Thank you for that but I have found the starter may not be the problem. Basically my wife would use the car get to a destination stop turn car off. Now if she returned to the car not long after being run and try starting the car would turn over but would make a strange rattling noise. After leaving it to cool down the car would start no problem and no rattling noise.recently the car has been stood for a few weeks and went out to start it the other day and the car would turn over but make this strange rattling noise. Noticed that when turning engine off the starter would make a whining noise while disengaging so toon starter of tested and cleaned all of the leads up. Put it back on yesterday and fired straight up no problem. Tried it again later that night started fine. Wife went to it this morning won't start and making this rattling noise intermittently but the engine is turning over. Unfortunately can't pinpoint where noise is coming from either. Does anybody have any ideas what this could be. The galaxy is a 2.3 16v petrol manual. V ref. Thank you in advance
