汽油泵繼電器是一種電子設(shè)備，它在汽車引擎啟動(dòng)時(shí)起到了關(guān)鍵作用。它的主要功能是控制汽油泵的電源，確保引擎可以正常運(yùn)轉(zhuǎn)。

汽油泵繼電器通常安裝在汽車的引擎控制模塊（ECM）中。當(dāng)啟動(dòng)汽車引擎時(shí)，ECM會(huì)向汽油泵繼電器發(fā)送信號(hào)，以啟動(dòng)汽油泵并將燃料輸送到引擎中。一旦引擎啟動(dòng)，ECM將停止向汽油泵繼電器發(fā)送信號(hào)，從而停止汽油泵的運(yùn)轉(zhuǎn)。

如果汽油泵繼電器出現(xiàn)故障，汽車引擎可能無(wú)法正常啟動(dòng)或運(yùn)行。因此，定期檢查汽油泵繼電器是否正常工作非常重要。

The fuel pump relay is an electronic device that plays a crucial role in starting the car engine. Its main function is to control the power supply of the fuel pump and ensure that the engine can operate normally.

The fuel pump relay is usually installed in the engine control module (ECM) of the car. When starting the car engine, the ECM sends a signal to the fuel pump relay to start the fuel pump and deliver fuel to the engine. Once the engine is started, the ECM stops sending signals to the fuel pump relay, thereby stopping the operation of the fuel pump.

If the fuel pump relay fails, the car engine may not start or run properly. Therefore, it is important to regularly check whether the fuel pump relay is working properly.
