#207058 well today i was going to install a kill switch on my car, now it wont start here are the steps i did.

1)I started the car to move it to the garage
2)I cut the yellow/green with silver dots wire from the full pump
2) I tried starting the car with the wire cut it didnt work
3) I put connect back the wire it did start.
Now here is were i think i fucked up lol
4) I was connecting the extra wire to the switch.( I wasn't sure were the wire went to the switch so i move them around trying to see witch was were the correct ones to turn on and off the switch, I'm not sure but i think the touch.
5)since the car wouldn't start i but back the wire (yellow/green with silver dots) so i didn't still the switch. the car wont start now
6) I check the full pump and it does make noise when i turn on the ignition, and it does have voltage.

What would be the problem the main relay or the ECU ? tomorrow im going to get a new relay hopefully thats the problem but if not do you guys have any ideas of what the problem might be? all the fuse are good by the way.

#207265 First and foremost, a fuel kill switch will do absolutely nothing to prevent theft. Thieves caught on to it instantly several years ago when it became popular in the Honda scene. Do a main relay kill switch instead.

Secondly, if your fuel pump primes and has voltage, then the no-start issue is not related to your kill switch. Also, your main relay is good. I see no reason to suspect the ECU.

How did you test for voltage? What was the voltage reading?

There are many different ways a car will not start. You need to go into much more detail about exactly what that means.

Also, please work on your writing. I don't know what "I think the touch", "I put connect back" or "so I didn't still the switch" means. If you're not going to put some effort into communicating clearly, no one is going to make the effort of helping you.

btw it does not matter which wire connects to which pin on a switch. A switch is simply a convenient way of cutting and reconnecting a wire.
