the fuel pump was making a very loud constant buzzing and then when tried to start it again it didnt even kick in

Ive just put a new turbo on (stage 3 cosworth) could this have caused it by the engine requiring more fuel and therfore burning it out. Checked the relay and this works so im puzzeled to what it can be

do I now need a bigger pump, where to get it from and how much. MORE MONEY
Thanks for any help Rob
