Neutral safety switch
X3, but I'll add my latest debacle as food for thought. I was at the ready line (before the burn out box) 2 weeks ago when I tried to start the car and....nuthin....no click of the starter, nuthin. I realized that my neutral safety switch wire must have come off, but by the time I got under my hood, hooked up my jump wire (to ground the neutral safety switch on the starter relay) it was too late....The other car got a competition bye. This was after I had bought back in because I was a first round runner up...I was NOT very happy. When I got home I confirmed what had happened, the neutral safety switch wire had wiggled off the plug on the transmission.
So my fix was (thanks to my friend Matt for showing me this), I ran the neutral safety switch wire through a toggle switch on my dash, so if this ever happens again I can flip the switch from inside the car (completing the circuit) and still have a chance to go on to the next round.
