To check for a spark, unscrew the spark plugs, put the high-voltage wire tips on them and bring them to the "ground" (-). Do not hold the tip or the spark plug in your hand. They must be held with well-insulated pliers. Ask an assistant to start the engine.
Attention! To avoid damage to the catalyst, fuel injection is not allowed, so before starting, you must disconnect the fuel pump relay. If the spark plugs do not produce a spark, then the defect should be looked for, guided by the chapter "Ignition system".
For vehicles with a diesel engine, check the preheating and fuel systems.
The engine starts poorly or does not start at all
Incorrect actions when starting the engine
Petrol engines
Press the clutch. Set the automatic transmission to position P or N. Turn on the starter. Do not press the accelerator pedal. As soon as the engine starts, release the ignition key. When starting a cold engine, immediately start driving after the engine starts. Warming up the engine for about 30 seconds after starting is allowed only in severe frosts. At temperatures below -20°C, turn on the ignition, wait until the anti-theft system turns off, and then start the engine.
Attention! When power is turned off (disconnected battery, defective fuse, etc.) the doors must be opened using the remote control before the engine can be started.
Warning! Frequent attempts to start the engine can damage the catalytic converter, because unburned fuel gets into it and when heated, it can cause an explosion.
Diesel engines
0 When starting a cold engine, turn on the preheating and as soon as the preheating indicator lamp goes out, depress the clutch or set the automatic transmission to position P or N. As soon as the indicator lamp goes out, start the engine without pressing the accelerator pedal and release the ignition key as soon as the engine starts. When starting a warm engine, preheating is not necessary. The engine can be started immediately.
The ignition system is faulty
Cars with gasoline engines
Check the ignition system.
The preheating system is faulty
Diesel Engine Cars
Check the preheating system.
The fuel system is faulty or contaminated
Check the fuel system.
The starter turns too slowly
Charge the battery. Check the starter.
Compression pressure too low
Check and adjust valve clearances. Check valve condition. Replace cylinder head gasket or overhaul engine
The valve timing is set incorrectly
Check the ignition timing angle. Replace the timing belt.
