The fuel pump should run a couple seconds when you turn the key on. The relay is on the firewall. There is also a fuel pump fuse (20 amp), on the firewall, make sure its good. The wire that comes out of the relay to the pump is either TAN/WHITE or PINK/BLACK. At the relay the ORANGE wire should be HOT , 12V at all times.
