5 Reasons Why Your Car Won't Start
Dead battery. A dead battery is the most common reason why your car won't start. ...
Defective ignition switch. If you know your battery is working properly, but your car doesn't turn over on the first few tries, you might have a problem with the ignition switch. ...
Faulty starter. ...
Clogged fuel filter. ...
Empty gas tank.
复杂了。找地方检查吧
P.S.
crank sensor如果有问题，无法启动的症状也与此类似，轰轰轰轰轰轰，感觉再有一口气儿就启动了，但就是启动不了。但这东西如果没有物理损伤一般也不出问题。泡水了？水里有漂浮物刚巧不巧卡在sensor上了？或者插头松了？或者线有破损？
The most common symptom associated with a bad or failing crankshaft position sensor is difficulty starting the vehicle. The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
A failing sensor can cause intermittent problems: a car may cut out or stall randomly, but then restart with no problems. The engine might have troubles starting in wet weather, but starts OK after. Sometimes you might see the RPM gauge behaving erratically. In some cases, a failing sensor can cause long crank time before the engine starts. If the sensor is bad, the engine will crank but won't start. Read more: Why an engine cranks but won't start: common problems.
又学习到了。
如果某个火花塞或者它的线皮破损导致短路，发动机会crank，但也启动不了。
还有上面坛友说的，得逐一排查了，有经验的mechanic一听声儿可能就初判个八八九九。 |
