im a real noob when it comes to cars

anyways. . .what is the noise that comes on when before you start a manual civic? its like a humming noise when the key is in the on position, and what is it. I am asking this question because when i moved my car last night a wire was sticking out from under my dash and i accidentally stepped on it and disconnected it. My car still starts, but no longer makes that sound. I see the end of the wire, but i have no idea were to plug it to, the wire said main gauge 18 or something like that. Any help would be great

 

well the noise you heard when starting is your fuel pump...on not hearing anymore..got me

 

yea im not hearing it anymore cuz i disconnected the wire, and i dont know where to connect it back to. If i power the wire straight to the battery i hear that noise again. . .

 

Untill someone more knowedgeable comes along, I suggest this. Get a freind and have him touches the wire to the battery listen to where its coming from. It should come from the fuel pump. Not sure why that wire would be under your dash though. The only thing I hear is my fuel pump gettin ready to feed the beast.

 

yea i did touch the wire to the battery and the fuel pump was sounding again, but where do i hook this wire up?

 

You said your car still starts though? It goes to your main relay.
