GM and many others uses the oil pressure switch. Other car makers use different safety strategies to shut off the fuel pump. Why don’t other car makers use an inertial fuel pump cutoff switch? This makes far more sense since the SRS is designed to activate the seat belt tensioning system and airbags when a vehicle impact force reaches a set level. They still employ an inertial fuel cutoff switch, only now it’s incorporated into the supplemental restraint system. Just because you can’t find the switch doesn’t mean Ford stopped using it. Why did Ford stop using the inertial fuel cutoff switch? Once you find the inertial fuel cutoff switch, resetting is as simple as pushing the red reset button. In later years, Ford moved the switch to either the right or left kick panels in the passenger compartment. 1-5 of 5 Results Filter Sort by Price Duralast Fuel Pump Inertia Switch SW4177 Part SW4179 Limited-Lifetime Warranty Check if this fits your vehicle.

IDEAL ELECTRIC COMPANY - formerly known as Hyundai Ideal Electric: MANUFACTURING SPECIALTY ELECTRIC MOTORS GENERATORS CONDENSERS POWER SYSTEMS & CONTROLS. ![]() Most Ford fuel cutoff switches incorporate a manual reset button that moves the steel ball back into place against the magnet, thus resetting the system. How do you reset a fuel pump cutoff switch? Simply put, they were not very accurate in detecting the difference between an impact and a bump. Unfortunately, the older switches could also activate on rough roads or when hitting a deep pothole. The engine would crank but would not fire up because it had no fuel. You would return to your car and try to start it, not knowing that it had been bumped. This happened quite often in parking lots if another vehicle as much as touched your car while maneuvering. The early inertial fuel cutoff switches could activate simply by bumping the vehicles. What would make the fuel cutoff switch stop fuel? However, when the vehicle encountered an impact strong enough to move the ball away from the magnet, the ball would move off the magnet, disrupting electrical flow to the pump. While held by the magnet, the ball touched electrical contacts and maintained power to the fuel pump. ![]() ![]() Find out more about our advertising opportunities.The early switches contained a gold plated steel ball that’s held in place by a magnet.
