What is a Fuel Pump Relay?
To test the relay in the event of a non-starting vehicle, drivers can turn the key to the on position and listen for a buzzing or humming sound coming from the vehicle's fuel tank. If there is no noticeable sound, the problem could be the fuel pump or the relay. It is much easier to test the relay than to change the fuel pump.
In most vehicles, there will be two or more relays in the same location. Most are the same, and the vehicle's owner's manual will provide information about where they are. A driver can unplug the relay to test if it's causing a problem. If there is another relay next to it, he can unplug it and plug the fuel pump wiring harness into it. He should then turn the vehicle's key to the on position and again listen for the sound of a running pump.
If the pump runs, it is time to buy a new relay at the auto parts store. If the pump still isn't working, the driver needs to check the fuel pump. This will require removing the fuel tank. Individuals should use caution when working around fuel and be sure to keep the work area clean to prevent accidents.
What Is Pump Testing?
Pump testing is a method by which a wide variety of pumps is evaluated for efficiency, safety, and overall function. The process is commonly completed annually as a part of regular maintenance. Pumps can also be tested before they are purchased in order to ensure that they are able to handle anticipated flow. The tests can be performed on equipment such as fuel, sump, or water pumps.
Two of the most common specific elements evaluated during pump testing are fluid pressure and flow. By measuring these things, it is possible to determine if a pipe has proper capacity for the level of fluid it processes. These elements can also show whether energy is being used efficiently.
