How can i Fix my fuel problem Vauxhall Zafira?

I assume this is a diesel.
You probably have a leaky fuel return hose (also known as leak off pipes). This lets air in to the system and the fuel drains back under gravity.
The good news is it's a cheap and easy repair, very DIY-able if you are a bit handy.
I cant give specific instructions as you have not given the engine code etc.
