笔者最近连续碰到丰田(TOYOTA)公司CAMRY2.2 L(佳美)、PREVIA(大霸王)、CROWN 3.0(皇冠)三款典型车有关燃油泵故障的问题。故障现象都是点火开关打到ST位置时,能起动发动机,松开点火开关回到ON位置,随即熄火。经查看仪表,汽油表指示不在低限,接上燃油压力表,用起动机带动发动机运转时,燃油压力正常(265 kPa～304 kPa),喷油器喷油和点火均正常,当点火开关回到ON位置时,燃油压力表立即指示卸压。根据这些现象认为是当点火开关在ON位
I recently met Toyota (TOYOTA) CAMRY2.2 L (Camry), PREVIA (King), CROWN 3.0 (Crown) three classic car fuel pump failure problems. Symptoms are ignition switch hit the ST position, you can start the engine, release the ignition switch back to the ON position, and then turn off. After checking the meter, the fuel gauge indicates not at the low limit, connect the fuel gauge, and start the engine with the starter, the fuel pressure is normal (265 kPa ~ 304 kPa), the fuel injection and ignition of the injector are normal. When the ignition switch is turned back To the ON position, the fuel gauge immediately indicates the pressure relief. According to these phenomena is considered when the ignition switch is in the ON position
