My 1996 diesel peugeot 205 has plenty of diesel in the tank and has a battery that has plenty of juice. However, when I go to start the car absolutely nothing happens. The engine does not turn over what so ever and all the lights on the dash go out. This problem happens only sporadically and completely randomly with seemingly no warning. Quite often after leaving the car for an hour or so the car will be able to start again. However, on the latest occasion the car does not want to start no matter how long I leave it. I would be really grateful if someone might be able to give me an idea of what could be wrong.
