Thanks for positive suggestions. Don't hear fuel pump prime but then I never have noticed fuel pump noise. Ignition system and dashboard lights are totally dead when problem occurs. Just when I am about to call breakdown recovery, I turn key and everything starts normally and all is OK for a day or maybe two -before it reoccurs. When ignition switch has been replaced, then I am OK again for maybe 1-2 years before it starts again!!! i.e. When I am totally offguard, I insert the key and find the system dead - no dashboard "ignition" lights -although central locking and car lights working normally . Wny does replacement of ignition switch solve problem for 1-2 years???
