Description
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.
