   My 16v saxo is badly over fueling i can put the fuel return pipe into an empty petrol can an start it and within 5 minutes the can will be full, it wont idle properly and sounds like a scooby turbo, it will rev but not all the time and its slow when it does rev. Can anybody give me any ideas. The sensors i have replaced so far are:
   engine coolant temp
   crank sensor
   lambda x2
   ICV
   TPS
   air temp sensor
   map sensor
   ecu
   throttle body
   coil pack
   I have checked the injectors spray. Somebody please please help me out on this one.

   Don't really know what to look at next tbh, perhaps a fault at the actual fuel pump?

   How are the fuel lines plumbed in?
   
   How is the return plumbed in?
   
   What Ecu you running?
   
   I feel your problem lies with one of the above.

   Standard fuel pipe going to the rail and another pipe plumped in from the rail straight back to the fuel pump and im running a unlocked 16v ecu.

   Something must be telling the ecu it needs more fuel, can the fuel pump cause it by pumping to much because its fairly loud.
