Forget about what the fault codes state, provide all the fault codes for review and comment. Most people TOTALLY misunderstand what the codes mean. If a sensors is mentioned, RARELY is the sensor the problem!

Withholding information will not help you. People here likely are more experienced than you and your local mechanics.

My guess is all your codes are misfires, lean codes, mixture control, this is NORMAL because you have vacuum leaks, plastic and rubber under the hood needs to be replaced.

When you removed the rear seat, did you remove the fuel pump access cover? If not, you will not be able to see the fuel line and top of the tank. There are 3-4 screws/nuts to remove a round access panel with wires going through it that is about 8"/20 cm in diameter.



Take a picture of what you were looking at.

My guess is all your codes are misfires, lean codes, mixture control, this is NORMAL because you have vacuum leaks, plastic and rubber under the hood needs to be replaced.

Cold start problems.

Just want to say thanks for everyones comments. It was the fuel pump. The previous owner had a second hand pump fitted. So I fitted a brand new one, it's a different car!

Must have purchased the car from a Scottsman!
