My mechanic advised that my timing belt is due to be changed, he changed it and started the car, it starts normally, however, after coupling back all he removed while trying to fix the belt, the refused to start. it gives sound as if it will start but never did. Since then, he has removed and reset the belt,control the injector system, check the fuel pump for faults and even sought the service of an electrician and nothing was found wrong, but the car will not start. Am confused
