A few days ago my V reg 306 had to be jump started, it started fine and ran fine for a further five days. The car then wouldn't start after not being started for around 12 hours. Aswell as the car not starting, the central locking, trip meter, harzard light button, stereo and fuel/speed gauge and ECU etc there was no problem found and the car still does not start. Does any one have any ideas about this??????
