What happened to the sudden flameout of Buick Excelle 1 and 8 automatic gears?

There are many cases of flameout during driving, which may be that the oil pump fails to supply oil or the high pressure does not catch fire, or there may be problems with the driving computer or the body module. Because you can't see the real car, you can't judge it accurately. In order to avoid affecting the use, it is recommended that you contact the local after-sales service again and make it clear.

Maintenance process:

1. When the ignition switch is turned on, the fuel pump relay works normally, the fuel pump EF 15 fuse (15A) has voltage (the test light is turned on), and there is no high-voltage fire when starting. Measure the voltage at pin B of ignition coil plug with a test lamp.

2. Check whether the ignition coil power supply EF 14 fuse (15A, distributor fuse) has voltage.
