Ra250s cold car starts and stops.

There are many possible reasons for the flameout of the RA250S cold car after it is started. Here are some common reasons and possible explanations:

1. Oil supply problem: The fuel pump may be faulty or the oil supply pipeline is blocked, resulting in insufficient oil supply and flameout. At this point, check the fuel pump and oil supply pipeline to solve the problem.

2. Ignition system problem: It may be that the spark plug is aging or the ignition coil is faulty, resulting in abnormal ignition and flameout. Try replacing the spark plug or ignition coil to solve the problem.

3. Air supply problem: It may be that the air filter is blocked or there is something wrong with the intake pipe, which leads to insufficient air supply and flameout. You can check whether the air filter needs to be replaced and clean the intake pipe to solve the problem.

4. Engine sensor failure: It may be that the engine sensor fails, which causes the engine control system to fail to work normally and stall. The working condition of the engine sensor can be checked by the diagnostic instrument, and the faulty sensor can be replaced if necessary.

It should be noted that the above are only some possible reasons, and there may be other factors in the actual situation. In order to find out the cause of the problem accurately, it is recommended that you send the vehicle to a professional garage for inspection and maintenance.
