Hi Guys

Ive had my turbo'd bonus running, but it wouldnt idle and took ages to start.. So checked all my breather hoses and found a couple werent tight at all(rocker cover ones) So used some jubilees instead and went to start her tonight. It struck up straight away and began to idle then just cut out. Turns out that the brand new fuel pump(from Auto Specialists) has stopped working? It just makes a slight thud noise now. So, to start with ive made sure it isnt the pump itself-I attached the minus terminal to the minus on a battery and then put a wire on the positive terminal of the pump-when i go to put this wire then to the positive terminal on the battery, its sparks like hell and no noise from the pump-does this mean my brand new fuel pump is knackered already?

What baffles me is i thought that the positive terminal on the pump would be the bigger of the two as well, but the earth terminal(-) is actually the larger one despite the + wire being the thicker? This cant be right can it? Is there a posibility i have had the wires the wrong way round?

Please help guys, its doing me head in!
