My kill switch cuts the circuit through the fuel injector fuse. I use the switch about 110 to 150 times per week, and it sets the CEL about 2 or 3 times per week.

I get one of two codes. One is for the fuel injectors, the other is for the gas gauge sending unit.

get a cheap code scanner ultra or scan gauge. clear the codes before taking it to the dealer.

Sincerely, thank you everyone for the help. Each day off it rains, and I do not attempt to develop a plan. Since my tank of extreme EOC went awfully bad, I am not EOCing right now. After my oil change and FE comes back up, I may resume it, and work on the switch.

As of now, EOC switch is on pause. I will update on any future info.

I have recently been actively EOCing, but am so tired of flipping they key-and missing out on miles I am traveling, but not getting credit for. So I installed a kill switch, specifically for a fuse- but it did not work. I pulled the fuse, and the car kept running.

THis is the user manual, page 231 starts fuse labels.
http://www.motorcraftservice.com/pub.../12musog2e.pdf

If anyone has any suggestions or ideas, please let me know. I have looked, but I have to buy new fuses for it, so I do not accidentally ruin my current fuse, and walk to get more. SO, I want to buy them first, then do the test.

Thank you in advance for the continued support.

I (we) cannot get at the manual. can you copy it into a post?

see if the manual lists the wire going to the fuel injectors, then put the relay into that wire. thats what I did as most newer cars have several things on the same fuse that runs the injectors. Things like fuel pump (you can burn it out with over cycling) so try to find the wires to the injectors. there might be one in the fuse panel. my bothers kia had a separate one but my matrix did not.

I tried a few methods, but this was the best I could do. The only fuel injector fuse is only in effect on the Shelby, unfortunately. I was trying to avoid using a relay, I set it up to replace just a mini fuse. I was tinking the PATS might be the next best, but that may only stop starting-not ignition in the engine. I can't refind the forum and post that gave me my first attempt.

have you tried this one:
15A** Fuel injectors (Shelby only)

or :
PCM vehicle power 4 – ignition coil Fuel pump relay? the issue with this one is that it cuts the fuel pump as well, this can lead to a long restart wait as fuel pressure is built back up. I would try to find the split to the fuel injectors alone and put the relay in there.

I THINK that a momentary contact kill switch would work here. Hold the switch long enough for the engine to coast to a stop, then release. Once released, the fuel pump should restart and pressurize the fuel system so everything is ready to go when bump started.

100% Successful so far. Only used about five times at this point, but it's working flawlessly.

Engine kill switch - EcoModder
The Shelby only is only for the Shelby...now I wouldn't mind a supercharged 5.8, but it's a little more than my six lol

I did get it working with another fuse. At this point, it is working great. My only concern is it shifting out of the spot, and the connections not being secure.

Each use sets off my UG, but no codes yet. As soon as I flip the switch back everything goes to normal, no CEL yet.
