    Inertia Fuel Shutoff



    Has anyone else had to reset their inertia fuel shutoff? My 2002 V6 automatic started dying while cruising at 45 mph. I pulled into a parking lot and it DIED!!!! Battery power was still good, the engine was trying to turn over, but that was all she wrote. My husband had a similar problem with his Ford Ranger so after trying a few things, he reset the shutoff switch and I was good to go. A little scary that this could happen though!

    Inertia Fuel Shutoff

    This may be related to the fuel pump instead. Try to check the pressure of the pump to determine if the pump is at fault. It usually happens when the tank is low on gas.

    Inertia Fuel Shutoff

    I don't know of an "inertia fuel shutoff", but I had a similar problem w/my 87 Nova. Taking extreamly hard, fast turns would cause the car to stall because all the fluids would shift. I've never seen or had this happen in a Cougar, and I take turns even harder in this.

    You could have low fluids somewhere, be it oil, powersteering, coolant...many things. Our cars only have an "emergency fuel shut-off" switch under the dash, not a reset. The Duratech engine does have a problem w/the oil pan not holding oil properly during hard cornering, but I think they fixed that and your '02 Duratech engine should reflect that change.

    How much gas did you have when this happened? Maybe check your fluids.

    Inertia Fuel Shutoff

    For the gas, I had a little bit less than a quarter of a tank. I've taken it below the red line before (I know I know) and never had a problem. That was about a year ago. It's still under warranty so I took it to the dealer and they are going to replace the fuel pump. Thanks for all of the help!

    Inertia Fuel Shutoff

    The Inertia Fuel Shutoff I believe you are discussing is a inertia switch that cuts-off fuel from the gas tank in case of a rear end accident, to prevent the discharge of fuel outside the car should the pump keep working. The problem here probably is the fuel pump, have it checked out. My previous car (an I-4 Probe) wouldn't start after a minor rear-end accident until I reset the cut-out switch. The reset switch is in the back of the car. Some vehicles, especially diesel and hybred/electric cars have cut-off switches for the fuel or electricty that are to be used in case of an accident or where the vehicle keeps running due to an electrical or fuel fault.
