Thank you so much guys for your input and yes you are right about the module. The mechanic took the car for a test run after playing with the engine and it broke down on him so got an auto electrician out to check the engine and he came to the same conclusion as Roger. So once the parts arrive,the car should be good to go and I can have my car back.Thanks again for your help as I was lost on this one and my sister has a habit of just paying people to sort the problem without checking if I may be able to help.
