Engine Troubleshooting

If the engine does not start, then it is necessary to systematize the malfunctions. In order for the engine to start at all, two basic prerequisites must always be met in gasoline engines: an air-fuel mixture must be supplied to the cylinder, and an ignition spark must jump on the ignition electrode. How to carry out systematic troubleshooting is described in chapter "fuel injection system".

Malfunction: the engine starts poorly or does not start at all.
