Hello, I've got a pug 205 xs 1.4 1989 for two days now. It's a great car...but since today the engine won't start. However I can turn the lights on. But when I want to start, I only hear a click-sound (?the starter?) and then it's quite again. The engine doesn't even crank. And the strangest thing is that sometimes suddenly the engine starts.... Maybe the battery is too old?? The starter defect?? Any ideas?? Please oh please help me... David
