My wife has an Hyundai Accent 1.5 Diesel 2002 model. Shortly after buying it, it would not start for me when I left work. I cranked it 4 or 5 times and got nothing. I went back into my office, left it ten minutes, went back out and it started as if nothing had happened.
That was quite a few weeks ago. Yesterday my wife was out in the car and on leaving the local Tesco it would not rev. The throttle pedal did nothing. She called the RAC who came out and basically fiddled about and the car start revving again and carried on as if nothing had happened. The RAC man said that he had hadn't actually done anything to get it going again.
Does anyone have any ideas as to what's going on? While on the subject, what's the best way to change a diesel fuel filter? I've heard bad things about disturbing a diesel's fuel supply and setting up airlocks which I think changing the fuel filter is kind of going to do.
