kay so.
Today me and the homie aaron decided to install a kill switch. we used the ignition wire to the fuel pump and spliced into it with the kill switch .. Mission accomplished. or so i thought. We give it a test, stsrt the car and turn the switch off.C ar stops running, Perfect! Job done . Turn the switch back on fuel pump wont kick on. so where like WTF so i take the kill switch off and just resoldered the wire so everything should be good right? Wrong the fuel pump still wont turn on and the car was always pulling a #6 code on the ecu but not anymore. Ive spent 3 hours alone trying to make her run with 4 people that are mechanincs and myself and have no idea whats wrong

 

sounds like you burned something up, maybe a short somewhere. i had a kill switch on my ef, installed it by connecting the ground to the sending unit, but i never used the fuel pump wires. why would you hook it up to the fuel pump?

take off the killswitch and see if it will turn on

 

Run a straight 12 to the yellow wire at fuel pump if the car starts then, check fuses, re solder main relay soldering points. or check for bad connection/fried wires.

 

Check fuse fuse #14 under the steering column. It is labeled "Alternator Solenoid" but it also feeds the fuel sending unit.

 

i ran a strait 12 nothing.. ill check that fuse but im worried it could be the ecu :/

 

one time kill switch. not sure what you did, but check your fuses. does the ecu flash at all?

btw, i used a relay on my kill switch and it's powered by the fuel pump wires...works great

 

I think there is some electronic failure. I am sure it is the only problem. Get it checked by some professional properly.
