What is the reason for BYD F3' s poor ignition in the morning?

There are many possibilities according to the design characteristics of the vehicle model and the different parts that cause the failure.

Wire:

A, ignition coil failure;

Such as: open circuit, poor conduction, etc.

B, spark plug failure;

Such as: too much carbon deposit, incorrect calorific value, reaching the end of life, etc.

C, electrical wiring is not normal;

Such as: loose plug wire in ignition part, open circuit or poor grounding, etc.

D. abnormal sensor;

For example, sensor abnormalities such as intake part, crankshaft part and camshaft part may be caused.

E. battery failure;

Such as: no electricity storage or insufficient electricity, battery damage and other reasons can be caused.

F, starter failure;

Such as: starting weakness, internal failure, starting line failure, etc.

G, water temperature sensor is not normal;

Such as: abnormal temperature sensing tongue, inaccurate data, abnormal data collected by ECU, abnormal mixing ratio, etc.

?

Engine:

A. improper maintenance;

For example, the oil is not changed for a long time or the viscosity of the oil is too high, the quality of the used oil is too low, and the label does not match. There are also poor lubrication and blocked oil passages.

B, abnormal cylinder pressure;

For example, premature or abnormal cylinder wear and air leakage caused by various reasons.

C, excessive carbon deposition

D, throttle body failure;

Such as: dirty throttle, stuck, abnormal stepping motor, excessive carbon deposition, etc.

E, timing belt failure;

Such as: aging, tooth jumping (1-2), looseness (tightening force), etc. Wear and looseness of all connected transmission parts, abnormal installation, etc.

F, internal failure;

Such as: oil pump failure, abnormal pressure, abnormal pumping, etc.

Oil circuit:

A, nozzle failure;

Such as: blockage, self-decline.

B, oil pump failure;

Such as: insufficient pressure, poor conduction and fever.

C, oil filter failure;

Such as: dirty gasoline filter, long-term non-replacement, blockage, etc.

D, gasoline quality is unqualified;

Such as: the gasoline label does not match, there are too many impurities in the gasoline, the oil tank is rusty, and the gasoline has too much water.

The possibility of other faults is not ruled out, and the test results of the real vehicle shall prevail.
