After my car died i thought it was the coil/module, it works brilliantly, ill explain the power tower part as i think its genius

we dont have the power tower available in the UK, so i got an old spark plu, and took a hammer to the white part, then chopped the top of the metal rod off, leaving around 1.5CM (half inch) then i used a tap and die to make a thread on it, then figured a nut from the MSD blaster fitted it, so drilled the inside big enough to get the nut in, then screwed the top part of the spark plug id threaded into the nut..
so, after having a perfectly working ignition, i figured it must be the fuel pump...and it was, the wire had rubbed against the car shell shorting it out and melting it, i traced the wire all the way back to a relay in the centre console, then worked out it was the signal to turn the relay on to turn the fuel pump on, so does anyone know what wire from where is the signal to turn on the fuel pump??
thanks all
