  • Many vehicles available today come with fuel pump shut-off switches. These devices are essentially circuit breakers that sit inside you car’s airbag control module’s inertia switch, which is supposed to trigger when the vehicle comes to a sudden stop.

Where is the fuel pump cutoff?

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.

Where is the fuel shut off solenoid?

The fuel shutoff solenoid is located at the front of the injection pump, just in front of the upper intake manifold.

Where is fuel relay switch located?

In most vehicles, the relay is located in the large fuse box in the engine compartment.

How do I reset my fuel switch?

Turn the ignition switch OFF. Ensure that there is no fuel leaking in the engine compartment, along any of the lines or at the tank. There should be no odor of fuel as well. If no leakage and/or odor is apparent, reset the switch by pushing the reset button on the top of the switch.

How do you reset a fuel pump switch?

How to Reset a Fuel Pump Shut Off Switch

  1. Locate your car’s inertial trigger or airbag control module.
  2. 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.

How do I know if my fuel shut off solenoid is bad?

Common signs include poor cold start performance, the Check Engine Light coming on, and failing an emissions test.

Why am I not getting power to my fuel pump?

If you there is no power to the fuel pump or the relay, then there may be a possible electrical issue with the vehicle. If there is an issue with the switch or the circuit, perhaps a wiring problem, then power to the fuel system may be cut off.

What is a fuel pump solenoid?

A fuel shutoff solenoid is an electromagnetically-operated valve used to remotely cut the fuel supply to an engine. When the solenoid is energized, the motion of its plunger retracts the spring-loaded valve poppet from its seat, allowing fuel to pass through the valve.

Where is the fuel pump relay fuse located?

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 happens when fuel pump relay goes bad?

Because y our vehicle’s fuel pump relay is a vital component that prompts your fuel pump to start once you fire your engine. It is prone to wear and tear that could cause it to get damaged like all devices. Once the fuel pump relay goes bad, the fuel supply to the engine is cut off, and your engine stalls.

What fuse controls the fuel pump?

Replacing Fuel Pump Fuse Most fuel pumps will run a 15 (Blue) 20 (Yellow) or 25 (Clear) amp fuse. Using a fuse that’s too small will cause the fuse to blow again. This is a normal condition as the fuse isn’t rated for the higher amps of a fuel pump circuit.

What is the fuel pump reset button for?

In the event of an accident, the “Fuel Reset Button” will turn off the fuel pump and system.

Where is the fuel pump control module?

The module is typically installed on or very close to the fuel pump, and in the early years of the component’s use, this practice led to a design fault. Manufacturers, including Ford, initially placed the module inside the vehicle immediately above the fuel pump, typically just beneath the floor pan.

What is a fuel cutoff switch?

The fuel pump shut off switch is designed to disengage the power to the fuel pump when a vehicle comes to an instant stop. The fuel cut-off switch is a safety reset switch which starts the fuel pump and allows gas flow to the engine.

Quick Fix: 3 Easy Tips to Find and Reset Fuel Cut Off Switch on Any Car

The engine turns over, but the automobile would not start. Does this sound familiar? If you drive over a large pothole, hit a speed bump, or are involved in a car accident, you may find yourself with an engine that won’t start. In most circumstances, all that is required is to press the reset button on the gasoline shut off switch, which was engaged as a result of the collision. It appears to be straightforward, doesn’t it? Well, that’s not precisely true. According to my observations, the most difficult challenge is not how to reset the fuel pump shut off switch, but rather how to locate a concealed fuel pump shut off switch.

So, where is the button to reset the gasoline pump?

Furthermore, I will demonstrate how to locate and reset the gasoline shut off switch on GMC, Ford, Peugeot, VW Golf, Citroen, Vauxhall, Subaru, Renault, Dacia, Mazda, and a variety of other vehicles equipped with an electronic fuel pump, including: To begin, I’ll clarify what the phrase “fuel pump emergency shut off switch” means.

What is Fuel Pump Emergency Cut Off Switch?

This device is analogous to an electric fuse, except that it is used for fuel rather than electricity. Many automobiles are equipped with gasoline pump shutoff switches. The inertia switch is a safety feature included into automobiles that allows the gasoline supply to be cut off in the event of a car crash or accident in which the vehicle comes to a complete stop suddenly and unexpectedly.

