If you're having trouble with your fuel pump, one of the first things you'll want to check is the power supply to the pump. Most fuel pumps have an electrical connector that supplies power to the pump. This connector can sometimes become loose or corroded, causing the pump to lose power and fail.
To check the power on your fuel pump connector, first make sure that the connector is plugged in securely. If it's loose, try tightening it with a wrench. If the connector is corroded, you may need to clean it with a wire brush or sandpaper.
Once you've checked the connector, turn on the ignition and see if the fuel pump is running. If it's not, there may be a problem with the pump itself or with the wiring.
