Mazda 5 2008 (58) 2.0D TS2. Strange problem. Changed low beam headlight bulb on offside. Lights working fine but when you turn the ignition key you just get a click and will not start. Battery checked on voltmeter and is fully charged.
Now sorted. My 5 year old daughter was in the car whilst I was working on it. Connections had been pulled apart under console by the pedals.
Please don't charge me £13 for sorting out my own problem.
