hi everybody im new here, i have a x type 2.0 diesel i was on my way home from work and the engine just cut out then would not start, the RAC came out checked it and said the fault was with the fuel pump, and i would have to take it to a garage. he then hitched me up and took me home. i was wondering if anyone had any ideas of what could be the problem. a friend said it sounds like an electrical fault, i would be grateful of any help
