汽車油泵故(gu)障的癥狀有加速無(wu)力、啟動(dong)困難、行駛異(yi)響、發動(dong)機故(gu)障燈亮起、發動(dong)機抖動(dong)等，修理方法是到 4S 店或專(zhuan)業維(wei)修店檢查并更換受(shou)損部(bu)件。

加速(su)無力表現為(wei)急加油(you)(you)(you)時有頓挫感(gan)，這是由(you)于油(you)(you)(you)泵(beng)故障(zhang)無法為(wei)發(fa)動(dong)(dong)(dong)機(ji)提供(gong)充足燃(ran)油(you)(you)(you)。啟(qi)動(dong)(dong)(dong)困難(nan)則體現為(wei)需(xu)長時間(jian)打鑰匙，甚至多次(ci)嘗試才(cai)能發(fa)動(dong)(dong)(dong)汽車，因為(wei)油(you)(you)(you)泵(beng)不(bu)能正(zheng)(zheng)常供(gong)應啟(qi)動(dong)(dong)(dong)所需(xu)燃(ran)油(you)(you)(you)量。行駛時聽(ting)到的嗡(weng)嗡(weng)異響，正(zheng)(zheng)是油(you)(you)(you)泵(beng)故障(zhang)產生的異常聲(sheng)響。發(fa)動(dong)(dong)(dong)機(ji)故障(zhang)燈(deng)亮起，明確提示可能存在油(you)(you)(you)泵(beng)故障(zhang)。而發(fa)動(dong)(dong)(dong)機(ji)抖動(dong)(dong)(dong)是因燃(ran)油(you)(you)(you)供(gong)應不(bu)穩定，致使發(fa)動(dong)(dong)(dong)機(ji)運(yun)轉不(bu)平穩。

當出現(xian)(xian)這些(xie)癥狀時(shi)，要及時(shi)前往專業的(de) 4S 店或(huo)維(wei)修(xiu)店。專業技師會憑借(jie)經驗和工具，判斷是油(you)泵本(ben)體還是泵芯出現(xian)(xian)故障，若有損壞，就(jiu)會進(jin)行(xing)更換。總(zong)之，汽(qi)車(che)油(you)泵故障不(bu)可忽視(shi)，及時(shi)維(wei)修(xiu)才(cai)能保障車(che)輛正常運行(xing)。
