When the engine does not start, a systematic approach is needed to identify the malfunction. In general, in order for a gasoline engine to start, 2 basic prerequisites must always be met: an air-fuel mixture must enter the cylinders, and a spark must be present on the spark plugs. Therefore, first of all, it is always necessary to check whether fuel is supplied at all. How to do this is described in the sections "
Carburetor" And "
Petrol injection system".
Attention: On vehicles with a catalytic converter, the starter should not be kept on uselessly for a long time, because. this can lead to failure of the catalytic converter.
Fault. The engine starts poorly or does not start at all.
