I was installing a kill switch in my 07 TL and now my car won’t start. I disconnected all harnesses from the fuse box to get to the fuel relay power wire and splice a switch into it.

when I reconnected all the harnesses from the fuse box and tried to start the car it wouldn’t start.

All dash warning lights are on including the immobilizer light. the car won’t turn off unless I disconnect the battery

also nothing happens when I twist the key in the ignition and it won’t unlock any doors

the power seats don’t work the trunk unlock doesn’t work

the head lights and brake lights work as well as the wipers and wiper washer

I’m not sure if this is the immobilizer system preventing me from starting the car because usually the key in the ignition would still allow the car to be turned off but now it does nothing

I also have a long list of b codes displayed on the dash but all the harnesses are connected

I inspected all the wires i disconnected and I didnt see any rips. And I double checked to make sure all clicked in correctly

im at a loss can anyone tell me if this is an electrical issue or an immobilizer/ security system issue

Did you disconnect the battery before doing work? Have you checked all of your fuses? Did you put any fuses in any blank spots thinking they were missing?

Did you cut or damage any other wires when splicing in the switch? You could have fried the MICU/fusebox with all the B-codes listed. It's all a guessing game since we are online and can't see any of the work performed.

I did disconnect the battery before working. I just checked all the fuses and all of them had continuity. I did not put any fuses in a blank spot.

I only cut the fuel pump wire and I checked all the other wires to make sure they were not ripped, all of them looked fine.

This is what I’m looking at right now. The key won’t turn the car on or off

Even when I manually close the door and lock it the car stays on. It will only stay off if I disconnect the battery. The key in the ignition has no effect on the car whatsoever at the moment

Is your wiring for your kill switch keeping the ignition/accessory power bridged so its always on?

Have you tried just methodically un-doing what you've done?

XOGhost

Yes I’ve actually disconnected the kill switch and just reconnected the fuel wire back to itself like normal

XOGhost

It’s still the same as before and won’t turn off or start. I have also disconnected and reconnected every plug to the fuse box

I also spoke to an Acura technician over the phone, and they said that the fuel wire should not cause the car to stay on. If anything, I should at least be able to hear the starter clicking but I got nothing.
Then again, I'm not an electrician and the technician did not have the car in front of him to diagnose it so I could have missed something.
I honestly think I'm just going to pay for a legit tow truck. I'll let you guys know what the tech at Acura says.
