Where Is The Fuel Relay? The fuel pump relay is an electronic component that is found on virtually all vehicles equipped with an internal combustion engine. It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump.
Where is the fuel pump relay located? Location.
Most fuel-pump relay units are located under the dashboard near the steering column.
In some cases, the unit is located in the area where the steering column is mounted or near the engine’s firewall.
What are the symptoms of a bad fuel relay? How to tell if fuel pump relay is bad (6 Signs)

Where is relay located? It can be in the fuse box (also called a power box), the fuse panel under the dash, or on the right fender. Most cars will have it located under the hood, inside the long box with a black cover. Often called the fuse box, this is where a vehicle’s fuses and relays are mounted.
Where Is The Fuel Relay? – Related Questions
What causes a fuel relay to go bad?
Dust, electrical power surge, and other factors can cause a fuel pump relay to go bad. Dust and sudden voltage increases can affect a fuel pump relay’s performance and cause an engine to malfunction.
Where is the fuel pump reset button?
Look for the fuel pump switch or inertia switch. This is a small box with a plastic button on top and an electrical connector at the bottom. On some vehicle models, this will be located in the luggage compartment. Look on a side panel for a small, round button which you can pry off with a small screwdriver.
Is it the fuel pump or the relay?
The fuel pump relay is an electronic component that is found on virtually all vehicles equipped with an internal combustion engine. It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump.
How much does a fuel relay cost?
A fuel pump relay will typically cost about $25 for the part, and a mechanic may charge a minimum of an hour’s worth of labor to replace it. The vehicle not starting may be a fuel pump or relay along with other possible ignition problems.
How do you check a relay?
The only tool required to check a relay is a multimeter. With the relay removed from the fuse box, the multimeter set to measure DC voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located).
Does a relay need a fuse?
Yes, The “main” power to the relay fuse, then to the compressor when you switch to “on” will protect the rely and the compressor “if” fused at the power source or at least before the relay. The reason to protect as close as possible to the power source with a fuse/breaker is just in case you have a short in the wire.
Does a relay click when it’s bad?
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor.
As a result, your engine won’t turn over – no matter how many times you turn the key.
A faulty relay often produces an audible clicking sound when you turn your car.
What is the difference between a fuse and a relay?
What are the differences between fuse and relay
Is it safe to bypass fuel pump relay?
Registered. Jumpering or bypassing the fuel pump relay puts a constant +12VDC to the fuel pump. Basically you have voltage directly from the battery to the fuel pump, even with the engine turned off. You could use a jumper assembly with a toggle switch to manually turn on and turn off the fuel pump.
How do I know if my fuel pump control module is bad?
What are the signs of a bad fuel pump
Is there a fuse for the fuel pump?
In most car models, the fuel pump relay is located in a fuse box somewhere under your dashboard, but it can also be located in the fuse box in the engine bay. The engine’s or the dashboard fuse box is usually a long black box containing a fuel pump relay and various other fuses and relays.
What would make a fuel pump not turn on?
If the fuel pump is not coming on, and the fuse and relay are good, then it may be possible that there is a problem with the pump or the fuel pump circuit. If it is not then there may be some sort of wiring issue before the fuel pump relay, perhaps a wiring issue or other problem with the ignition switch.
How do you reset a fuel pump relay?
Push the button on the inertial switch; it should be clearly marked as the fuel pump reset, and may be in a contrasting color to the case. You may need to turn the ignition key to the on or accessory position to energize the module and reset the switch.
How do I reset my fuel pump?
To reset the fuel pump on a car or truck, locate the initial trigger of the vehicle, and press the inertia switch button. If the switch doesn’t have an external button, remove its cover to access the button or the breaker switch. If required, replace a blown fuse.
What are the signs you need a new fuel pump?
Usually, a bad or failing fuel pump will produce one or more of the following 8 symptoms that alert the driver of a potential issue.
Whining Noise From the Fuel Tank.
Difficulty Starting.
Engine Sputtering.
Stalling at High Temperatures.
Loss of Power Under Stress.
Car Surging.
Low Gas Mileage.
Car Will Not Start.
How long do fuel pump relays last?
Over time, the fuel pump relay can begin to show signs of wear and will have to be replaced. The fuel pump relay is designed to last the life of the car, but due to the grueling conditions it is exposed to, it will not usually last that long.
How do you tell if a relay is bad with a multimeter?
Use a digital multimeter (DMM) to test the resistance between each pole of the relay and the corresponding NC and NO contacts for that pole. All NC contacts should read 0 ohms to the corresponding pole. All NO contacts should read infinite resistance to the corresponding pole. Energize the relay.
