hi folks can anyone tell me where best to start on said subject ,as when parked on incline 406 hdi 2002 75k on clock ,refuses to start from cold unless using primer bulb (siemens sytem)
checked so far ;
fuel filter and housing
renewed priming bulb and housing and associated pipes that push fit
there is what i can see a red sensor on right hand side of fuel rail with fuel line coming off it where the bubbles seem to be coming from
air bubbles in fuel line
