have your mechanic install a kill switch or kill switch and relay…
i don’t know how hyundai powers the fuel pumps…
on single speed fuel pumps… there is a fuel pump relay in the underhood fuse box… could be else where…
a 4 or 5 pin ISO relay… the power wire to the fuel pump is cut… the relay installed the wire from the front goes to relay pins 30 and 86… the wire to the pump goes on 87… pin 85 gets a long wire to a hidden switch… if you are crazy smart you will have that first switch not hooked to ground but to a second switch hidden in the trunk… so you can turn off… one or both to prevent the fuel pump from being powered …
if you use a 5 pin relay… you can use pin 87A to power a horn hidden inside the car…
Assuming it’s a normal transponder key, have the dealer or a locksmith reset the vehicle immobilizer and add only the keys you have on hand.
