Terminal 18 goes to the starter and is not a ground.
You must mean terminal 19. Terminal 19 PROVIDES a ground for the fuel
pump relay. If the pump relay is not closing for ~1 sec when you turn the key
ON, there are a number of possible causes. A bad brain is only one
possibility.
What are your symptoms? Do you hear the relay under the dash click when
you turn the key ON?
