Fuel pump

(1990 Ford F-150)
I have a 1990 F150 with duel tanks. Neither fuel pump is working already changed relay. What else do I need to check before replacing pumps?

Check for voltage and ground at the connector for each pump when your are CRANKING the truck. You may have to lower each tank a little to gain access to the connector.
