Does anyone know where the main relay switch and/or the fuel pump relay is for a 93 civic lx? The fuel pump will only come on some times and when I first turn the key I hear clicking sounds but cant find out where they are coming from. I Put a new Fuel pump in and it still only comes on sometimes. So now I think it is the main relay or fuel pump relay. Any help would be much appreciated.

 

I belive on civic the fuel pump relay is wired into the main relay...a friends integra did the same exact thing....he touched the realy while the key was in acc. heard the fuel pump prime and it would start right up...it sould be under the dash on the left hand side of the steering wheel...i believe its held up by a 10mm bolt and is a brown box...hope this helps

 

Thanks

 

its actually a grey box with a red-ish connector. yes 1 10mm bolt. right near the hood release.
