well i finally bit the bullet and decided to remove my fuel pump four hours of blood sweat and swearing,the pump was finally off.being the sort of persbod i am i thought i would open the pump up and take a look inside,just to see if i could find anything obviously wrong.went a bit far on the strip down but could not find anything wrong,no wear or tear.so i only hope that it is something electrical like the resistors or something.i have another pump that i sourced from nippon auto spares,i only hope that when this pump is fitted that it solves the problem,otherwise its gonna end in tears.this is what i found not a lot really.
