my Citroen c8 doesn’t start?
With a broken timing belt you will have: bent valves damaged pistons possibly bent con rods Or just a useless timing belt. Do not try cranking the motor over (might lead to all issues mentioned above). Take it to a capable garage!
Insert your car’s key into the ignition switch and turn clockwise until you hear sounds from the engine bay.
If you have a keyless push button ignition it requires you press on the brake to start. There’s a brake pedal switch that performs this function which is a common problem and quick repair.
