打不着火只发生在夏天,冬天没事。
每次开一段后放一个小时再打火就打不着,放几分钟或者很长时间能打着火。
或者先把钥匙转到on 位置 然后打火 能打着。
不知道什么毛病,有没有人有同样的毛病啊?

when your vehicles fail to start:
1. If the car doesn't crank
1a. Double check your transmission is in P or N, and there is no other anti-
theft device engaging, sometimes you can try to shift the car from P to N
then shift back as the shift position sensor doesn't work well always
1b. Try jump-start to make sure it is not problem of battery
1c. you may have a bad starter, or a bad contact. Don't jump through
replacing the starter immediately as it is usually expensive. Pop up the
hood, if you can access the starter then use a stick to tap it while having
your friend turn the key, sometimes it can solve the problem temporarily.
2. If the car does crank but won't start
2a. Have your friend turn the key to on, keep close to your gas tank and
listen carefully, if you don't hear a quite noise, then PROBABLY your fuel
pump is dead or it is not powered, check fuse.
2b. Check your spark plugs with a tester, they are usually cheap, like this:
http://www.amazon.com/Neiko-Tools-Line-Spark-Tester/dp/B000MHND
2c. Check your fuel pressure to make sure you have enough fuel. You can use
fuel pressure gauge. But most likely you don't have this tool in your home,
then some people suggest you may disconnect the fuel line near fuel filter
to see if there is any gas splashing when you turn your key to on. I don't
recommend that as it is dangerous, the gas may be ignited by sparks under
the hood, say from the alternator. But if you've reached this step, then you
already have no choice but having your car towed to a mechanic shop as it
is
very hard to replace the fuel pump by yourself if there is something wrong
with the pump
3. Check your fuel pressure

肯定不是电池的问题, 我暑假放假回家车放了3个月回来还能打着火。

很奇怪只在夏天有这毛病,个人认为是缸内油气不足,所以要先on 一会给油泵通电就
能打着。

05年的车,电池应该还好。
先on半分钟自检一下是必须的。
