A Bad Fuel Pump relay can interrupt the operation of your car’s fuel system by providing inconsistent electrical power to the pump. And it is responsible for activating the pump when we turn on the ignition so that the engine receives fuel to function. Recognizing an ailing relay before it fails can save you from bigger problems within the fuel system.
A malfunctioning fuel pump relay has several symptoms, but one of the most common is cranking the engine. Without soon-to-die relay, the pump would not be able to pressurize the system in 40–60 psi range (which is about normal) and thus while cranking over, engine either takes a lot longer or it just would not start. A gauge will confirm this by showing that fuel pressure is below manufacturer specifications, meaning the flow of power has been interrupted.
Another symptom of a bad relay is intermittent stalling. Old contacts on a relay may open up while driving, disconnecting power from the pump and shutting down the engine. Many mechanics will default to blaming 20-30% of unexplained stalling issues on fuel system electrical faults where the relay is a common villain.
Another sign that you have issues with your relay is a clicking from the fuse box. Clicking can usually be attributed to internal wear as relays are built to open and close circuits over time. Now when this sounds go on, you change the relay to save your own calmness from further electric shattering.
The following real world cases demonstrate the necessity of rapidly identifying faulty relays. This is the same defective fuel pump relays that caused wide spread stalling and no-start conditions in a 2020 recall for 150,000 vehicles. It was traced to a bad internal connection that wore out over time with normal use.
The best thing you can do to determine the fault is test the relay with a multimeter. By using the multimeter in continuity measuring mode and applying power to the relay terminals, we check the internal contacts. Any relay that does not pass this test should be replaced right away.
By swapping in a proper relay, you can also eliminate the chance of introducing an intermittent power cut to the fuel pump. Pairing it with a quality pump like Kemso Fuel Pumps enhances the system efficiency and fauthenticity.
