Mazda 6 shuts down as soon as he refuels, and sometimes when he is driving. What is the reason?

1 There is something wrong with the ignition system. Check ignition coil and spark plug. And whether the connecting wire is loose.

2 Check whether the oil pressure is normal again and check the control circuit of the oil pump at the same time. You can also clean the fuel injectors and check the fuel injection.

3 Check whether the connecting harness of the engine computer is loose, and turn on the ignition switch to check whether the power cord of the computer has electricity and the grounding is normal. If it is good, then try another computer to judge whether it is good or not?

If it still can't be solved, it's best to go to the 4 S shop, check the fault code with a special decoder, and focus on reading the relevant dynamic data stream through the fault code. Determine the point of failure.
