1997 Ford Falcon not start

The car has full charged battery, turn on the key, all the dash board lights are on, when turn to start, no turning. I thought maybe the smart lock problem, but not. When I check the relays beside the battery, I found ants in the relays.
I clean the relay adapter and replace all relays, one 5 pin and three 4 pin.
now the starter motor can turn, but still no start, I found no power to fuel pump.
how to solve the problem? Thank you very much
