Was the relay bad? It could be the fuel pump itself.

The relay and fuse was changed, still will not start. The code is P0230.

Code is for: Fuel pump primary circuit malfunction. So it's either a bad relay(which you've replaced), bad wiring between fuse box, PCM and fuel pump or the fuel pump itself.
