Due to the recent SUA, I would like to install an emergency switch on the dash board in order to cut off the fuel pump in case of emergency for my 2010 Corolla.
In case of emergency with unintended "wide open throttle", I could switch off the fuel pump. The car could be coached to a rest safely with the normal function of the brake and steering.
It is not necessary to shift to Neutral. Then the non-powered engine will be moved by the motion of the wheels and will still create vacuum to assist the brake. The electrical powered steering will still work as normal because it is not switched off.
In fact, it could still be driven carefully with great caution by switching the fuel pump ON and OFF to move the car in the emergency situation to a safer place. But it will be a very uncomfortable drive because it is ON-OFF engine power.
Wonder if any one could locate the circuit diagram for the fuel pump.

Wouldn't it be easier to shift to neutral IF & only IF SUA were to happen to you, which odds are, it won't? Just a thought.

If it is shifted to Neutral, the engine could race to or exceed its max rpm and it may be damaged in a short time.
Cutting off the fuel and not shifting to Neutral will allow the car coaching to a safe place with the help of normal brake and steering.
Fuel cut-off switch is particular useful for "Smart Key" car, because it takes at least 3 seconds for the car to turn OFF in case of emergency.
IMO, all cars with ECU throttle (drive-by-wire) should have a Fuel Cut-off switch.
If it is really the case, Toyota is responsible for the engine damage, if I am in that situation, first thing to think about is my personal safety, not the engine. And the rev limiter will somehow protect your engine from over revving as well.

yeah dude... let ur engine rev as high as it wants... as long as ur not in gear going with it....
your safety > engine damage

Toyota would definately be reliable for your engine damage if that was to happen. Personally I would shift to neutral brake and bring to a stop if the engine is damaged after that ohwell I'd still be alive.

Which do you think would provide a better braking/control in case of WOT:
a) The car in Neutral or
b) The car in Gear/Drive with the fuel cut-off?
I would prefer (b).
I like your idea....at this point in time however, I do not think I would be modding my Corolla with anything that they could try to lay blame on! Just mho...Good thought though and keep us posted please!
I hate to continue the tirade of shootdowns, but I also think this is a ridiculous precaution. Its like wearing a life jacket when you drive because of the chance you could crash into a lake. Sure, might rather have one if put in that situation, but I could also just swim...
I think the fear-mongering hands of the media have grasped your mind. It is still an intelligent idea, but perhaps misplaced enthusiasm?

Okay....
Put it in neutral, engine damage due to over revving = Toyota covers it.
Putting a fuel shut off, touch wood if anything happened to the car = You are letting Toyota to take use of the excuse to not cover the damage since your mod has direct cause of the problem.
So at the end of the day......who is smarter...haha~!
I agree it is better to kill the fuel pump. Because everytime I went to the dealer for warranty work it was a hassle to convince the dealer the problem was under warranty then I usually come out with a bill to pay.
Letting the engine rev up hoping the rev limiter will kill the engine may work but if the engine blows now Toyota may have replace the motor and you have to convince them it is under warranty. Then if they do the work then your weeks without a car. Kill switch is my choice. Just remove if you have to bring in the car for dealer work, they may void the warranty
On my Toy truck I put a kill switch in the ECU circuit from the fuse in the fuse box to kill the motor, had no problems with it it, worked as my anti-theft device.
SORRY BUT I DO NOT TRUST THE DEALER. Have a BAD track record with them.

But we are talking about a recall related problem here.....so they are gonna cover it, you don't have to argue with them for the bill~!
