Fuel Pump Relay Fuse #

Just looking for some extra security precautions...

If I go down to the 🇺🇲 with the truck and go to a mall/gym for a couple hours ...
I don't want to risk losing my truck.
It's old but still in great shape.
It's a 2000 4.6 V8 F150

Is it bad for the electrical system if I pull the fuel pump relay fuse before parking it ?

I mean, it's both costly/takes time to have a kill switch installed.
The club is useless ....unless I use a tire boot.??

I'm thinking just pull the fuse ...

What fuse number is it ?

Also the outside temperature digital display stopped working all of a sudden...
Is it a fuse or something else that burned out ?

Your truck (presumably) already has the PATS system. No one is going to start the engine without the pre-programmed key.

I suspect you're over-thinking this....But, since you asked, it's fuse F10 in the under hood fuse box.

So to be clear ...

It has the PATS system. I see the "Theft" light on the dash constantly blinking when vehicle is in park and engine turned off.
I don't use the remote keyless entry for it.


If I have only the key on me or better yet in a Faraday pouch, am I even better off(safety wise) ?

If I go down to the States and I'm in a gym for a couple hours or mall I don't want my truck getting stolen in the lot.

I also read that an OBD2 lock is a must.
That's a vulnerable area of the vehicle for car thieves to exploit.

You're WAY too obsessed about this....

Just lock the doors and put the key in your pocket then go do whatever you need to do.
