Do all cars have inertia switches?
All modern fuel injection cars are equipped with an inertial fuel cut off switch that shuts off the power supply for the fuel pump if the vehicle is in a collision. Thus, it prevents fuel from being pumped in case of fuel line damage during an accident.
Where is the inertia switch?
The inertia switch is located behind the trim on the left-hand side of the vehicle, forward of the front door post, below the fascia. A finger access hole in the trim allows the driver to reset the switch.
Do Fords still have inertia switches?
The inertia switch is a safety item incorporated by Ford in the fuel system of its vehicles. The only time the inertia switch should trip is during a collision. However, there are other occurrences that can trip an inertia switch, such as a blown tire or simply hitting a pothole in the road.
What causes inertia switch trips?

What is an inertia switch do?
The switch is called an inertia switch and is designed to shut off the fuel pump supplying gasoline to the fuel injection system in an accident. The purpose is to prevent the electric fuel pump from continuing to pump explosive gasoline after an accident that may have resulted in a fuel-system leak.
Why is gas not pumping into my car?
”The most common reason why your fuel tank is not filling up is because you have a clogged or a faulty evaporative emissions control system (EVAP). The EVAP is designed to collect and store the fuel vapors from the fuel tank and move them to the intake manifold for combustion.
Why is my car not registering fuel?
An inaccurate fuel tank reading is most commonly caused by the sending system which reads the fuel tank level and sends the reading to the gauge. Issues can also stem from a bad gauge, blown fuses, or corroded wiring. You can self-test all of these parts at home with a few tools.
Is there a fuse for fuel pump?

What can cause a fuel pump to not get power?
In most of the cases, it is either a bad fuel pump relay or blown up fuel pump fuse which leads to fuel pump not getting power issue. But in some cases damaged fuel pump wiring, connections or a bad ground path in circuit are also common causes for no power to fuel pump.
How do you fix a fuel pump without replacing it?
How to fix a fuel pump without replacing it?
How do you diagnose a fuel system problem?
A fuel system should be carefully tested for pressure, volume, and electrical integrity before condemning the fuel pump. Often the first step in diagnosing a faulty fuel system is to simply listen. Turn the ignition key to the run position and carefully listen for a slight humming sound coming from the fuel tank.
How much does it cost to have a fuel pump replaced?
The average cost for a fuel pump replacement is , depending on vehicle and age. Labor costs are estimated between $124 and $260, while parts are priced between $95 and $854. Estimates do not include taxes and fees.
Can a bad battery cause fuel pump problems?
The fuel pump can run slower if the battery is low. This causes low fuel pressure and a lean fuel condition. A low battery can prevent one or more injectors from opening, which can cause lean misfire and/or hard starting.
Do Honda Civics have inertia switch?
The inertia switch is a device which in the event of a collision cuts off the power supply to the fuel pump to exclude any risk of fire; on the Civic this switch is located under the dashboard, on the driver’s side and can be reached by removing the side cap.
