Petrol pump trouble

[Sdoc]

Hi, my petrol pump wasn't working properly all the time, was told it was sticking. I've replaced the pump but now my car won't start at all an the petrol gauge bounces from empty to full 3 times the stats on empty. Any help would be great

Checked you've fitted everything correctly? is the replacement pump used aswell?

Yeh the replacement is used too. Just wanted to make sure there wasn't something simple I've done wrong before taking it back for another one. Cheers
