Hi there pal, Right, this could be a little tricky if you don't know much about cars so lets get you as far forward as possible by confiming a few things............... You say you have obtained a replacement canister from a scrappy. Does it have the purge valve all connected on the top? If you look at it you will see what it should look like and see where its broken off on the one on your car.If so you will need to reconnect the pipes to and from the canister when fitted.You will also notice an electrical two way socket coming off the top at 90 degrees.The two way plug on the vehicle wiring needs to plug into this socket to complete the electrical connection. You will notice this on the photos you have provided. The plug (which is the one with two wires attached)needs to be removed from the broken off part and plugged into the socket of the replacement cannister. Going back, did you notice the car had the yellow engine warning light on when you purchased the car? Some people have a very NASTY habit of stripping the clocks down and putting black stickers over the warning lights so you don't see them leaving you unaware of a problem underneath. Only when you connect a diagnostic reader do you reveal the trick. Its a nasty surprise for the unsuspecting car buyer and unfortunately happens a lot nowadays. All the lights should light up on your clocks then go out when you start the car to show that the system is clear of faults. Its a bit like the car performs a self test on all systems when the ignition is on and when you start the car all systems that are healthy are indicated by the lights going out. If there is a fault then a light would stay on to warn you that there is a problem. YOUR CAR SHOULD HAVE THIS YELLOW ENGINE BLOCK SHAPED LIGHT 'ON'. Let me reassure you that this is not a major problem, this light will clear when your canister is installed. So, in short mate, confirm that the yellow light is on on the clocks and that the replacement canister has the purge valve attached. We take it from there later so i get an understanding in more detail of the problem. I know you don't know much about cars and that this may be a little too technical but i give the technical detail like this so others on the forum can use this info to help them too!!!!