5 Important Steps Before Resetting the Fuel Cutoff Switch

Before pressing the “red button,” double-check to see if there is another issue that needs to be addressed:

  • Check to see whether the battery is fully charged and operational
  • Check to see if the fuel pump relay is properly installed and operational. Additionally, inspect the connection and wiring
  • Examine the fuses for the fuel injector and electronic fuel pump
  • And Ensure that the gasoline filter in the fuel tank or engine compartment does not have any obstructions
  • Investigate whether or not there is a leak in the fuel supply that is resulting in low fuel pressure passing through the fuel rail.

How to Reset Fuel Pump Shut Off Switch

You may reset it in the same way that you would reset an electrical circuit breaker in your house by pressing the button or drawing the lever down. All current fuel-injected automobiles are equipped with an inertial fuel cutoff switch, which disables the power supply to the fuel pump if the vehicle is involved in a collision with another vehicle. As a result, it stops fuel from being pumped in the event of a fuel line failure during an accident or incident. After a car accident, you must locate the gasoline shut off switch (also known as the car inertia switch) and reset it in order to restart the engine.

The ignition switch, on the other hand, was in working order, and the engine was turning over.

Then I realized that it may be because the gasoline cut off switch had been triggered, but the problem was that I couldn’t find it!

One of these locations was behind the drawer/glove compartment on the passenger side (the right side of the vehicle on US/EU vehicles and the left hand side on UK/AUS automobiles), which was one of the most difficult to access.

Steps to Locate and Reset Fuel Cut Off Switch on Ford Fiesta (For Other Cars Keep Reading)

  • The first step is to open the glove compartment. Pull out the glove compartment by pressing hard on the left side of the compartment toward the interior area
  • A red button or a yellow rubber cover on the gadget should be sought. To activate the inertia switch, press the rubber cap button on the switch.

Emergency Fuel Shut Off Switch Location on Other Cars

On Ford, Peugeot, Volkswagen, Citroen, Vauxhall, Subaru, Renault, Toyota, and Mazda vehicles, the inertia switch is often located in one of the following two concealed locations:

  • Behind or below the glove box, and occasionally tucked under the carpeting
  • The underside of the side panel, which is adjacent to the driver’s door
  • It is located on the driver’s side of the vehicle, in the space between the footrest area and the door, and is occasionally covered under the carpet.

How to Reset a Fuel Pump Shut Off Switch

Images courtesy of Jupiterimages/Photos.com/Getty Images Many of the automobiles on the market today are equipped with gasoline pump shut-off switches. When a vehicle comes to an abrupt halt, these devices, which are effectively circuit breakers, are designed to activate the airbag control module’s inertia switch, which is located inside the airbag control module. This safety mechanism is meant to cut off the gasoline pump in the case of an accident, however it can be activated by a pothole or even by abruptly using the brakes in some circumstances.

Step 1

In your automobile, look for the inertial trigger or the airbag control module. If your owner’s handbook doesn’t specify where to check, try looking within the center console, beneath the front seats, behind the glove box, or behind the driver’s and passenger’s side kick panels, respectively. These are the trim pieces right in front of your front doors, where your foot is most likely to brush against them.

Step 2

Push the button on the inertial switch; it should be clearly labeled as the fuel pump reset button and may be a different color from the rest of the switch’s buttons. Some vehicles may need that you turn the ignition key to the on or accessory position in order to fully activate the module and restore functionality to the switch. Please go to the following step if your inertia switch does not have an external button to operate. Remove the inertia switch cover by either pulling the plastic clips away with your fingers or removing the screws that hold it in place with your screwsdriver.

Return the button or the breaker switch to its original position by pressing it or flipping it.

When your car has been subjected to a significant jolt, this mechanism prevents the electronic fuel pump from delivering gasoline to the engine. If the engine cranks but does not start after an accident, it is possible that this switch has been triggered. By the kick panel access cover, this switch is hidden beneath a flip-up cover in the front passenger’s footwell, near the kick panel. To reset the switch, perform the following steps:1. Turn the ignition to the off position. 2. Check for leaks in the gasoline distribution system.

  1. If there are no leaks visible, reset the switch by pressing the reset button all the way in.
  2. Insert the key into the ignition and turn it to the “on” position.
  3. Release the key from the on position and wait a few seconds before releasing it again.
  4. Conduct a second inspection for leaks.

