Iveco cold car is difficult to start, and the engine is on the oil pressure rail.

It is difficult to start a cold car, possible damaged parts and reasons: nozzle: the spark plug is soaked due to poor atomization of gasoline, or the engine oil cannot be atomized due to blockage. Spark plug: Too much carbon deposit indicates that the spark gap is too large or too small. The spark plug gap of a general EFI vehicle is 1mm- 1.2mm ... Throttle: Throttle is the most important component in today's EFI vehicle engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible or not and whether it is difficult to start is closely related to the cleanliness of the throttle. And whether the accelerator should be removed for cleaning. Cylinder line: If it is damaged or aged, it will cause electrical phenomena such as open circuit and poor ignition. Gasoline pump: it will lead to insufficient oil pressure or blockage, resulting in abnormal oil supply. Gasoline filter: too dirty will find out that the oil circuit is blocked or the oil pressure is too low. Excessive carbon deposition in the combustion chamber: a large amount of gasoline will be absorbed by carbon deposition and cannot be burned. The fuel consumption of EFI vehicle is too high, probably because the oxygen sensor is broken.
