hello everyone, my 90spec mfi rs turbo for some reason will run without the fuse in to control the fuel pump, but with the fuse in I'm not getting a spark it will only fire without this fuse in, I'm also getting a problem with my headlights as well at the same time of this happening, does anyone have any idea if this is down to a faulty fuse board or something else?? Would really appreciate the help and thankyou to anyone that does!!

 

could be a short somewere, trace all relevant wires and check

 

It is difficult with such a strange issue, perhaps try removing the box and visually inspect to see if anything amiss.
