Where is the inertia switch located?
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.
How do you turn off an inertia switch?
The inertia switch was reset by simply pushing the red button on the switch. The switch could also be manually pushed to turn off the fuel pump, which worked nice for turning off the fuel pump when servicing the fuel system.
How do you know if an inertia switch is tripped?
if it tripped,then the button will pop up and all you need to do is push it back down until it clicks/stays down. it’s rare for the inertia switch to fail,but possible.
What does the inertia switch look like?
On the top of the inertia switch is a red button. With the inertia switch in the open position, the red button is raised up. It is not supplying power to the fuel pump in this position. When the reset button is pushed in (or down), then the inertia switch will let the voltage flow to the fuel pump.
What causes inertia switch trips?
The design of the fuel pump inertia switch causes it to turn off the fuel pump if a vehicle is involved in an accident. However, in certain incidents such as a blown tire or hitting a pothole in the road, the switch has the potential to trip. A sudden stop or change in direction activates the switch.
How do I know if my fuel pump fuse is bad?
Here are the symptoms of a bad or failing fuel pump relay
- Engine stalls. One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls.
- Engine does not start. Another symptom of a faulty fuel pump relay is an engine that does not start.
- No noise from the fuel pump.
How do I reset my fuel shut off switch?
RESETTING THE 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.
- If no leakage and/or odor is apparent, reset the switch by pushing the reset button on the top of the switch.
How do I reset my fuel pump shut off switch?
How to Reset a Fuel Pump Shut Off Switch
- Locate your car’s inertial trigger or airbag control module.
- 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.
Can an inertia switch reset itself?
A good inertia switch should trip completely on a collision only(sudden stop or airbag deployment), so engine wouldn’t restart without a reset. And a good switch wouldn’t trip by being towed or hitting a bump, nor reset itself, so you could have a bad switch.
What would make a fuel pump not turn on?
If either due to a faulty crank sensor, or ecu, the crank sensor signal is not being read, the ignition and fuel pump systems will not power up. Also, a faulty ignition module can create the same issue. Check for signals from the crank sensor and other sensors.
