DonCherry和各位DX:

小弟的老车入冬以来打火起车一直正常,只是有时天气寒冷时车钥匙要搭在打火位置时间长一点(5-10秒),但最后总能起来. 今天早晨起车,不知道是不是天气太冷的原因,车钥匙搭在打火位置将近20秒,
车还是启不来,最后Engine黄灯亮啦(以前也出现打火时间长,起来后Engine黄灯亮的情况,熄火再打着该灯就灭啦.)无奈拔出车钥匙过后再试现象依旧(打火过程中车突突的声音和以往一样,但就是起不来,当然车电池电量充足,肯定不是电池的原因)

还麻烦各位DX帮分析一下原因,我准备下午天气暖和时再试试.(该车的火花塞也快两年未换啦)

不胜感激,先谢啦!

老弟，该换spark plug wire, distributor cap 和 rotor 了。当然如果把spark plug 也换了更好。 火花塞如果不好，只是会造成点火困难，但不会造成点不起火。点火线和分电盘盖子，去canadian tire 买都很便宜而且自己都能换。其操作很简单，但要注意，最好是一根一根换。即拔掉一根旧的立即换上一条新的。这样可以避免把次序搞乱。当然点不着火还有可能是油路fuel system的问题，但看来不象。祝你好运！

Change the wire set and spark plug first. especially wires.
Then clean the distribute cap and rod with WD40(water disperse) or simple repace with new.
Pour some gas tank/gas line de-ice into the tank.

See what happens.

谢谢DonCherry,Carman and freefrenchcourse

车已经能启动啦!今天下午就换Spark Plug.

由于是十多年头的老车除了换机油,使用Fuel Injector and System cleaner外未做什么保养.现准备用SLICK 50 PLUS 的"Engine Treatment for Older Engines" 和WYNN'S ENGINE TUNE-UP and CARBURETOR CLEANER

不过搞不准Accord 90有没有CARBURETOR?
如果有,CARBURETOR CLEANER有用吗?

再一次谢谢这些热心的朋友!

DonCherry

Yes, CARBURETOR CLEANER is useful, but most car here have relatively clean carburetor, which is different from the car I found in China, when most cars are carburetor at that time. We may pour some gas into carburetor if it is too dirty and vacuum is too weak.

I think your firing system is too weak.
