Heyyah guys im 16 years old and just bought my first car off a mate for £200. A Ford Fiesta Zetec 1999 MK4 16v - as per the price i have some problems.....

1. The driver side door is very temperamental and will not unlock?

2. My fuel gauge does not change even if i fill the car up. I first got in the car and turned it on to see the that needle was at empty and the orange light had appeared. After filling £10 into the tank this did not change....fuel sender unit? I hear it is placed under the back seat, how do i fix this problem?

3. The break pads and break disc needs changing. I can find these cheap on the internet but how do i change them? Are there any videos about? or....

I have no quals in motor vehicle and have never even changed a wheel...I will need a lot of help. I would love to get into motor vehicle but need a push in the right direction :)

Get yourself a http://www.haynes.co.uk/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&storeId=10001&productId=12921&langId=-1 Haynes Manual which will show you how to carry out the tasks you describe. You can usually pick them up on eBay second hand if you don't want a new one.
