Can any one please help give some advise on my micra.It was running fine one day the next died. Breakdown guy added fuel to air intake and car ran for 10 seconds then stopped. Mobile mechanic called and carried out diagnostic and produced fault codes P0003e and p0007e. Fuel regulator volume control and fuel shut off valve. He changed the fuel reg as this seemed to be the indicator as there is good sparks at plugs.( on the fuel rail) but with no luck. Should I now spend another £ 130 plus on fuel shut off (does any body know location of this) . Don't know if its worth that much more money?

Would appreciate some advice. Thanks.in advance.
