Can not hear the fuel pump priming when i turn on ignition. Car is also difficult to start when hot, but okay cold. Car runs fine when going. Have been told it could be the main relay but can not locate it. I have checked fuses and all okay. All started after i had fuel lines replaced. Any ideas on problem and where relay may be?

the fuel pump priming is normal, but if fuel lines were run to wrong areas, or one is blocked like a return may be problem. also plugged filter which is probably In tank on your car. there are three relays two under hood fuse box and one in dash box. see pictures.

Hi, i used to hear the priming of pump but now nothing at all since fuel lines have been done. As i have said it starts fine cold but once up to temperature if i stop car its difficult to start again, but does eventually. Can not think of what else it could be apart from faulty relay. should i return to garage that done the fuel lines or is it possible it could be the main relay?
