The most important thing is not to get nervous! Turn on the hazard warning lights, press the clutch pedal and, using the car's inertia, try to carefully move to the edge of the roadway and stop as far to the right as possible at the curb, and if possible, outside the roadway.
Warning: Please note that when the engine is not running, the effectiveness of the vehicle's braking system is reduced and more force on the brake pedal may be required to brake. Set the parking brake; if the vehicle is stopped on a slope, use wheel chocks. In difficult traffic conditions and on country roads, put up an emergency stop sign as provided for by the Road Traffic Regulations. Now it is necessary to identify and repair the malfunction that has arisen.
There are two main reasons:
- the ignition system on the car does not work;
- the engine power supply system is not working.
First, find out if there is gas in the gas tank. Turn on the ignition and look at the fuel gauge. If the yellow fuel reserve light is not on and the gauge arrow shows there is fuel, it can be assumed that there is gasoline in the fuel tank.
Open the hood of your car and carefully inspect the underhood space. Pay attention to the integrity of all parts and units. Check if all the wires are in place, if there are any broken, burnt out, or with damaged insulation. Inspect the fuel hoses, engine fuel lines and fuel filter (installed under the bottom of the car) - are there any gasoline leaks?.
Inspect the expansion tank of the cooling system, check if the coolant has leaked. Also check the oil level in the engine crankcase. If everything is in order, proceed to check the ignition and power supply systems, which is described earlier, but first check the condition of the timing belt. If the timing belt is broken, the engine will not start for no apparent reason.
In addition, a sudden engine stop and the inability to start it again may be caused by a failure of the crankshaft position sensor or a disconnection of the wiring harness connector from it.
