT THE START OF THE CAR
The two most common reasons for this problem are a leak on the engine oil drain line which, due to high temperatures, burns quickly, or a short circuit. In both cases, we suggest using a professional as quickly as possible to avoid serious damage to the car (as well as for the safety of the occupants).
