I scan/diagnose it for posible causes and the only code that came was PO343 - fuel Pump Relay.
I replaced it and problem stoped for 2 weeks and it starts again.
I then adjusted the idle bolt n nut to make it idle very low and it worked well for about 10mile, soon as I get into trafic jarm it stops and I av to restart somany times so readjust to rave high.
I am looking to buy new relay to be sure this can solve the problem as the one I fixed earlier was a use one from another car 'cos it dificult to get new parts from ♍γ̲̣̣̥ side here..
May be spare also got spoil or that is not the actual fault. I don't know.
But try diagnose the car for posible electronic fault and see before doing somany try n error.
