故障现象一辆北汽陆霸车,车主反应发动机突然熄火后无法起动,但蓄电池有电,起动时起动机也运转。故障诊断及排除接车后首先验证故障,确实如车主所述。拔掉一根高压线,接上一个火花塞,起动发动机,查看点火能量,点火能量强劲。接着将高压线插回,拆开空气滤清器,往空气滤清器里面喷点化油器清洗剂后再次起动车辆,立刻起动着机了,至此诊断该车为油路故障。该车进油管和回油管不好拆卸,所以就没测量油压,而且突然熄火应该不是燃油泵问题。因为假如燃油泵有问题的话,熄火是慢慢熄火而不是突然熄火。继续检查发现一个ECU电源的熔丝熔
Symptoms A Beichadu Ruba car, the owner reaction engine can not be started after a sudden flameout, but the battery has electricity, start when the starter is also running. Troubleshooting and troubleshooting First verify the fault after the car, indeed, as described by the owner. Unplug a high-voltage line, connect a spark plug, start the engine, view the ignition energy, ignition energy is strong. Then the high-voltage line back, open the air filter, the air filter inside the carburetor spray after starting the vehicle again, and immediately started the machine, thus diagnosing the car as the oil fault. The car into the pipe and return pipe is not good demolition, so no measure of oil pressure, and suddenly turn off the fuel pump should not be a problem. Because if there is a problem with the fuel pump, the flame is slowly extinguished instead of suddenly extinguished. Continue to check the fuse melting of an ECU power supply
