What caused the difficulty in starting mercedes benz c class engine?

The difficulties in starting mercedes benz c-class engine are usually caused by carbon deposition, weak ignition energy of spark plug, insufficient low pressure in fuel circuit, battery power loss, and blocked exhaust pipe.

Common causes of engine starting difficulties:

1. Ignition difficulty caused by car carbon deposit, accompanied by slight jitter when idling. Cleaning the throttle, cleaning the carbon deposit at the air inlet and cleaning the fuel injector can solve the problem.

2. The ignition energy of the spark plug is very weak. In order to save money, some car owners do not replace the spark plug after the maintenance cycle, which will cause the spark plug to turn off when the ignition energy drops seriously. At present, most of the engines of many models are in-cylinder direct injection, so the requirements for spark plugs are higher.

3. Insufficient low pressure in the fuel circuit and insufficient oil pressure in the low-pressure oil circuit directly lead to secondary ignition of the engine. The specific reason is that the first ignition failed because the low-pressure oil circuit is building oil pressure, and the second ignition can be carried out once. Specific inspection components: fuel pressure regulator, gasoline pump, gasoline filter element and internal pipeline.

4. The battery is dead, which is more common. When you can't get a taxi, the owner's first reaction is that the battery is dead. The solution is also very simple, just find a car or other batteries to get electricity.

5, exhaust pipe blockage, exhaust pipe blockage is generally rare, unless it is a coincidence or someone is playing a prank, but this situation is also better to investigate.
