Expert:  Kevin replied 2 years ago.
Right just to clarify. Does the car run when fuel gauge is working
Customer: replied 2 years ago.

YES,THERE IS A FAULT THAT JUST SHUTS DOWN THE FUEL GUAGE WHICH CAUSES THE ENGINE TO SHUT DOWN ALSO

Expert:  Kevin replied 2 years ago.
Right the first thing you need to do is lift rear seat up and underneath you will find a black circular cover under cover is fuel pump and sender unit . When gauge has failed firstly try tapping on top of unit to see if gauge comes back to life as I suspect u have a pump unit failing . Do you have a multimeter

I DONT HAVE A MULTIMETER,AND HAVE TRIED TAPPING THE FUEL PUMP

Expert:  Kevin replied 2 years ago.
Without multimeter I am unable to guide you further we need to make sure you have a feed to pump when the car doesn't start
Customer: replied 2 years ago.

THERE IS FIVE WIRES GOING TO THE PUMP,BUT ONLY ONE IS LIVE
