I have just replaced the Head gasket on a 1.4. Went to start it and there is a buzzing noise coming from the engine bay. Have narrowed this down to a fuse in the top left hand corner of the engine bay right in front of where the driver sits. I have also noticed that the yellow code light will no longer go out. I have previously replaced the engine in this car and can remember i had the same problem when i tried to start for the first time after that but havent got the foggiest how i fixed it.:bang: The car still turns over from the starter motor so i think it is something to do with the immobilizer. By the way, when i remove the fuse, the code light goes out but car still wont start. Any solutions??
