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

 

normally if they get noisey they are fooked, bridge the fuel pump on constant to check if it is the relay, have u got any fuel in it?

 

Even if the relay is clicking, it doesn't mean to say the relay is actually working and it doesn't mean that power is getting to the relay and through it to the pump. Check there is power to pin 30 on the relay and then when it clicks, that power comes out of pin 87.

 

yes fuel in it, will try it tomorrow

cheers

 

swapped the relay from the heated rear screen as thats the same and still not workin

 

New pump then!

 

check the heated seats fuse, in the fuse box!, and the wires on the pump!