Fuel Pump Cutoff Switch For Theft Prevention

Considering that older automobiles are easy to steal and that I have a strong attachment to my old Mercedes, I installed a fuel pump cutoff switch, which I tucked away beneath the dash. Equipping your vehicle with a gasoline pump cutoff switch for theft prevention is a simple but effective approach to render your vehicle unusable. To install a cutoff switch, you’ll need to do the following:

  • Insert Kill Switch, wire it in line, splice it in, and install heat shielding. Solder connections, tape up wiring, and test the Kill Switch when you have completed the above steps.

Fit A Fuel Pump Kill Switch

It is only possible to install a fuel pump type kill switch on a vehicle that has an electric fuel pump; if your vehicle is an antique with a mechanical fuel pump, you will need to consider installing a manual fuel valve in the fuel line or an ignition kill switch instead. For the sake of preventing the wiring from coming loose, which may cause the engine to stall, I’d want to solder it in place. Soldering wires together is the best method of joining them; yes, you could twist the wires together or use scotch clips, but you run the danger of them coming loose.

  1. The first step is to identify the power supply circuit that supplies electricity to the fuel pump.
  2. Then, once you’ve determined which wire is in charge of the pump circuit, you may take out the fuse and cut the wire downstream of it.
  3. Now, choose an appropriate spot for your kill switch.
  4. Make use of your creativity; your only constraints are those that you set for yourself.
  5. Now that you’ve chosen your spot and installed the switch, it’s time to get creative.
  6. Organize your wire now before cutting it to the precise length you want; in many cases, the wiring may need to be routed in an indirect manner.
  7. Install the fuse and do a test on your work; the fuel pump will buzz briefly when you turn on the power.

What You’ll Need To Fit The Kill Switch

To avoid unexpected shopping visits, here’s a shopping list to keep on hand:

  • The following items are required: Test Light/DVOM
  • Wire Strippers
  • Soldering Kit
  • Screwdrivers
  • Kill Switch
  • Black Tape
  • Copper Core Wire (about 6ft)
  • Wire Heat-shield.

Ignition Kill Switches

Another alternative is to use ignition kill switches, also known as dizzy switches, which are simple switches that are installed in the wire that runs from the distributor to the coil. Some automobiles will not have a distributor, and as a result, the right wiring may not be immediately apparent. It’s possible that you’ll require a wiring diagram on hand. Modern automobiles equipped with a computer-controlled system managed by the CAN network will not function properly with an ignition kill switch.

That’s what we term a “contemporary classic automobile.” Anyway, it will not like more wire being connected to its looms, since this may lead the computer to become confused as to what is going on in the environment.

It will consider the kill switch to be a problem and will most likely flood your computer with a slew of error codes.

Battery Kill Switches

The battery kill switch is available as an option for both older and newer vehicles. It is available in either a manual or a remote-controlled configuration, with the remote configuration clearly costing a few dollars more and requiring a little more effort to install. An efficient anti-theft solution, the battery kill switch also stops your car from short-circuiting and catching fire while in use. You’ll have to re-adjust your dash clock and radio settings every time you activate the basic kill switch because it completely shuts off the vehicle’s electrical system.

Battery kill switches are not ideal for late-model automobiles since they must be linked to a power source at all times in order to function.

Fuel Line Cut Off Valve

A mechanical solution for a mechanical gasoline pump is presented here. It’s a simple tap that goes between the petrol tank and the carburetor of your vehicle. The tap, like the kill switch, should be positioned somewhere inconspicuous; however, placing it inside the automobile is not recommended. It is possible that finding a hiding place will take longer than actually fitting it. Simple steps such as cutting the gasoline line, pushing on the valve, and securing it with clamps are all that are required to install it.

Fuel Pump Shut-Off Switch – Inertia Activated

A post-crash fire produced by pressurized gasoline sprayed from burst fuel lines is less likely to occur when our Inertia Activated Fuel Pump Shut-Off Switch is utilized. It will disconnect power to an electric fuel pump after an impact of 10 to 12 G’s* or higher*. A simple press on the top of the switch will bring the switch back to its original state. Many manufacturing automobiles are equipped with such switches as standard equipment since they are such a cost-effective safety feature to have.

The switch’s continuous load rating of 10 Amps allows it to manage the current of most electric fuel pumps (such as Facet low-pressure pumps) without any additional components.

Included are a switch, a connecting kit, and comprehensive instructions.

Each component of the kit is universally applicable to any vehicle equipped with an electronic fuel pump.

