So i have a 62 plate 5455 been running fine just been struggling to start once stopped weather its hot or cold, untill sunday morning when it called time and won t fire up. Have put the pc to it and no faults coming up all we have as a problem at the moment is the hand priming pump isn t working so have a new one on order and are going to change the filters just as a start. Question is what else can i check to sort this issue, at the moment when you turn the ignition key on i m not hearing the the click from the injector pump but am told if there s no preasure in the line there s a sensor that will cut that off also. help!
