Sounds like the contacts in the relay center have lost there tension. They are crimped to the wires and then just lock into the back of the plastic. Not fun but not real hard to replace. You also will want to test the current flow to the pump. As the pumps age they start to draw more amps and that heats up the contacts and causes them to fail.