Most original equipment manufacturers (OEM) air bags are programmed to deploy in a 7 g collision, which is similar to hitting a solid wall at 15 mph or a stopped vehicle at 25 mph. Please keep in mind that the pre-wired “pigtail” lead as well as the mounting screws are no longer supplied.

After a work day with my rookie squad this past weekend, one of my fellow monkeys. team members discovered the inertial fuel pump shutting switch, which he then proceeded to turn off. Then it dawned on me: it had been 20 minutes since I had attempted to figure out what the hell I had done to the ECU/dash/gauge cluster (I was working in the front of the car at the time). Whatever the case, I started thinking about the possibility of being bumped (or bumping into someone) on the track, and it occurred to me that, should the inertial switch be tripped, it would be extremely inconvenient (and quite possibly dangerous) for me to have to go back into the trunk and press the switch down once more.

  • Additionally, this provides me with another thing that I can offer to the TCCOA.com aficionados.
  • Do you think it’s a good idea to get rid of this inertial switch?
  • Q: I realize this may sound like a silly question to those of you who are rebuilding 1950s radial engines to fit into small cars, but this is the first project vehicle we’ve undertaken, and we want to do it right the first time around.

Re: Q: Do I need an inertial fuel pump cutoff switch? Should I bypass it?

Remove the switch from the circuit and bypass it. I understand that it is not required by the standards, but it is never a bad idea to have a battery cut-off switch that the driver can reach (whether or not this necessitates the use of a second switch) just in case there is a need to disconnect power to equipment such as the fuel pump.

Re: Q: Do I need an inertial fuel pump cutoff switch? Should I bypass it?

Yes, that should be removed. Getting rear-ended and having your motor die in the middle of the race course is the last thing you want to happen. Make sure the driver has easy access to the fuel pump by installing a separate switch for it. Make certain that it is fed via the kill switch rather than straight from the battery. The gasoline pump should be shut down by both this switch and the safety kill switch. Another advantage of this approach is that it allows you to test with the fuel pump turned on and the ignition turned off, or vice versa.

We too have one in the trunk of our t-bird, but it’s not visible. I didn’t have any issues with it during our first race, but I’m going to skip it for the second one to be safe. I strongly advise you to do the same. Our Ford’s engine bay power distribution box included a 60 amp fuse that controlled both ignition circuits, so there was no need for a cutoff switch (we have 2 coil packs). With the fuse wired inline, we simply ran a line from both sides of where the fuse was linked up to the cutoff switch, with the fuse connected inline.

Re: Q: Do I need an inertial fuel pump cutoff switch? Should I bypass it?

In its stead, you may wire in a fuel pump switch, which turns the device into a fuel pump kill switch. Instead, you may just link the two wires together and let the ecu to manage the fuel pump as indicated. Generally speaking, I would avoid a gasoline pump switch that also operates the pump key. If you are unconscious and the fuel is leaking, the last thing you want is for the fuel pump to continue to operate or for you to have to remember to turn off the ignition switch. Essentially, allowing the ecu to regulate the situation is the safest course of action.

Oil pressure is also desirable, but if your engine becomes oil starved in a corner, you will also become fuel deprived unless there is a delay circuit built into the engine. A 1984 4000Q 4.2V8 driven by Killer B (as in rally). Audis are never victorious, are they?

Re: Q: Do I need an inertial fuel pump cutoff switch? Should I bypass it?

A relay might be used to control your fuel pump switch, in my opinion. Connect the relay to the ignition/key power so that the fuel pump can’t be turned on until the ignition switch is turned on as well (that way you kill the fuel pump when you kill the ign). It is not necessary to have the car running; simply turn it on. To put it another way, connect a wire from the hot side of the ignition to the bottom terminal of the fuel pump cutoff switch, then connect the other end of that wire to the proper contact on the ignition relay.

It avoids passing full voltage via switchgear that may not be capable of handling it, and it is controlled by both the fuel pump switch and the ignition switch, which is a bonus.

However, as a result of global commerce, Bosch-style 4-post relays are available for a low, low price on eBay.

Not the ECU, but the inertial switch is what I intend to override.

-g So far, I have the following gauges: * Coolant Temperature Gauge * Oil Pressure Gauge * ATF Temperature Gauge (automatic tranny so this is a concern) I added the following features: * Fan motor override (to allow me to run at full speed while the car is off) * Fuel pump cutoff (which cuts out just like the inertial sensor) * rear defroster (because it’s already there and I removed the center console it was mounted to) * Trunk release button (as mentioned above)* Gas door release button (ditto above).
