问:intermitant未能“火”

汽车运行好,3次(至少两周之久,然后1周)未能启动。它试图翻,但是不会。没有检查引擎灯。不是冷启动。每次启动后关闭a / c(以为电池或发电机)。这最后一次关闭a / c没有事,让它坐了一个小时,没有问题。把它拖到我的家。早上还是做同样的事。然后我拿出保险丝EFI(虽然似乎好)启动。? ? ? Put fuse back then tried starting again and failed. Pulled and put fuse back in (thinking maybe not seated correctly) and started up just fine. To me it appears the fuel pump has power and is working. I am wondering if it may be a clogged fuel filter that is just on it's last leg of filtering and doing its best. Your thoughts?
