You will need to get power to that! Will prevent starting I think!

I  just traced the main knock sensor wire all the way back to the ecu,It has no power to it from the ecu.

I am unsure if i am barking up the wrong tree with this but the car never gave me eny problems before this. Having checked/replaced near enough everything else i have nothing else to lose
