Fuel pump wire for kill switch

Why are you doing that the car has an immobilizer?

Impossible to hot wire. Unless someone has access to your car with the fob in that case I would not go anywhere near the fuel pump I would kill the ignition.

For the ignition I would find a same size fuse as the ignition fuse only with a blown filament and solder 2 wires across it. One on each end of the fuse than connect a switch to those wires.

No wires or harness cut want to restore it just plug a good fuse back in.

Just don't ever try to start it because it will throw a code that you will need an obd device to clear it.

It wont hurt anything it will just throw an engine wont start code. Which may be a good thing if for instance you have a teenager that's driving your car will your sleeping (like I did lol). If he goes to start it the car wont start and it will throw a code. You get in next morning and see the code he's busted.

Btw this no engine start code will be thrown no matter how you disable the car gas or otherwise.No matter how the engine is disabled if the engine cant start when you try to make the car ready it will throw a code.

or just buy a club lol.....

 

I have no idea what your talking about and regret replying.

 

I think what you are saying is you already have some kind of theft prevention gizmo and it has two outputs, and you're looking for a good place to connect the one that (in some other car) would go to the starter.

So I guess there's nothing that makes the fuel pump a bad idea for that. You might just have to look closely at what kind of output your gizmo has (high going? low going? dry contact?) and take a look at the car's wiring diagram:

and figure out how you want to interface the two.

 

Without boring you with necessary details... The Prius is not a conventional design. It's a tightly integrated system. It has no starter motor. If that's news to you, I suggest that you discontinue your efforts. It is also a modern design, which means that it runs tests on the fuel system after you park the car. Mess with that and you might fail your next emissions test. You will also have a CIL glaring at you every day.

The last time someone made a similar inquiry they were trying to steal a car and needed to defeat the aftermarket kill switch. I'd give it up if I were you. The Prius is seldom hotwired in most areas. It's much more likely to have it's cat ripped off while sitting in the owner's driveway.

 

It seemed to me that the OP realizes the car hasn't got a starter, and just has an anti-theft gizmo with an output that says "connect this to your starter" and wonders about another useful way to connect it.

The car does a test of the evaporative emission control system a few hours after parking (if Gen 4 is like Gen 3, which I have), but not one that involves the fuel pump.

 

My mistake. I thought that the test included pressurizing the fuel line.

 

You might give the forum more of a chance. As toxic internet forums go, we might be less so than many.

Sometimes it's kind of down to the luck of what your first question happens to be and who happens to answer first.
