Reccently brought a 'P' reg 306, it ran fine for afew days with no problem. Drove to work yesterday and put in petrol has light had just come on. Drove to work fine, no probs. 12 hours later went to start and nothing. No ignition lights, no power to centre password console (That where where you input a 4-digit code) Would not start from jump leads and would not bump start. Any ideas as to what this might be?
